Can you pull your intake air from under your house? Do you have a crawl space? That air will be cooler in a lot of instances.
Nah, I'm on the second floor of this home, it would require many many feet of ducting and it would have to be run outside the house (which would look terribly ugly). Worse though is that our basement flooded a little while ago and there is lots of mold and other nasty shit down there so I wouldn't want to be drawing in 'fresh' air from there.
I'm good right now with the passive intake taking air from outside my window, it's fresh air from the outside. The small intake inline fan I had broke so it's all passive right now but when I get some cash I hope to get the intake going with a fan again.
It's hard to tell if the 2 changes I've made had made much of a difference yet because the weather has been pretty cold, plants have gone as cold as 66F during lights off, and I think they are like 78-80F tops during lights on. I need to get another programmable timer so that I can cycle the exhaust fan on and off during lights off cuz I have the feeling it's getting that cold since it's constantly drawing in cold air from the outside, would like to have the exhaust fan go on for like 5 min every half hour during light out.
I also need to buy a good dehumidifier (any suggestions?). I also need a job lol cuz I can't pay for any of this
@Grilledcheese looks interesting, but for $100 that's already nearly the cost of a regulator (actually a regulator is about $80 I think), buying CO2 tanks isn't that pricey, its the regulator and the tanks that are too much for me at the moment. Will try getting tents temps down first, I don't *want* to use CO2, just trying to find ways to deal with hot temps that will give my girls best chance of growing fast and I know their stagnated growth in hot climates is alleviated by increased CO2 concentration so they can photosynthesize more efficiently.
