First of all...such a great thread Tran. Really. Cheers :beer:
I actually came back to read it thru again as I'm considering going to a fully sealed setup. I came across a couple new posts since I was around last and have a question for ya regarding the above quote...
In my experience, everytime, without fail....not having some sort of fresh air coming into a vegging room has held the plants back. For example, lets talk about a 6K setup with 200clones. If the ventilation stays off for a few days (usually cuz it's so cold and dry outside that it'll pull the room humidity down way too low)...but anyways, the plants will be looking droopy, even tho they are growing ok. Within 10minutes of turning the outside ventilation on however...BOOM! The plants just perk right up and start rockin hard.
So I'm a little confused.
You're saying your room is 100% sealed up and no CO2 until wk1 of bloom...so that's a week or 2 of no CO2 and no outside air. I'm having a hard time getting my head around that....
