ONLY when lights are OUT would I dump the CO2, in favor of OXYGEN. Seems like the problem is CO2 building up when lights are out, and damaging the plants.
In reality, its just as important to get fresh oxygen flow at lights out, as it is to supply with CO2 vs lights on.
If you want to be really technical.
But I agree its crazy to dump COs when lights are on, unless the levels get to high.
Whats up with the copy and paste charge?
I also used to be a Mod at Serious Seeds ( Jethro ) when Simon first started in 2006, but I got busted, and sent back to federal prison for 2 more years. I also did 5 Fed before that, and 6 supervised release. almost 13 altogether.
I was also a mod for Dan Van Pot, who was the originator of BC God Bud when they won the cup, but they screwed him over, so he took the Original Male, and left them with an Original Cut, but he took the male.
He started a forum, I was a mod with Astra007, you can probably google him. He got me the job with Dan, and was from Canada, as is Dan.
Dan eventually got busted for selling seeds, and website shutdown, Astra007 got me a job with Simon/Serious Seeds.
Dan is the only person who I ever saw to have the PURE RHINO. Not White. It was South African.
But Ive been mucking/frowing around with this stuff since 1972, and started using fluro in 76, then in 77-78 they came out with a Halide that was used on Navy Subs to grow/experiment growing in subs for better self sustainability, but the bulbs were fragile, and they wouldn't warranty them in shipping.
^ months later they came out with the Super Nova, and the Octagarden.
I went hard from 78-97 until my partner ratted on me, and I had 1000 clones. Which is Mandatory Minimum 10-Life, and up to a $5,000,000 fine.
The when I got out in 2001, I went another 6, and next partner ratted me out in 2007, but the sentence and eligibility for parole for the state, was less than finishing my federal supervised release violation. ( state ) ran concurrent to my federal Supervised Release Violation.
But I never said to dump CO2 when the lights are ON.
I clearly stated they need CO2/lights On, and O2, when Lights Off, no dumping CO2 during light cycle.
