I'm gearing up a couple of grow tents and thought I would stick some questions in here...
My 11 day old seedlings are looking happy. Where do you all securely host your pictures? I'm thinking Flickr would not be a good choice, heh. Probably not on my Facebook page where all my religious relatives share their bible quotes of the day
Veg tent. Homebox. Interior dimensions 39" X 39"
Carbon filter -> light hood -> 4" inline fan -> exhaust to room
Flower tent. Another Homebox 39" X 39"
Carbon filter -> light hood -> 4" inline fan -> exhaust through a pet door to second floor balcony
600 watt HPS too much for a 39" square tent? Hood will be well cooled. Or would a 400 be a better choice?
The pet door idea turned out to be good. I traced the dryer vent with a Sharpie on the heavy plastic flap. Then I used a box cutter with the blade heated with a propane torch and cut out the circle and mounted the dryer vent and sealed it with silicone. Some air will leak in but that's part of the plan. When it really gets cold I'll crank up a Mr. Heater Little Buddy propane heater to take some load off of the central electric heat while enriching the air with CO2. As soon as I figure out how to safely post pictures I'll give you all a look.
