Hello growers!
I have decided I need to run a journal along with this grow. Actually I'm already 3 weeks from germination and started getting some problems. I don't want to start a separate thread for each of these issues and many more I expect to encounter as I progress. So I thought a journal might be a good idea and that perhaps good people on this forum will offer some help and advice to get me out of trouble.
This is my second grow. My first was some 6 months ago when I grew one plant, Skunk #1 Auto in coco under 130W Citizen COB with some help of adjacent Mars Hydro Reflector 96 (183W draw) that was there for my hot pepper plants growing just next to the Skunk. Peppers were my training ground to practice germination, repotting, PH and EC, temps and humidity, lighting, etc., before I would start with my precious cannabis seeds. That Skunk grow exceeded my wildest expectations - no problems whatsoever - topped it once, light LST and just let it grow - no deficiencies, no nute burns, no pests, no nothing - pulled some 180g dried bud from that one auto plant in 80 days from seed!
Well, nothing could be easier, right?! WRONG!
I decided to do a two plant scrog. And right from the start - seedlings stretching, nute burn, deficiencies and fungus gnats. And I thought I was an expert already ha ha
Ok then, let's start.
As title says, I have White Widow Fem (White Label Seeds) and Northern Lights #5 x Haze Fem (Sensi Seeds).
I want to do a scrog in my 3'x4' grow tent.
I'm planning to veg to 2 months, perhaps 6 weeks if they grow big.
Flower time should be ca. 60 days for WW and 70 for NL5xH (according to Sensi).
As for the lights I have:
1. Mars Hydro Reflector 96 (5W leds) - 183 watt draw max
2. Citizen COB CLU048-1818C4 with few supplemental red Crees - 128 watts draw
3. 3x Citizen COB CLU04H-85/200-PRB that I built myself - 230 watts draw
I want to hang Mars Hydro over the NL5xH, my DIY 3xCOB light over WW, and that single Citizen COB somewhere in between.
That should give me some 540 watts of LED power draw over 12 sq ft - 45 watts per sq ft.
I am using Canna Coco Pro Plus mixed with 30% perlite.
For the final pot I'm thinking 4,5 gallon smart pots - feel free to suggest a different size. I have 3 gallon and 7 gallons smart pots at hand so I could use any of these sizes. But from a lot of reading I decided on 4,5 gallon.
For the nutrients I am using Canna line - Coco A&B, Rhizotonic, Cannazym, Boost, PK13/14, Mono Ca and Mono Mg. Obviously, I am not using Boots and PK13/14 just yet, but that's the plan anyway.
My previous grow was with GH Flora line and it turned out perfect. But my hydro shop only had GH nutrients with 2015 date printed on the bottle and I am not sure if that's production year or validity. Additionally, Grow component was having some heavy crystallization on the bottom (I hear I should mix it with hot water and all will be fine). Anyway, that crystallization along with suspicious 2015 date on the bottle made me switch to Canna - 2020 year looked so fresh
Other details:
Tent is 3x4x6' (90x120x180cm, I'm in metric btw)
Extraction fan is TD Silent with temp sensor, 135 - 200 cfm (230 - 340 m3/h)
235 cfm (400 m3/h) carbon filter
Passive inlets only
PH pen, TDS meter
Humidifier - for seedlings and early veg
Dehumidifier - for flower
Thermometers, humidistats, thermostats, timers and power meters - it's 21st century after all, right?
That's it for this first introductory post.
Next post(s) I will go over my progress so far with pictures, feeding details, etc.
Cheers all!
