Honestly im using the Mars Hydro ts1000w, its amazing for the PPM. It does get warm in my 2x2x6 but with several fans , great air circulation, keeps it @ 77* day, 71* night and humidity based on my plants week of growth. but i dont hit my plants with direct wind either (Mine hated it, leaves wilted) My plants hate excessive nutrients too, i use the fox farm trio. Just PH down my tap water to 6.2 and water when needed. Perlite/soil is 40/60 or 50/50 , i like it airy, using organic Natures crap soil but its working lol. The Mars Hydro ts1000 is awesome for 140 bucks, can get through all stages . this is me today, sry for the blurple . Im testing a Mars Hydro ts1000 & a cheap 70$ blurple off Amazon together during flower. Beginning of Week 8 flower on the 23rd Nov. This my first grow and im lovin it. Labor of love, happy growing y'all
