Thanks for dropping by.

Perhaps you could help me on the 2 types of fog though. How often are you planning on running the nozzles? It kinda seems like they would wash down the roots, thus defeating the purpose of the dry fog. I would expect no real improvement in the amount of fine root hairs you would normally get with dry fog, and I thought wet fogs produced roughly the same results as spraying. The whole point of fogging is to produce 5 micron droplets so that the roots get loads of air with their food and drink.

Also my understanding about misting and pumps is that for a true mist (something like 50 micron droplets) you'll need a 1000 psi, not 150. That and clogging is why I gave it up.

I'm new to fog research, so please correct me where I'm wrong.
