They're just an OEM reseller. Get you a 100 PSI Shurflo, or a 200 PSI Aquatec and some Teffen nozzles. Solenoids come in all flavors.
Nothing wrong with Netafim's, the Teffens will get you about 10-15 micron finer mist though. Netafim's are rated at 65 micron and the Teffens 55 microns. I think what's probably more important is how the plant grows, than how attractive the nozzle throws the mist.
Here`s the roots from a high flowrate netafim quad (4x grey 7.5LPH), 50psi with no adv in a cramped chamber that were seriously overmisted. Nowhere near optimum but the roots still look better than the lettuce which is a bit wispy in comparison.
"Wispy" roots are exactly what we are striving for.
They wouldn't be "wispy" if that was the case.
We have, that's why we also have a 24" deep tray. Our design is intended to reduce the roots tendency to run to the bottom, but instead form "wispy" roots.
do you ever measure the amount of usable light using a par meter. i would be interested to know what intensities your using.
that pod sort of looks like the work of treefarmer, is it? nice to see the netafims can get the job done
PAR is meaningless when comparing different lighting technologies unless you know the exact spectral output and can measure spectrums independently. Even comparing PAR from a 'white LED' grow to a 'Red/Blue LED' grow doesn't work.
im not trying to compare different lighting technologys. im only interested in learning how many photons in the 400-700nm range are striking his growing surface.
Seems your goal is to negate half your root system. Its clear to anyone looking at the pic the lower root growth is a lot more dense compared to the upper roots. Notice how they resemble a ball? The lower roots are receiving more mist and grow better, the upper roots suffer as a result. The plant focuses on the lower roots because they are the most viable and that compounds the mist blocking issue .You`ll end up with an impenetrable barrier and a shedload of issues.
As opposed to them running to the bottom and bunching up there? We found placing the nozzles under the roots actually reduced the size of the root mass some 20%. We started out doing tests with horizontal nozzle placement like everyone else. We've probably tested a dozen different nozzles and half as many placement locations. We've been at this for 3 years now. We even played around with AAA. I still have a 2HP medical grade air compressor collecting dust. We've been improving our current method for the past 8 months and have increased grams per watt considerably from when we first started.
