Use the shortest spray time you can get away with. A lateral can have millions of roothairs. They are short lived so the old ones are constantly replaced by new. They grow at around 1 micron per minute, about 1/16" per day.

Laterals are not the same as root hairs. Zoom the 2nd pic and you can see the beginnings of root hair development but its being hampered by too much water. A zoomed slice of the roots from the 2nd pic is on the left in the pic below. If you compare them to the "too wet" example on the right you...

If the roots from the cloner wont fit in the netpot you could cut the bottom off or simply use a collar without a netpot. A hammock wont prevent the roots from reaching the UC, they`ll grow through it or around it.

I guess you were misting the hell out of everything? ;) Aim for a light film of condensation on the netpot, if you have water streaming off..its too much.

Too wet for pure aero but it`ll be fine for hybrid UC.

To get the 80-120 swing you`ll need an adjustable pressure switch capable of a 40psi differential. You also need to set the tank air precharge to 78psi. Be sure to check what the safe working pressure of the tank is ;) The solenoid should be controlled by a cycle timer. The pump and pressure...

My accumulators are my reservoirs which hold 40Lof nutes each. Ever tried to oxygenate nutes when they are under 80-145psi of pressure inside a tank? its good that its not necessary ;)

I`m amazed your not having to replace the nozzles daily ;) Here`s a 0.3mm brass patio nozzle at 10bar (145psi), they clog at the drop of a hat

I use homebrew nutes and run sterile drain to waste. With organics every surface in the system will become home to bacteria colonies will ultimately slew off and cause problems. You could run organic with syphon fed AA because theres less than a foot of pipework involved and its not as easy to...

I have a hpa system that runs on a 20w solar charger and 7AH SLA battery, its tough to get much more power efficient ;) $600 for an inline filter? You have more money than sense, a 250 mesh inline filter capable of 14 bar pressure and a flowrate of 80-100LPM costs less than $30 here ;)

I ran a 1500L (5m x 0.6m) outdoor hpa chamber with an aquatec 6800 which put out about 360ml/min ;) The $1056 pump (60LPM) would be good for 73ft x 73ft of planting area which is almost 1300 x 200L barrels. Sledge hammer and nut comes to mind ;)

You dont need a $1000 pump for hpa ;)

As dstroy said, it depends on the nozzle. Assuming an equal orifice size, an impingement nozzle is less likely to clog because it consists of a hole that produces a jet of water that is converted into droplets as it impacts on the pin. Standard nozzles typically turn the flow through 90 degrees...

A little moisture on the brass body of the nozzle wont cause any issues, unless your using neat nitric acid ;) Running high pressure water through a brass orifice will erode it pretty rapidly hence they use stainless steel for the core because its harder wearing. All nozzles are subject to...

The brass patio misting nozzles have a stainless steel core and orifice. They are prone to clogging in their normal application which is plain tapwater run to waste. Almost everyone buys those nozzles first because they are cheap and the easiest to find.

That mesh size is ok for most purposes but not those nozzles and a recirculating res ;) Debris is rarely spherical, if a short hair hits the screen head on. it could find its way through.

The fuel filter in the link wont be close to 250-325 mesh. For those nozzles, go for the highest mesh number (smallest micron size) filter you can find and hope for the best.

I`d be looking for something with a 250-325 mesh screen and even that may not be enough. Those nozzles love to clog.

If its a hybrid system you may as well run the nozzles direct from the pump via a cycle timer. You`ll need some decent filtration for those nozzles and plenty of spares ;)

Depends on the chamber dimensions and nozzle spec. In most cases, the mist pattern of the nozzle will dictate where you can put it..
