You have 40 sq ft. To make that whole area a flower chamber it would be 2000W. Not sure how much you pay per kwh but that would increase my bill over $100 a month. That does not include the fans, pumps, timers, etc.

Given that same space I would section it off with a simple 1x1 frame and panda film (black and white plastic sheeting available at hydro store or online). Make a 3x5 bloom room and a 3x5 veg room for mom and clones. Hang a 600W HPS in the bloom and a T5 fluro or lots of daylight CFLs in the veg chamber.

Perpetual goodness

thanks for that suggestion, im so gnna do that. like, rly, look out for my journal within the next week.

edit : whats bette rto build the tent out of, wood or pvc? in terms of holding up my 400w which is quite heavy since it has no ballast, and i plan on having exhaust in the tent, sooo. idk. tent out of wood or pvc?
and yes perpetual goodness

Either will work fine. The commercial tents are made from PVC. The 1x1 wood frame would do the job and would be easier to attach the plastic. Check out you prices for material in your area. You could also look online for a pre-made tent. You may not find one matching the exact measurements described earlier. Most of the pre-made tents are square. 4x4 would be the closest to your desired size.

Buy some Epsom salt and add it to your feed a 1/4 to 1/2 tsp / gal.

Not sure if this slack ass town has Epsom salts would t he flowering juice work?

most super markets carry epsom salt.

$1.29 at any supermarket or pharmacy. You can use the FloraNova Bloom if you want but be careful not to overdo it. If you do that I recommend using just the FNB rather than trying to mix them.

How close can I actually put 2-3 inch plants to a 400w light? I dont want to fry them and I usually keep them pretty far away, but I dont think that there close enough.

my 400watt halide will fry my younger plants any closer than 18" and i dont have a cool tube... but you can put them up there and just keep your eye out on them

Peace

I can get my 400 watt HPS about 8" away.... although I do have to larger fans blowing though the canopies of my plants......

Has anyone here ever grown autoflowering plants under a 400w, and had good results?
