Its best to buy a footpump and a digital pressure gauge so you can check and adjust the precharge from time to time.
Apart from the hassle of unhooking the tank and carting it off to the garage once a week just to check the precharge, i wouldn`t trust a garage gauge to be anywhere near accurate, hence the need for a digital.
And Jk in earlier posts u were saying with Hp system hardest part is the root growth being so fast and so much what are you and anyone else who wants to add..using as root chambers? Seen the 5 gal pals seem to fill rite up. Anyone doing any crazy PVC customs? Just wondering what's good what's not. I'm thinking a PVC would be nice but thinking it has to be big, thanks guys the more I know less I can f-up or at least not as bad
i like my lp 36 gal containers, they in 5 years will pump out much more weight then hp systems.
why?
Still here JG, just been busting my ass for the last week trying to get my room ready and put together this fucking beast of a system..............basically trying to emulate the box from the thread linked earlier (post #355, "Mr. Mister") - his craft skills are 100x better than mine, but I'm doing my best.
Also can't for the life of me source a box to hold this timer in.........it's 4.5" deep, and it seems they don't make boxes that big - looked all over the Grainger website for the one that Cavadge used, can't find it..............if anyone can find that box, I'd be much obliged.
Pressure switch/pump combo is wired, timer is wired, just need to run a wire to a junction box which will feed all four solenoids.
Bottom "row" (15 misters) is done; will finish the top row as soon as UPS gets here with my John Guest fittings (broke one of them while installing, I'm that much of a beast :) ).
As you can see, put a screen over each mister to prevent roots from covering it; that's a "sun screen" (not an insect screen), so I'd highly doubt any roots can get through that sucker (insect screen they could go right through).
Got a Black and Decker air compressor for $60 with a digital gauge that can go up to 120PSI.
Also am building my box (almost, save for tubing and some electrical holes) completely sealed (not sealed, but no designed openings for heat to escape) - don't think the pump will run for that long anyways, and I HIGHLY doubt heat would be a problem - there's gaps anyway from my shoddy craftsmanship :)
Was pretty surprised at how quiet the pump was when I tested to see if my wiring job on the pressure switch was right (it was) - granted, it was sitting on my carpet with no water, but it was MUCH quieter than I'd expected.
Ummmmmm, I guess that's about it for now...........realistically, early next week I hope to have plants in the system - will have it setup by tomorrow (Sunday at the latest) and running for a couple of days before I put anything living in there.
Any comments/questions, please do ask/tell - lemme know if you see anything that's gonna cause instant death - thanks :)
John, another question - is that 98PSI pressure the "ending" pressure that we want to shoot for, or is that the pressure to disconnect the air hose at?
I realize that when I undo the air hose I lose anywhere from 3-5PSI in the process, so should I precharge to 101-103PSI to account for that or am I really shooting for the 93-95PSI ending pressure?
Thanks bro.
