So this is my indoor grow area in a 10x20 shed, half is partitioned into grow area and lined in insulation board. And I only grow on one side of the shed, so realistically it’s a 10 ft x 3 ft grow.
It’s a recirculating DWC system consisting of 4 totes and an additional tote as a sump.
Each tote has a standpipe connected to a common drain to sump. The standpipes ensure a consistent water level in each tote. Which provides consistent water level, plenty of air to roots, and roots being less likely to block pipes. Pump in the sump delivers water to each tote at a rate of about 50 GPH thru irrigation piping, which then overflows back to the sump via standpipe and gravity.
Have two lights both full spectrum LED’s. One 400w and the other 200w.
Box fan in the roof corner for air circ. Fresh air is pulled in from outside, where I happen to have my rabbit hutches attached to the shed. (Little furry CO2 providers)
Airstones in each tote, sump, water reservoir, etc
Running a room air conditioner and dehumidifier vented outside to keep temps at a reasonable level.
A/C and dehumidifier both drain to 55 gallon drum in the corner. I use a mixture of my well water (which is very high PH) and the condensate water (which is very low PH) to maintain PH.
Total system water is about 60 gallons. Like to keep nutrient Ppm’s around 600 during veg, 800 ish during flower. General hydro trio with a bit of cal mag and tiny amount of silica.
Using inside tent to dry / grow out cuttings for friends / transplant to outdoor grow (aquaponics, 5 gal buckets etc)
It’s really almost identical to my outdoor aquaponic setup, except with a standing water level versus using an auto siphon system.
Also have a couple Gnomes keepin an eye on things.
Roots in the bubble bath.
Standpipe
