Are you talking about the green tub outside the tent? That's the 30 gal reservoir I decided to use. Easier to acquire and cheaper than a 30 gal food grade drum. When I bought the pond pump I didn't realize it had a diverter valve so I don't really need to move the rez to empty and refresh. Just attach a hose to the other port, turn the diverter knob and pump out the old solution into the vegetable garden so that the veggies get a shot of fertilizer.Is that a mono tub i see?
Need to order one of these to help keep the nutrient solution fresh and aeriated. I'm too lazy to drag out my water chiller and air stones, plus I think it'll be a bit of overkill, so this should work almost as well as far as oxygenating the water and keeping the solution organics mixed in the water and not sitting on the bottom of the reservoir.
I had mentioned that the two plants I had moved outside were girls since they were both showing bract calyxs but one turned out to be a boy so.....yippeee.....more GG4 seeds to keep for future grows or to develop moms with. You can also see how the phenotype, left on its own without training, stretches! The girl is already showing preflower pistils so it looks like flip will be relatively speedy!!
