Well I'm not risking much.
The worse I see happening is my plants die from heat stress and I start over next year.
I'm not a cash cropper or committed grower, once every year or two is fine with me. It's more of a hobby, I get more enjoyment out of taking care of plants (Not only MJ, lots of other normal flowers I grow too) then I would flying quad copters, or building a car, or even drinking beer and wine (I don't drink at all)
The smells is 99.9% gone, form time to time I'll smell a little hint of it, but honestly that could just be the weed I have out sometimes or possibly a gust of wind that blows some air out of the passive tents.
Overall I'm happy with the setup right now, I just wish I could have used my A/c sooner. I'm almost done already and I've been having to turn my lights down to 15% of their power in order to keep temps uder 85F.
I'm hopping by June 10th I'll be using my A/c so I can use full power for the last push of swelling.
As for the smell, I'm now using only giant 6"x24" filter with a 8in inline at about 50% blowing air directly out of my tent.
I have a 6 in inline and ducting circulating outside air through the lights to cool them some.
My room is nearly 80F the tent is 75F at 10-15% light power (I'm not exhausting in my room)
Weird shit I know, why I need the a/c so bad.
So worse that could happen, plants die from heat, plants don't yield much due to heat.
At the end as long as I have something to smoke be it making hash out of dead plants or bud, I'll be fine.
Just wanted to enjoy the summer without spending money on weed.
