Gotcha- I've only been doing this a couple years following through my predecessors direction, I'm just continuing to do what works I guess. Someday I'll experiment but it's hard to fix what isn't broken. Might be a little more expensive with liquid but I just buy it bulk to bring down the per gallon price. Tough to beat 300 bucks for 3 rooms for three monthslol thats the problem.. the newer LEDs are way more efficient watt 4 watt
I can feel that.. I use hot water to turn however much powder into a concentrated liquid and then add that to however much nutrient mix I need so its essentially adding liquid to liquid.
