I'm looking for any advice from more experienced growers. From what I hear this is the best way to get big yields with limited lighting. I have 1000w switchable ballast and a 4x4 tray with 16 hindu skunk plants. I run a dehumidifier and 2 oscillating fans 24 hours a day. I have an AC unit that I run as needed. I have an air cooled hood with air coming in from and venting back out to the next room. The CO2 is set to a slow leak during lights on and is distributied with one of the oscillating fans. If anybody can see any problems or has any suggested improvements I would be very appeciative of your input. I also have a few other questions that I hope some of you gurus could weigh in on. Thanks in advance for the help I'll try to get some pics on here later. I just started flowering 3 days ago.
What is the ideal temp when running CO2? I've heard that you can safely go hotter but for max yields you want about 75-78. Is this true? How about during lights out? Is it worth running my AC during lights out if the temp is about 75 as is? When I don't it seems like it gets stuffy in there.
How much nutes should I use? I've heard you can use more with CO2. I'm using supernatural nutes and liquid karma. The instructions say to use 1000 ppm. Should I do more? If so, how much and how do I know if I overdid it? Do I need to flush for longer if I use more nutes?
Should I try to run in fresh air when the lights go out and the CO2 goes off? Or should I keep the room sealed at all times? A friend of mine was concerned that the plants would not get the 02 they need during lights out. I had a fan bringing in fresh air through the window but took it down and closed the window to avoid wasting CO2. My friend thinks this was a mistake. I've read that one of the big advantages to having a sealed room is not allowing anything dangerous to come in with the fresh air like mites.
Do I need a carbon filter? If I get one I'd have to buy another inline fan as well so would rather not but I will if the smell is too noticable or if the benefits are worth it. From those of you who have done this before: How contained is the smell in a sealed room with 1000w? What benefits will I see from scrubbing the recirculated air?
Thanks again for the help guys:jointsmile:
