Question for my planned grow Room

Presently I am waiting for my ontario MMAR Personal use Production licence and for me to receive it i have to submit my plan to them on how It will be set up more then likely I will recieve a licence that will allow me to produce around 300grams per month as I ingest it for pain ,muscle spasms, chronic spinal pain (due to being dragged by a drunk driver over the hoods of 3 cars),Fybromyalgia and nausea, but also smoke it for Chronic insomnia ,chronic fatigue ,anxiety,depression and sleep apnia. Anyways Sorry I digress and its been forever since i could speak about these problems to people who understand the choosen care method I have taken to to solve these problems.. Anyways the grow room


I am planning on converting a bathroom that has become obsolete since we expanded the house and added a new one with jaccuzzi so what i have to work with is a 9'x7'x7h room that has a closet approx 30"x 3 feet deep by 7 feet high now what i plan is to remove the toilet from its fixture and place a basin there for drainage and tie the sink pipes into it for water access so now we have a bathroom with a plastic washing sink and a bathtub and closet not gonna bother removing the tub instead will leave it in place and put a sheet of plywood over it approx 5'long by 4'deep so it is haning over the edge of tube about 1 1/2 feet will then brace it with 2x4 legs on this i am planning to place a 3' x 4' ebb and flood table with 30 4 inch pot holes. Now over this I am planning to hang a 400watt hps bulb with reflector and ofcourse mylar off all the walls and make a mylar reflecter for open side that can be moved away to make access easier . then add in my in room circulation fan to create some intra room air movement for the door I was planning to put in a couple of 40$ squirrle cage fans one with a flexible 4" tube wich i can tie in to the chimmney exhaust as this will be a legal production for medicinal use i dont have to worry about police so onwards. also ther will be a squirrel cage as an intake fan. then inside the closet i will be installing in the closet that has shelving that allows me to create 2 3 1/2' high x 30 wide x 3'deep areas where i was thinking I could place 2 4 bulb x 55 watt flourescent fixture and a couple of small oscilating fans in each level and i can also install 2 more intake/outtake fans inside the closet one wich can be tied into the other outtake fan from flowering room or do you think just an intake fan will suffice to bring fresh air into this closet and let the warmer air be forced out or should i extract? ? i think i should be able to place 4 -6 plants within this area if I keep them short and bushy enough that i can get 30 cutting from them at any time should this be easily done? and is this space sufficient to keep these mothers alive
also I have another pantry just outside the old bathroom where i can install a 3' 2x40' blue white flourescents for a nursery for clones or if god forbid i have to start over from seed. okay so that is my basic IDea and I guess my questions are as follows

1 is a 400w hps and 400w mh conversion sufficient for a 3 x 4 ebb and flow or should i consider the 600w hps and if so is the hps able to help me veg decently for say 2 weeks before flower if so then ill go with 600w hps

2 do you think heat will be much concern in this room with either 400hps /400mh conversion only using a couple 40$ squirrel cages or using the 600w hps
oh i should mention this is in a basement where during the summer the with central air on we are usually at 65 farenheit at night throught entire basement including this room if so need some idea on inexpensive ways to reduce heat should i run a flex pipe from an inductor to have it blow thru the light fixture or just more intake air.

3 is the suggested closet suitable for mother storage running on 18 hours a day both light fixture will be either using 4 55wat white blue flourescent or should i run the full spectrum bulbs also will a couple of small 10" occilating fans enough intra area circulation and will i need to pump the air out of the closet or will just pumping fresher cooler air from outside the bathroom be enough with no need to extract as there are enough cracks around door to allow a fair bit of air movement from the internal pressure. All opinions on the safety on mothers is requests and actually appreciate if you see a potential problem please tell me.

Ok the nursery for clones i have pantry where i can put a clone propegator under a 3' 2 55w bulb fixture to help them get there legs and start to spruce up where the top 25-30 clones will be moved to the table to commence 2 weeks or 18/6 vegitation under the 400w MH or if a majority think that a 600w hps will be able to provide equal or close to equal growth rate in the veg cycle at wich point will drop to the 12/12 light cycle and ofcourse switch to blooming fertalizer also I have seen advertisements for Co2 pucks that we drop into our resevoirs and it adds Co2 enrichment are these even worth it or safe or has anyone who has used them seen no difference in growth just needing an opinion or would i be better off stealing my brothers 20gall Co2 tank when away and use it to enrich the grow room when possible. Also i have read some stuff about running airstones in the nurtrient resevoir do they really help increase plant growth and also do they promote greater branch growth as i have also read,and while on the subject of increased production i was told that nitrozyme or something along those lines when misted on to the newly forming buds to increase there growth i was told by an outdoor grower I know that he believe the nitrozyme increase his bud size and density by 20-30 % when regulary treating the buds is this true?




