I’ve been using mega crop and so far I haven’t had any issues. Running a ebb and flow with tap water. I use a pk booster and feed 1/2 strength base nutes from week 6-8 and from week 8-10 I run the pk booster only.
I doubt you’ll have issues. I have the same type of setup as you but with 10k worth of light. Winter is nice though cause you don’t have to worry about ac costs. If anything, less humidity is better. No worries about pm.
You need to drill a smal hole in the little plastic elbow that is going back into the res. Also make sure that that little elbow is not submerged under water. I had the same issue.
For 60k you’re going to need a warehouse. There is no way you’re spending 60k on a grown in a residential.
I would pick up a hydro system with 5 gal buckets minimum. 200+ gal reservoir and have at it.
