I learned alot with my first batch (currently in second week of flower), and as duch, Im thinking on making a few changes for the second go around. This is the setup I’m considering:
Light: 2x 2000W Bestva DC full spectrum LED (396 true watt from wall (792 total))
RDWC: 9 plants, head and tail buckets. Planning on using the tail bucket as a larger reservoir, about 20gal. Total operating volume: ~65 gal
Air: 190 CFM exhaust fan, humidifier in tent, window AC unit cooling surrounding room
Oxygen: 2x 950gph air pumps, one 5" circular airstone per bucket
Flow: 1333gph submersible water pump dialed down to suit
Water temp: 1/13hp in-line aquarium chiller
General hydroponics nutrients.
Blue lab automatic pH regulator
I’m still deciding between setting up with flexible tubing vs 2" pvc. Flexible tubing would allow alot more leeway with modification of the system in terms of how far the plants are from each other, but would also create more noise with the water flowing through the tubing instead of PVC. The hope is to rig up a CO2 emitter for the flowering period as well.
Please let me know if I missed anything, and I’d love to hear your ideas for any modifications!