WEll that is my plan for the room as you can tell ventilating the grow rooms and trying to maintain a temperature of around 78-80 during lights on from personal experience I would say that bathroom does drop down to around 65 during the evening as with all basement apt the floor is only set 2 inches above the concrete and at times its been known to get fairly cool i would estimate it gets down to 58-64 degrees so you have my basic layout of how i plan to run my system so anyone with experience feel free to point out any problems they seen and the cheapest easiest way to fix them . ALso will it be worth my while to borrow my brother 20gallow Co2 Tank he uses for charging his paint ball guns canisters is this the same co2 used to help speed up the growing of pot

Well this would appear to be everything i can think of if yu can think of anything i am missing please reply also big question is will i have enoug ventilation for a 600w hps bulb or would it be safer to go back to the 400w

and once again is a 400w hps and 400w mh conversion give better yeild over a straight 600w hps as some of the strains i am looking into procuring will yield 600-800g/m2 and a lot of time i see seed banks list yeild as 1gram per watt would this mean although growing a strain that predominately produces 500-600 grm would that mean a 400w bulb wouldnt allow the plants to reach maximum yield
 
1st let me welcome u to our forums.Congrats on ur license. WHat must one do to aquire one of those? This is a long ass post. This site has a lot of stoners=lazy. So lets break this into sections so we can all take a stab at it. In response to

I ve used a 600W to cover a 4x4 area. U can get a 600W conversion bulbs as well. When choosing a light think heat dissipation, coverage area,wattage, and headroom (how much space the growing plants will need to finish;how much space do I need between the hood and the ceiling, as well as the hood and the canopy). I would suggest going with a square shaped, aircooled hood. U will also need ducting and a sufficient inline fan to push/pull air thru the hood to keep it cool.
 
First off thanks for the reply and basically i am thinking that from what you said using a 600hps for a 4x4 ebb then the 400hps as well as using a conversion should allow the strains i sent for to reach there max yield in a m2 or at least give the max yield mark a good run for my money. Basically I have already identified 4 excellent dutch strains L.S.D from barneys farm this is a plant that will produce a yield of 600-800gr/m2 in a SoG configuration garden and will produce on average buds of 24% thc 1.3% cbn .7% cbd(i think this is the last ones name) anyways due to the multiple conditions I will use weed for I need one with a massive body stone when ingested ,another that is very narcotic and drowsy and then some mild mid day social weed so that stress and frustration dont have me trying to tear the bank managers head off again. acck I digress again okay back to the grow room its total size is 358 cubic meters or 63 square feet of floor space on general the room reaches 65 degree's or sometimes lower at night during the winter and never gets warmer then 70 during the summer so with a couple of squirrel cages for intake outtake as well as driving air into the reflector to cool the light do you think I will have a hard time with heat or should i easily be able to create a 15 degree difference in temperature between light on and lights off.Next question the closet wich i can create 2 3'Hx32"wx3"D spaces should these be sufficient to maintain my mothers in using only a 4x 55w flourescent full color spectrum lights be good enough to create good healthing mothers that I will be able to get between 25-35 cuttings from every 2-3 months. The mother room is the heart of this attempt to grow my own medicine and I really cant afford to buy 30+ feminized autoflower seeds every 3 months or so. Also one thing i am wondering is about Rock wool i see them selling rock wool in 2"square blocks 3" etc but the table i have checked into has to configurations either 15 5" pot holes or 30 4" holes now what i am wondering does this mean i have to use the 4" square and 3" sqaure rock wool cubes or do i use the 1 or 2 inch cubes then anchor them in those net baskets with that brown rocks stuff i see to anchor them? I only ask as i can affor 12$ for 50 of them but the higher prices of the big cubes is way out of my price range as i am basically looking to run my system at around40$/crop for nutrients growing medium, pest control etc per crop once the bigger expenditures are done. Is this a reasonable figure in cost if there are no disease or pest problems. Also Wondering if it is worth the trouble to place 3-4 venus flytraps in grow room to help with insects .

