Ok so here is the rundown on my grow, I know I have made 4 consecutive posts but I had to take breaks and go down stairs for a little :stoned: if ya know what I mean . Ok so I have a 2 5 gallon buckets with one lid so resevoir changing is made easy. They will be covered in thick black tape in a week or so when I change the water so I dont have to tape a full bucket... seems like it'd be a bit more tedious. I have a whisper 100 pump running a 5 in. airstone and the whisper 40 running 2 bubble wands run circularly around the airstone at the bottom. I am using GH 3 part nutes with GH ph up/down, hydroton/rockwool medium. It has been about 3 weeks since germination, I had 3 seeds, 2 sprouted, one of the sprouts limped over and died. This guy is the survivor. I plan on topping it once it gets to that point, which by the way is when? I get pretty good ventilation through the vent on the side wall which is an inlet to the closet this is set up in. There is also an outlet which is the vent that the A/C uses to suck air so I have good air quality in the room. I use the heater below the vent to warm the air if its cool. It also creates some turbulance and give the plant a good little shake so I haven't needed an occilating fan yet. I was thinking of running some ducting from the side vent once I start to flower with an HPS so it can cool the light and the just run the end of it to my plant so the plant has warm air. Thoughts?
