We are just using lettuce and basil as test applications because its an easy test subject. The system was designed for applications such as growing Nocotiana Benthamiana for manufacturing recombinant protiens used in cancer treatments, commercial medical cannanbis and other high value plant species. Don't assume we did all this just to grow lettuce.
Gen two testing starting soon
In a cloner.
i hope you problems dont apply to me then
You will not have any better results. Question is how exactly will one mist be better than the rest in penetration the root ball? Never going to happen. As soon as you get those pretty fuzzy roots that's all you will get the plant shuts down growing up top and the roots are screaming feed me. HPA is not and will never be meant for MJ.. Roots are to big been there done that. Have you ever seen pics of a successful HPA grow? Lots of pictures of roots but the plant looks like crap and produce less fact. Spend your money on a iwaki 30 or 70 rz pump depending on how many sprayers you want get a chiller and some 3 way valves and do a recirculating system. Just remember everyone who has done hpa blame there nozzles for there crappie grow and think I need to get more expensive nozzles last I looked they are saying 200 buxs per nozzle to make it work lol. Misery loves company... One last thing I was running my misters at 150 psi and still could not penetrate root mass. Anything higher and you will be damaging your roots. Also i was running 32 solenoid valves using 25 gallon containers. Wish you all the best.
i think if it came down to that i would just stick to drain to waste coco coir.
Would be interested in your results like I mentioned the wall comes around day 45-60
Here`s a second of AA mist at 30psi, it will penetrate a root ball without causing any damage. Its nothing like the mist you get from a hydraulic at 150psi.
You just need to have proper room for the roots to grow and proper nozzle location. If you place the nozzles pointing up into the roots, the roots fan out more giving better penetration. You also need a deeper root chamber, at least 24". For Cannabis, you'd simply have two levels of nozzles for maximum coverage.
hey hammer ive got to retract what i said. i was thinking and i did see a successful hpa grow. it was in the tricky 2011 thread. i cant remember their screen name but they grew SOG, in multiple rubbermaids and used red teffen cloudtops. he showed pictures of what he was doing and claimed he broke the 1.0 gram per watt mark. i think that is success
Now imagine something like what we've been working on with a root chamber double the volume and having two levels of manifolds. That's going to be our commercial SOG system.
I think this is the big conundrum with HPA, and even AA. So many have tried and failed, myself included. Especially when trying for long veg times. You have to get everything right. I have yet to prove it, but overwatering in the beginning, I think is the key. Get the tap roots to shoot down, provided you've given them adequate room to do so, and work the fuzz from the bottom. Tree farmer says that if your roots are growing into a ball, you're doing something wrong. Perhaps too fine of mist, not sure. It's made me so crazy I needed a break from it. Was really hoping that this shit would be common knowledge by now, and anybody who's anybody could do it, lol. Good luck sir!
Maybe that's the mistake people are making. If your growing large plants, you'll have a large root system to deal with. I would think with a proper SOG you wouldn't need a long veg time.
Timming and alternating solenoid firing. They don't all have to go off at the same time.
I'm starting to notice a trend here. It doesn't matter what we do, you always seem to think it's a bad idea or have some negative comment.
I'm glad to hear you've already conducted this R&D, maybe we will have better luck.
