Mrs. Resin, I can read just fine and can see you're negative with every suggestion given. If you're such HOT shit, then why are you asking for our help!?!
Rudeness such as this is not tolerated at the farm. LittleAmsterdam will be sitting on the bench for a week.
LittleAmsterdam, please take the time to read the Public Service Announcement at the top of your screen.
re: offgassing of plywood. i thought of this last week, but it seems that taped refectix would seal the room from the plywood. btw, i once read a study regarding this that showed that plywood offgasses for about 3 months.
re: rootzone temps. i've taken my hydro down to 53Âş (1Âş change a day) to test the "cold root" theory. people have told me in the past that anything under 60Âş would kill my plants. my plants showed no difference.
re: CO2. i once ran a small sealed room that was so well sealed that just the pilot light on my generator would take the room to 7,000ppm. i ran it that way for weeks and the plants loved it. and yes, i'd keep the door open whenever i went in the room.
