ratio on my hanna meter is 500-1 i think. have to double check. the run is gonna be a no additive run. dynagro and bloom vs. sensi grow and bloom. straight up who has the more complete base nute. i've never even seen all the additives an has but if you check around my threads you'll see i've grown some serious dank using AN and 1-2 additives.
definitely putting H&G into the test. i have never run them before but a buddy of mine does and loves them so i got a bunch of their base and additives as gifts from greners.com and i want to try them out. experimentation is half the fun for me.
i think i would be more inclined to experiment with it but as you may have noticed i live in Costa Rica most of the year and that is where my grow is. Access to salts, macro and micro nutrients is not as easy as in the u.s. not even sure if it's possible.
air temps are perfect. i think you'll need a bigger chiller though. probably 1/4hp. water temps should be around 68 degrees.
they do put off some heat so you will need to compensate for that. they aren't inefficient like you might be thinking...they are actually about 30% more efficient than an a/c...but a/c's are inefficient too. it's just the lesser of 2 evils.
the lights all have Ice Box Heat Exchangers on them. I can lay my face on the glass of a 1000w light that has been on for 48 hours and not feel a thing. The water cooled air handlers are for ambient heat. That's why i have a 6 ton chiller.
