Ah ha!
You have a big time grow going I see. The electric company has found a friend
I'm growing 27 plants now in bloom, with 15 in veg at the moment under a combination of LED/HPS totaling 5840w running 11/13 for bloom and 18/6 for veg and that cost me last month living in CT $525 for my total electric bill, so expect too double that.
I sell 2 zips ($325 per) and cover it so no big deal, but I hope you have enough customers to buy all that herb you are growing, because you are going to hopefully have a lot of herb to harvest/dry/cure and sell
Do you add beneficial microbes to your res?
That is an important additive in the 1st month of DWC especially, not needed after that.
The air stones are a good idea, as they will help your plants deal with water temps, in case your water gets too hot.
Just curious, how many grows have you had using this system and this many plants?
The reason I ask, is that you are in for a world of work with that many plants, so be prepared (drying racks, trim cleanup, jarring and cure time)
Good luck BrutalBuds, I wish you all the best.
Oh, save the Neem oil until you have an issue
