High Pressure Aeroponics (HPA) Growers Guide

BobS, not sure where my response from yesterday went. I seem to be experiencing problems posting here.

This pic is of a root mass somewhere in mid-late veg. In mid-bloom it was 2-3 times as thick. If I can locate that photo, I will post, as its' fullness expresses what pomp poms look like.

Note that low pressure roots look nothing like this pony tail which tons of lateral roots. The over wetness was resolved after I adjusted the mist heads away from the roots.

In my current grow I am misting for 15-30 seconds (30-40 minute pauses), so even though the first second is not > 50 psi, roughly the point of HPA, by the 2nd second it is, and after that probably pushing 100.

Looks like a pic of my roots in my LP Stinkbud veg unit.

Willie I have one of those too!! Actually, I have that one and the NFT system with the two white PVC fence posts.

2 Important Lessons:

1. HPA is the only method currently available that is capable of producing a root structure that looks like fluffy cotton candy. Imagine how much surface area that provides to an atomized misting of nutrients. This root structure will not develop until/unless the root pod environment is conducive. Too wet prevents the fine root hairs from developing, too dry and the roots die. I have been guilty of trying to get these root hairs too soon by minimizing my wet cycle too soon.

2. When growing from seed (and probably clone) there is a tendency to reduce wet cycles too soon. The lack of adequate root structure will/can stunt plant growth. I have been increasing it due to plant wilt. Currently up to 8 seconds wet ~ 3:15 dry in a 18G pod, but will back it down one second at a time as the roots grow to tennis/softball size mass.
