Hi Weedhound

Good to see you taking an interest. I defnitely take your point on the ventilation & as mentioned I have already cut the hole for an inline extractor. Although I wouldn't mind your opinion on if it would be best to have an extractor fan with passive intake or forced cool intake with a blower and passive exhaust. Wouldn't mind keepng the costs down a bit during the first grow.

However I have been looking around for info on CO2 and although I havent found a thread yet which really goes into the details. In the FAQ section he thread

Post 12 metions a bit about CO2 and thats its best around 96. From other snippets Ive got around here it seems to me the basic idea is to increase the CO2, let the plant breathe it and recirculate the CO2 filled air then flush the room with fresh air, repeating this process on a schedule.
Would there then be any value if my high temp schedule is between 6 am & 8am to fill the room with CO2 it would then get fresh air when the door is opened and then repeat the process at dusk when I have to close the door again or risk my neighours asking if they can borrow my sunbed.
JackHerer Reviewed by JackHerer on . Caduceo's Hydro Grow Log Hello everyone, I am a first time grower. I am using Emily's Garden, a 6 piece wick style hydroponic garden. I got the seeds mixed up when I germinated them, so they could be white widow, or lavender kush, or shiska berry. My money is on Lavender Kush because I have the most of those seeds. I got the seeds from a dispensary, they came with the weed. My grow room is a very small 2x2 closet with a ceiling of about 10 feet. I have a 400 watt MH, and a HPS bulb for flowering.