Oh for obtaining a canadian MMAR exemption is actually fairly easy if you suffer from a terminal or permenant disabling conditions such as Cancer,MS ,HIV/aids,glaucoma.Certain types of arthritis or chronic/intractable pain due to spinal chord injury you will be in the category 1 list wich only requires a GP signature any other ailments fall into category 3 wich requires a specialist in my case my Doctor for pain is also my GP, is a registerd pain specialist as well as a doctor for the OATC (ontario addiction treatment center) I met him after my fourth year of taking oxycontin for the pain was up to a does of 120mg per day or 40mg 3 times a day also the doctor was prescribing me 80-100 percocets for break thru pain and then massive amounts of toradol for the muscle spasms only problem being was although initially this treatment was successfull within 6 months my tolerance to the opioid had become fairly strong and on average It was nessecary for me to have my prescription increased to 1 80mg oxy in the morning another 80mg 8 hours later then 8 hours later a 40mg tab so altogether i was taking 200mg oxycontin each day as well as another 4-6 percocets then the anti inflamatory meds and then the muscle relaxant toradol wich in my opinion is a very strong muscle relaxent. Okay on to obtaining the MMAR so you will need to contact health canada and Have them mail you the MMAR application forms for you doctor to fill out on this form you will be informed that once approved you will have 3 options to obtaining your medicine 1, You may purchase a 1month supply at a time from health canada at the price of 5$/g $140 /oz 2. you can opt to apply for a Personal use Production Licence (PUPL) 3. You can also designate a person to supply your medicine to you where he/she will have to apply for a DPPL (designated person production license) also as a side not a medicinal use in canada who has his PUPL can also obtain upto 2 DPPL's so they can legally supply fellow medicinal users who are unable to grow themselves but would like to be involved in whatever way they can in the creation of there bud. So once you have a Doctor who is on board with MEdi Herb you have him fill out the government forms and the rest of the process takes 8-10 weeks to obtain your mmar licence wich will have information for police on

a.) quantity the user may have of dried/cured marijuana and the method in wich the doctor wants you to use it either smoked or ingested or a combination of both

also the above is for people who have only obtained licences to use and store there marijuan also these people are only allowed by law to have no more then 1 months supply of dried herb

b.) the quantity of plants the producer is allowed to have flowering in most cases it is usually 25-30 plants also determined by daily prescription so if your doctor prescribes say 4grams to be smoked daily then you will receive a license to store a 4 month supply of dried herb or 120days *4g/day = 480 grams

C. you have to submit health canada with you plan for your grown room as you can see from my first post that I have this mostly figured out along with yourgrow room plan u must also submit you plan for disposal personally before I even begin to grow I will be visiting my local police station show them my plans and find out if they will accept me bringing in my stalk leaves and any excess bud that pushes me over the maximum of what I will be allowed to store. In my case my doctor has already suggested that I ingest as well as smoke my herb to help with pain , muscle spasms and nausea and smoking is to help with insomnia,chronic fatigue,stress and mild depression and as he figured I will need 4-5grams for smoking and another 5-7 grams for eating so he is thinking that my daily intake will be between 9-12grams per day but i am thinking 9gm /day will be sufficient as that is 270grams/month so personally if this all goes thru my licence should allow me to grow 25-35 plants and store 1100grams of dried marijuana for a 4 month period also the MMAR licence has to be renewed annually but only requires you to get what in essence would be equivalent to a normal prescription refill just to inform health canada that there are no changes unless your doctor believe you should increase you prescription size he can then submit a new dosage reccomendation so that your licence is updated properly so stored amount is increased and number of plants your allowed to grow is increased as well.

If ur considering using a 600W over the tables, what's the 400W w/conversion bulb for? If u have anymore compound questions. Please break them up so we can tackle them a little easier (1 part at a time). If u have pictures of the actual space that may be helpful to envision ur schematic.

first off i just looked back at my original post and I appologize for that bizzare diagram it was done in ansi and looked proper when i did it so ill just explain with straight dimension

Room is 8' deep 6.5' wide and 6.5' high along one of the 8' walls is a 5'long bathtub wich will be covered with a 5'x 4' sheet of ply wood on this wall as well is a 3'W x 6.5'h 3'deep closet with shelves at 3.5 feet giving me 2 3x3x3 spaces for mother plants if this is big enough for them using flourescent banks with 4 55w blue white bulbs.


