re: DharmaBud's First Grow Soil White Widow Auto & Silver LA-2013
Thanks Don, I appreciate the sub and your insight on the lighting situation. I have given some initial thought and I probably will buy some CFLs I will give my self time by growing the White Widow Auto first, then grow the plants this journal is titled about. That time should allow me some financial reprieve to gather what I need.
subd.
lets look at this lighting,
ok ive used cfls from start to finish, i used lots of 23 watt and 30 watt light, i used 2 to 1 ratio of 6400k for veg and the opposite for flower, now i know your not using cfls your using them long t5 strip lights, you say you got 8000lumin, well if you are going to go with the fl and cfls then you will need some side lighting, the t5's will be perfect above the plants, they will give you short node spacing and a nice even canopy, now thats the problem, a nice even canopy, anything below the canopy will be getting no light what so ever,
so the top bud site will be fine and the 2 branches below it and anything poking out the sides of the plant, but anything inside the plant and lower down will be getting no light and this will drastically reduce yield,
plus you need to consider that some plants grow quicker than others, say you grow an auto and a regular plant, the auto will be 1ft high when the regular plant is half that, so thats another problem, the t5s would be then to high to benefit the smaller plant,
plus if you start plants at different times you will also have problems, say the auto is finished in 6 to 8 weeks, well the regular plant will only be ready to go 12-12 by then, so once you harvest the auto you may like to grow another plant from seed, this means the regular plant will be much closer to the light than the seedling.
when i started growing i had no cash so i used cfls, lots of them, i kept buying a couple each week until i had about 8 to 10 above the plants then i had 3 or 4 cfls down the sides of the plants just hanging to get light to side growth and lower growth on the plant, this worked well and produced plenty of decent bud,
but one day i counted my lights then looked at the watts i was using, then i checked out a hps light and found a 400 watt hps puts out 55,000 to 65,000 lumins, i was using around 400 watts in cfls so switched to hps, now others say cfls and fls produce more heat than hps, welll id have to say their wrong, when i was using just cfls i could get away with small 12v computer fans in my room and could have the grow door shut, im now using 400 watt dual spec hps and i have to use big fans and cant have the door shut as i dont have a decent vent set up, i cant as its a brick built drying cupboard and dont have an outside wall.
so you really have a couple of options, the t5's will work really well for seedlings and small plants, when they get to roughly a foot high you would then need some side lighting to make sure the plant is getting the most light giving you the most growth, so id add say 2 x 23 watt cfls at either side of the plants, a better option would be another 8 23 watt cfls and have them hanging around all the sides of each plant, that will give you a decent yield and light coverage would then be ok,
my dual spectrum 400watt hps cost me £65 and £12 for delivery, it came with digital ballast and a dual spectrum hps bulb, now because its dual spectrum it means i can use the same bulb for veg and flower, no need to mess about with mh for veg or hps for flower, plus if i did want to change to mh for veg then the ballast works with both types of bulb but i find the dual spectrum does its job well as long as temps are kept in check
ive not used t5's so cant comment on light penetration with them, but the best way to test would be to switch the light on and wait a few minutes till they get to their brightest, then hold the back of your hand against the bulb and slowly move your hand away, you will find that after just a few inches the light drops off pretty drastically, the same happens with hps, even though a cfl or hps will light up a whole room, the actual light brightness drastically drops off pretty quick after more than a few inches, i know with the cfls i use that after about 2 inches the light drastically drops, id say more than half after more than a few inches,
so not sure how that goes with the t5's you have got but their fl lights so i guess their pretty similar with light penetration,
it also depends how big you want your plants, just remember some double in size and even triple in size when you flip the lights to 12-12.
with the auto you will find that when it starts flowering you will need to add more of the 2700k spectrum or as near to that as you can get with your lights, i cant remember what you said yours where but when the auto is in 2nd week of showing flowering you will need to switch to flowering lights until the auto has finished so if you got an auto and none auto growing then you need to work out the lighting to keep both plants growing at their best,
a lot of growers knock cfls and fls, but i still use them for seedlings and clones as i find the node spacing is a whole lot better than when i start plants under the dual spec hps, maybe its because we can get cfls much closer but i like the spacing so i use cfls still to this day and will continue to do so, when i used cfls from start to finish i think i ended up with about 2oz off one plant and between an oz and 2oz on average but i was using around 400watts with cfls and a mixture of 23 and 30watt cfls,
all you can do is see how you get on, fls and cfls do work and their have been some amazing grows on this site done only with cfls so they clearly do work and clearly produce some very nice buds, only downside is light penetration, so as your plants grow id just add some side lighting, the regular househould cfls that you usually get free from energy companies are ideal for flowering, a lot of the £1 and $1 stores usually sell the 2700k cfls or super markets sell them in packs of 4 for next to nothing, the 6400k cfls are a bit harder to get and super markets dont stock them, i had to go to lighting shops and order off the rain forest sounding site to get the cfls for veg,
so im subbed and cant wait to see how you get on with these lights, do it right and you will have amazing results, use some basic lst to open the plant up to more light will really help loads, just use pipe cleaners or some sort of string to pull branches one way or another so their not blocking the branch below from the light, i pulled leaves out the way and branches and the more light you can get onto all the growth the better the yield will be,
im sure you will do ok, their is more help than you need on this site.
