Definitely agree, starting to lean towards root zone temperature and the nozzles not working as they should/ average dropletsize.

The canopy is getting up to 82f, I figure the chamber is probably 75-80 if I leave the door shut, been leaving it cracked now.

How’s the water temperature?

What was the last change or two? Although I’m guessing you didn’t wait long enough between changes. Before you saw the jump in roots? How many days in, around 21 for example?

Errrr....my ph probe says the current gallon is 81f...

Does HPA have a desired temperature?

keeping around 1-2:30 minutes off, not 10-15 minutes, while they are very young atleast, keeping the nozzles in a good mist/spray pattern.

Proper e.c and not over dosing peroxide or hypo acid too maybe lol.

Only takes a few hours to a day or so, to see changes in these kinds of systems, as the roots are just so exposed/ a lot more vulnerable.

Well I think I read somewhere it's actually a more critical variable unless high o2 levels in the root zone, basically.

That might of been from GPT though.

“The HPA (High-Pressure Aeroponics) method for growing cannabis involves using a nutrient-rich mist to deliver water and nutrients directly to the plant roots. The preferred water droplet temperature in HPA systems typically ranges from 18°C to 22°C (64°F to 72°F). This temperature range helps to optimize nutrient uptake and promotes healthy root development.

Maintaining the water at this temperature can enhance the overall growth and yield of cannabis plants, as it ensures that the roots are not stressed and can efficiently absorb the nutrients provided.”

I just might need to get a chiller lol.

Ideally I'd oxygenate RO water to 20-40 mg/l DO.

Have an accumulator tank, solenoid valves, a bigger pump, and micron mesh filters, run around 100 PSI with 10-40 micron antidrip brass nozzles, a inline micron mesh filters as well down to let's say 50 microns, one grower filters down to 1 micron.

Probably would not even need to do inline uv sterilization with DO that high, and recycle my water in a closed loop system.

Make a root trellis/support structure the root system.

Copper mesh lining in the drains or at the bottom or a little above to stop roots growing down into.

although proper misting cycles and they'll stay in the middle/in the mist/aero zone and not grow down anyways.

Still editing

Needed to put a comprehensive upgrade and parts list up so I'll have it ready
