Conundrum time, would love your guys inputs. orders from pex supply above $300 get free shipping, the 35 gallon tank is 259.95 + $44.14 shipping = $304.09 http://www.pexsupply.com/Amtrol-147N130-THERM-X-TROL-ST-60V-Expansion-Tank-34-Gallon-Volume
The also have some relief valves and regulators that I'm not sure would work in the system but if they do could bump me up past the $300 needed for free shipping.
Relief: http://www.pexsupply.com/Relief-Valves-313000
Regulator: http://www.pexsupply.com/Pressure-Valves-221000
If none of those work then I may be best off going for this 44 gallon for $324.95 that qualifies for free shipping by itself. http://www.pexsupply.com/Amtrol-147N131-THERM-X-TROL-ST-80V-Expansion-Tank-44-Gallon-Volume Thoughts?
AA is the top tier of aero, you have to be very dedicated or slightly crazy to go that route :)
A recent test showed a single AA nozzle can fill a 27gal chamber. The mist contained just under 1ml (0.034 us fl oz) of liquid.
The same coverage with HP would take at least 4 nozzles. To deliver the same amount of liquid they`ll need to be 0.23gph each with a misting duration of 1 second. No run on allowed :)
For four standard 0.8gph nozzles you`d need a misting duration of 0.3 seconds. Its a tall order but doable with the right timer as long as the solenoids are right at the nozzles.
you`d have to have some differential, running 100-102psi with a 34gallon tank gives you all of 0.6gallon before the pump kicks in :)
The regulator keeps everything constant, remembering that aero is all about control.
An AA nozzle is driven by compressed air. If you fire an AA nozzle into a garbage bag, the bag inflates and the mist is evenly distributed by the airstream. A hydraulic nozzle wouldn`t inflate the bag.
Thats right, both air and water are controlled by the solenoids. If you think hp aero is complex you should try this route ;)
The biggest problem is noise, a silent compressor costs silly money and you can`t even store air to run for 24hrs as it takes too much space, a lot more than an accumulator :)
2 plants in a 150L chamber is my limit and its nowhere near a pound. I think you`ll need a fairly long veg and a pretty large tote for that. I`ve never kept the roots off the floor but its worth doing if you can get silkscreen cheap enough.
This is the one I got; not sure what the difference is, but mine was $25 cheaper.
