Excellent Grow, Keen! I’m surprised no-one bumped this one. Very nice and uniform.
I have some experiences with aero too… (Look at my threads)
I’ve found this video of Amazon 116 internal workings…
Does the sprayer get clogged sometimes? What maintenance does it require? I’ve found my RainForest practically trouble free.
What about Reverse Osmosis, does it work as planned? Resulting EC should be zero, but what is your tap water EC? Luckily I’ve got good water practically everytime with EC of tap water never exceeding 0.2 and pH 7. So the only need for me was to take pH down with acid.
I agree that you have to find your own way with EC, because there are different systems and different strains have different needs. Also you shouldn’t overdo it or it will affect the taste of final product. Proper flush (at least for a week) is also something recommended.
Proper humidity is a key (same with fresh air), very informational topic posted @crazyben here - Vapor Pressure Deficit
I’ve got a question… I’m not so much fond of regulated ballasts. Have you found any advantages?
