Hello world! I just started my first ever grow and I'm pretty excited about it. So far I think it's going well enough but I have nothing to compare it with so I'm really unsure. Just want to thank the creators of this site. I wouldn't be this far without the great information provided here!
For my setup I have a 48"x48"x80" grow tent.
600 watt MH light in an air cooled hood
6 inch 442 CFM fan with carbon filter
I have two 18 gal totes for top feed DWC with a pair of large air stones in each tote.
Nutrients are GH flora trio. I also use hydroguard.
I got my seeds from Nirvana. Growing wonder woman and ice. Both feminized.
I'm in Massachusetts and the tent is in my unfinished basement. I've had a heck of a time keeping the tent temperature and humidity levels high enough.
I'll be using tap water (town supplied) which tests at a consistent PH of 7.0.
I planted the seeds in the early morning hours on Sunday 3/18/18 (Day 1). I put them in rapid rooters, no pre-soak or anything like that. Kept the rapid rooters in a seedling tray for a couple of days until I saw some action. I then moved the seedling tray into the tent. I've had the light running 24/7 at 75% to keep the temps up otherwise it gets too cold. It was a struggle initially trying to balance temperature and humidity while still allowing for some air flow. I had to use the seedling dome longer than I wanted until I was sure I could keep it warm enough in there without it. Once they sprouted they really grew fast for the first day or two but now it's really slow. At one point the cotyledons were really curled up and I think the problem was a lack of air using the seedling tray and dome which also kept the rooters soggy. Late evening on day 6 (3/23) I moved the rooters to their netpots with hydroton and fired up the DWC totes. Things seemed to be stabilizing but growth is slow and it's taking all my strength to just leave them alone! Right now all im doing is checking PH every so often and I added a humidifier that I turn off or on to keep humidity in the desired range. I'm using a baby monitor to watch over temps and humidity.
So far the Ice has outgrown wonder woman at every step. The wonder woman seedlings really seem to be struggling. One of them only grew a single serrated leaf after it's cotyledons barely escaped the rooter. Another died when I was moving them into the netpots. I was holding the rooter and the sprout just fell off leaving the seed husk and root behind. My plan was to grow one plant per tote and have a wonder woman and an ice but if the ice keeps out performing I'll have a tough decision to make.
Latest numbers from today (day 9) 40% humidity, 74.5 F air temp. Water temps are 69.4 and 70.2. Current PH is 5.5 and 5.7. PPM 280 and 288. Light is running 75% at a height of 34 inches. The inline fan is off but I have two small clip on fans hanging from the ceiling on low pointing down. The two vents at the bottom of the tent are half open. The humidifier is currently off after humidity went up to around 55%. I'll probably turn it back on once it dips below 40%. I still need to take some exact measurements but I estimate each 18 gallon tote has approx 12-15 gallons of water. I added 0.5 ml of each nutrient per tote. I also added hydroguard based on the directions though I don't remember off the top of my head how much that was.
I'm most unsure about the lights and nutrients. Am I ok going 75% at 34" or should I drop the light a little lower? Is a PPM of 280 acceptable for a seedling or should I add/subtract nutrients?