The table will be a 4' x 4' ebb and flood table .

now what light will give me best yield a 430w hps using 2 weeks under a 400w mh conversion for veg before bud

or going with a 600w hps for 2 weeks of 18/6 and then cut back to 12/12

or a 1000w hps hydrolux using the same method as the 600w


or the 600w hps with 2 weeks under a 600w mh conversion for veg

i am looking for best yield to cost ratio with cost of initial setup being main concern as i dont want to ever change my set up ever
and also i dont want to buy more light then i need especially as i only have about 150-240$ for ventilation not including in room fans for creating movement and i dont want to have light that is wasted and i want to make sure every plant gets what it needs to finish like a monster also just so you know when answering this 4 x 4 table will probably be holding between 25-30 plants if this is more than enough room for that many plants should i go to a
3' x 4' ebb and flood as it will save me 120$ and please when answering take into acount the room is 280 cubic feet and i want to try for 75-80 degrees lihts on and 60-65 when lights are out. and again sorry for my dyslexic diagram in the earlier post if a mod could switch this post to where my original was that would be the bomb
 
Just to clarify this is not a comercial operation but my doctor is putting me on a 8-10 gram/day prescription which means i need to grow enough to last for the time it takes for next crop to mature and at 8-10g/day thats 240-300 grams per month so basically if my strain takes 10weeks to flower thats 2.5 months so 2.5 x 240-400 =600-1000grams every 2 months. So i am just trying to figure out what light i need for a 4 x 4 table using the SoG method i just want to make sure that all the flowers are able to finish or at least 80-90% of all the usable bud as i was considering storing some pollen If the methods i have read about to produce some male flowers buy leaving the plants and extra 10-14 days will work . As i have read if you leave your plants an extra 10 days or so it will produce male banans that arent able to fertilize the plant they grow on but are excellent to save to use on the next grow in small areas to have a few smaller buds produce feminized seeds so if god forbid i get a crop failure ill be able to start over without a purchase to the seed banks in amsterdam (luckily here in canada we have a seed bank that stocks seeds from the major banks in amsterdam) My other choice if worse comes to worse is Ill be able to have health canada send me 30 regular seeds from there medicinal crops out in manitoba but these are all low -med thc producers averaging <8%-15% thc but from what i have been told by people who obtain there seeds there they think they are averaging 10%thc in there plants
 
I meant no offense. I just figured that commercial growers keep better track of profits and expenses and such.

none taken i am just trying to maxamize my yield for the space i have dont want to waste light by buying a bulb that will produce more power then the plants need as its a double loss in cost of bulb and waste of power. Sure wish there was a guide that could explain how many watts per m2 a garden requires.

originally I had a couple ideas

First one is a 600w hps and 150w mh wich i will manually switch from side to
side each day,
2. 1000w hps with a 1k mh conversion which i will use to veg for 2 weeks then switch to the 1k hps veg periods in either case will be 18/6 then flower at 12/12

ventilation consists of 3 75cfm muffin fans one of wich will be feeding into the larger lights reflector wether its the 600 or 1k also room will have a circulating fan to get the air moving to strengthen the plants. oh also the basement where my room is usually sits around 65F -70f all day long even during summer we rarely get heats much about 75-78 so bascially wondering if ill have enough exhaust if i go with the 1k watt bulb but i dont want to sacrifice yield so I would prefer to add more ventilation possibly tie the intake that cools the light into the homes cold air return and see if this helps as well i was considering running the intakes to draw from the cold air return as well.


If worse comes to worse i can throw some cash at it to fix problems basically i have 1750$ to build my grown room motherplant room and nursery for clones .
 
Well I did a bunch of research today and found a link that is the bomb when it comes to helping you make your decisions on how you will set up your grow room. This handly little site will let you put in what a seed bank states is the yield for say a 800g/square meter you enter yield in appropriate place lumens of your light and then intensity and it will then show your canopy space required and the expected yield also has a advanced section for when you make upgrades not in yield section u can put in what you actually have grown with your set up lumens and what light intensity you either have measured or estimate and it can tell u if your doing a good job. Well here is the Link let me know what you think YOR - Yield Calculator for Upgraders
As a first time grower what I did was enter the average yield the seed bank stated the strain could produce per m2 entered that into yield then adjusted lumens of hps and mh combined and intensity till the yield expected equaled what I entered or the seed banks estimate so for example if you Were to order g13 haze from barneys farm feminised and grow it on a 3 X 3 garden you would require a 600w hps hortilux with 2 extra 50 w metal halides with light intensity of 9300 and in one m2 you will produce 500 grams as listed so if you are using a 4 x 4 ebb and flow system you would need a 600w hps hortilux and either 2 150w mh with a light intensity of 5400 should yiels aroun 850grams plus would be higher but a 4x4 table is actualy 1.8/m2 if we had 2/m2 then with perfect care taken reaching the 1000g mark is quite posible,Just a matter of learning what the strain needs you should all check this place out is excellent place to plan upgrade when wanting higher yield and from what I can tell if you already know what you can grow using what you have its really quick in telling you what upgrade are worthwhile.Looking forward to experts having a peek and telling me if this is a worthwhile site or if the creator is way off.
