How big is that pool, how much soil did you use, what are the black pipes doing, what is that device or metal box on the pool surface? What is SIP?
Hey Man! If you look back a page or 2 there’s a post showing the construction. It holds about 90 gal of soil, 35 gallons of water below that. SIP means sub-irrigated planter. The irrigation pipe is packed with soil and wicks the water up as the plants use it. Currently the plants are in a circle around vertical hid bulbs and mix of cmh and 1k hps. The box on the bottom is a box fan blowing up towards the bulb. It’s a strange setup I guess!
