Hey guys! Newbie here.. grew 3 cycles of soil in a couple of 4x4 tents with hps 1000w setup previously and I’m now interested in building this race car system! A drain to waste HPA system. Been trying to find HPA threads here but haven’t had any luck with the details I’m looking for. Was hoping to ask a few questions as I realised aeroponics involves a lot of electrical works and fluid dynamics ...
1. Will the pressure of the system be a problem if we have different diameters of tubing through out? Tubing starts out with OD of 1/4 inch which then transitions to 3/8 inch tubing? This is due to my diaphragm pump being 1/4 inch sizing but the Tefen Nozzle Adapter Tees are in 3/8 inch sizing.
2. I keep seeing “Tefen” for mist nozzles. Is this the gold standard brand? There are different specs for Tefen nozzles as shown in the tips. “0.7 - 80 -F” or “22/20” and “21/0.5” What are these specs for? Any recommendations on where to buy parts for Tefen?
3. Heat being a major factor for the nutrient delivery for the roots, are there any problems with the heat generated from the Solenoids valves and Pump? I read that solenoid valves can get very hot and it needs a heat switch. People have been suggesting to insulate the tubings which I find redundant in theory.
4. Also, how do you compute for the maximum distance for the tubing? (Does adding an accumulator tank increase distance of tubing?)
Hoping the pros can shed some light on these concerns!
Purchased Parts List for an 8x 5-Gallon Bucket system:
Aquatec 8800
Solenoid Valves 24v
Aquatec Pressure Switches 100psi
Check valves
Accumulator tank 6 gal
Pressure gauge
Fittings and tubings 1/4 and 1/8
