Nothing huh? Well... I'm about to start fucking around with this shit again, and info seems to be a wee bit thin at the moment... I ended up here (again) from the first few google links so here goes: Don't think you can actually buy a PUR meter, it's just more of a concept... Near as I can...

Thanks bud :-)

Hey man... Been crazy busy for the last few weeks. But I put up a small private album... Figured I owed a few of the folks that had helped inspire me a peek at whats been goin on :-)

I think it was T.F. that told me roots will not grow through a silk screen, but water will pass freely...

Damn guys... I get busy and don't check in and this thread is 79 pages??? So... I'm still back on page 40 catching up, but I just wanted to let ya'll know I wasn't dead or anything :-) Can't say things are going fantastic, I had to slap together a quick and dirty DWC for the girls... And PH...

Indeed... Although we tend to break the distinction down between high pressure aero (HP) generally 80psi and up, low pressure aero (LP) generally cutting off around 40 psi... And the other system designs like bubbleponics and such... So many good system designs... No sense in knocking anyone's...

Nice... Water softener pellets right?

Rapid rooter grow plugs apparently... Recycled rubber my ass... And at $12 for a bag of 50 I got ripped off :-0

I guess there is no real reason I can't have both set up... I have enough leftover parts at this point... As for the length I would just run them in the bottom through grommets. I've had a bucket filled with water for days with the level several inches over the nozzles and got no leaks. Had...

Good call man... I know vdub well... I actually use it to recombine the audio in all those vids so I don't have re rerender it in after effects... I had actually planned to make the time code in the corner go red when it was running, but I got lazy :-) Need to get me a graduated cylinder too...

New vid up: http://www.youtube.com/watch?v=_S7hpV7BBm4 Captions pretty much cover it, but I added a prime command that runs the sprayers for 10 seconds when the program first starts to flush all the air out of the lines. Dropped the spray time to 0.5 sec (still running a quick off time for the...

Trust me on this one, the filter can be positioned in any orientation. Generally they do go up and down though it's not required. There is enough of a seal between the inside and outside of the element that nothing is getting past. Think about it, if it's going into system that's nominally...

Well the 140 was measured with a gauge from harbor freight too, so maybe that's their legendary quality. I'll play around with things a bit, I can tweek the peak-hold feature on the electron gauge... I might have just been seeing a spike before.... But one way or the other I'm getting to the...

Thanks man! I figured it should be on the output, the pump is not self priming so I didn't think it would be able to start up with the strainer on that side... The system is going to be drain to waste so there really won't be anything worthy of filtration going into the pump... It's really...

Wow man, congratulations! That's no small feat, I'm glad your feeling good and things are going okay. Enjoy the concert and take your time planning what your going to do. T.M.H.

Well now here is an unfortunate supprise... I'm only seeing about 60psi at the manifold even with the return almost all the way closed! I tried bypassing the filter and that didn't do anything (which is good in a way... nice to know that it's not really adding any losses)... But still... I can't...

Good to know :-) I'm in the process of hooking up the pressure sensor now now... Should have my computer set up down there by the end of the day too... So I expect to be able to get some more hard info. I have a second sensor head so I'm going to sub that in for one of the nozzles and take a...

Thanks man, I had a good time making it... Just wish my camera was a bit better. You math checks :-) I came up with 32 OZ/min or ~ .53 OZ/sec I seem to recall that my solenoids were rated at 0.1sec open/close time (Though I can't seem to verify this now)... Which would mean that the absolute...

Sadly it was brass... The least expensive SS one I could find was around $100 http://www.mcmaster.com/ #98905k15 There is also the following: #5784T12 Nickle plated brass I figured I would just put it at a high point in the system or something similar... But I like your idea of the check...

lol!!!!!!! just add the pressure refief valve and sleep well. Not quite the same thing... But I saw a welding cylinder go through I cinder blow wall once in shop class.... Someone had not chained it up properly... And the place was a mess so somehow the thing fell and the regulator snapped off...
