Love the idea of using smaller retention walls and saving some money, thanks for the tip! And yeah I'm testing RH and temps over the next 48 hrs, highs and lows. I do have a inkbird controller to help stop major swings in temps. I've decided the nook is going to be a bloom area And the other part of the basement is going to be veg/autos.
That's definitely going to be a HUGE help!! The only thing I noticed in the Summer months was that the dehumidifier I run throws off a bit of heat, however this Summer, I'm going to have my grow's vented air piped into my house's HVAC to vent the warmer air upstairs where it can be either AC'ed or vented outside.. I'm not going to AC my basement, I've already told myself that lol
Plus when you have a few bad runs of autos because small genetics and constant variants in phenotypes that set you back it makes you think of a contingency plan. This isn't just my meds but it's also my job and only income to supply my patients. Yield as much as I hate to say it is a huge factor in my garden. And with a proper rotation of photoperiods I can harvest 3 half pound each plants every 30 days. 12 plants in groups of three all 30 days apart with 60 days veg. And that's only half my plant count currently. I'd need twice as many autos to meet that quota. Starting from seed every time you cant guarantee what your going to get..... Clones you can..... So I run both and fulfill my need to play around with autos and my love for growing while also making sure I meet my needs.
This is why I recently took the dive into growing photos.. Even though I haven't started cloning, a semi-shitty photo is still better than an "OK" auto, and there have been a couple instances recently where I wished I had grown even 1 more plant so my stash wasn't stretched super thin in between harvests.. Photos can take some abuse and just sorta grow in the background and as long as I water them and trim them back here and there, I can count on at least a couple ounces to supplement the auto garden I cherish.. I think you're gonna do fine man!!!!
I had thought about your dimensions and sorta reconfigured it in my head by having the larger area for photo veg and autos being 6x8 w/ the photo area being 4x6 as perfect dimensions, but you know your light coverage better than I do.. That gives you a 3ft path in between for movement.. Obviously that can be adjusted.. I look at those shelves and I envision either T5s or CFLs hanging from the bottoms of each shelf with trays of clones and seedlings rocking out and maximize your other spaces for SOG.. Just my $0.02!!
