How many de 1000 watt gavitas should i run? It calls for at least 32 lights right? How much air conditioning will it require? 15 tons? Or should i run 20 tons ( 4 5ton mini splits) to account for dehumidifier and co2 generator?

Im trying to open up a medical grow in oklahoma and needing to order up the equipment.
Also what is the best rez to use with a 5 ton ×ater chiller? For sure need something insulated. What are people using?

Im trying to run 4 ucdbxl32s

Also, random question but, do you have any external air coming in? Does that ruin you insulation? Or do you not need fresh air from outside.

I do not have any external air coming in. I have a 12 in fan suckinv thru a filter out of my room and then into as another 12 in fan blowing back in. Thinking about putting a 6inch fan and filter with a speed controller to constantly suck air out. I'm not even running co2 right now. Should help the smell. My neighbors complaining.

How many total sites were you able to fit in there?

76. 2 32 site and a altered the manifold on the other 32 and made a 12 site. Still have plenty room to work. If I would have done all 96 it would have been impossible to do change outs or fill top off res.

Root pruning is more important than about anything else in these systems. At least for the 8gal with 2in PVC. I have already caught roots trying to sneak down river. Saw them peeking thru to the other bucket. I try and hit them every 5 days at least. I'll stop the end of week 2 and not touch them much after that.

Do you keep the lights off when you’re trimming the roots? Or is the whole make sure not to get light on the roots thing overblown

How was your final pull on the 64 site initial run?

I only ran 1 system with 31 plants. About 13 or 14 lbs not including what I blasted and the little bit of airy buds. I stunted them good in the beginning week and then right at the end. Learned what happened and am keeping better eye on them. Literally half the plants felt the shock

Imo overblown. They wont grow well with light but a few seconds dont hurt I dont think. They grow back within 48hrs and have to do it again. I hope I dont have to do it any more after end of week 3.

That’s crazy that you were able to still pull 14 after the issues. I think once you’re dialed in, it’s going to be possible to get close to 60-65 lbs, though 95 may be pushing it.

You having any circulation or humidity issues? Any powdery mildew while running at full blast?
