I’d put a secondary drain pan under that bad boy. May keep you running one day, and keep water off of your grow. Maybe a Romex connector on your hi voltage wire too

The drain goes out the wall and yea the power wire was just temporary for my ac guy as he came a week early and had me scrambling when it was 90 out lol
what yield per plant on 6 footers?I have a mess of tall plants right now but they are way too close to the lights and probably gonna fall down. With gavita or even reg hps id run like 3 foot deep canopy with led i keep the canopy dense but not so deep. but on this tall ones i didnt lollypop much so well see if the bottoms finish up. I think they will.
The secondary pan is for when your drain clogs and the unit floods, it’ll happen

Anything over 50 tons of cooling in a facility is where it makes sense to use a chiller. We have a 215 ton Trane unit I bought for $10k off eBay and I have two more 550 ton units going in for our next phase that we’re only $30k total (again, used off eBay). $30k for the cooling tower plus another $50k for pumps and piping. We’ll be at about $200k for pumps and piping for the additional 1100 tons. We use CRAH units from data centers, they’re the best bang for your buck for AHUs. We get them used our of data center refits, about $4k per 30 ton unit. We modify them to add hot water reheat and use them for dehumidification as well

Your pushing 20 de? Are you having humidity issues of being too dry?.
I have closed room with co2
Are you following a vpd schedule? Im just learning about?
Are you using humidifier to raise humidity? If so scale issues as well?
its an odd issue to me. id put something under the plants to prop them and keep a bit of water underneath and that should get humidity up? its never been an issue to me.
Do you use use a thermostat on your ideal air? Lux, trol or other?
