I have a pump on the bottom of one side of a 45 liter (12 gallon?) rubbermaid bin the hose goes to the top of the other side. I also have 2 air stones, is the pump overkill? do the stones move the water enough? I fear the magnets in the turbine thing will suck up all the iron.

I figure there is good bacteria in the roots excel, combined with a zyme product would it be enough? Or should I also be brewing tea? is it worth it at that point?

im about a 5 weeks into veg in hydro DWC, 80% of the plant went super light green, probably N lockout due to me not calibrating my ph meter so I put in some N product, I fixed the PH. How long should it take for a healthy green to come back?

I know this isn't the smoking subforum but I need a definitive answer on this once and for all! I used to not pay attention to how I breathed, sometimes I would get very nauseous after a session (especially with hash). Then I started thinking hey maybe I'm breathing into my stomach and I...

DWC setup. I need to triple check my thermometer to make sure it's kosher, but so far the frozen bottle method is super effective. I'm getting between 62 and 65 degrees on my 50 liter res. Without the bottle it can go up to almost 70, my iceprobe can keep it at 68-69, but I don't like it...

I read somewhere that said not to add AN Bud Candy, or even molasses for that matter, into a DWC setup, but it didn't explain why. I tried to search for similar threads, but I haven't found anything specific. Does anyone have any experience with this? Why would it matter? brown slime?

El chepo garden hose, that's brand new that I have lying around, Can I use it safely with my nutrient solution? Thanks
