Ok so after much thought I’m installing an18000btu mini-split in my flower room next week.. I’m currently running 1890w of Cmh over a 4x8 table but I’m plotting on adding a further 4x4 and another 630de Cmh for my next run as it will just fit. I’ve been growing for a few years now but I’ve got no firsthand experience growing with an a/c but it’s now time to learn.. My room is obviously currently vented so my first question is when running a mini split is it best to seal the room and if so do I then have to supplement co2? Could I vent during the lights out period and would this venting supply enough co2 or would I have to periodically vent during the lights on period to have sufficient? My room vents 24/7 as it is now but surely that will have a hugely negative effect on the efficiency of the a/c? Constantly sucking all the cooled air out..
I’m definitely not against completely sealing the room and running co2, although the initial outlay is pretty heavy but if it significantly increases my yields I’m fine with that, if it’s marginal however then I’d rather do without if possible. I’ve read various findings on how much difference supplementing co2 makes.. from significant to marginal
Please give me some guidance on this guys.. I know I need the a/c but I want to set things up right the first time.. I hate doing shit twice
