JPLord Round 2 GDP MPB grow

[aleYarok]

someone should meld a UC and MPB together....

basically a UC, with a bigger res, with separate feeds and drains for each buckets
drains would be like an 1" under water level and no waterfall into res, just uniseal, so the drain is always full of water.

1/2 hp ..my temps are fine. ran the hydrofungi and still got it in 1 tub(out of 6). i think i had better luck runnin the mild bleach(1ml/10gl). i think my prob was top-feed related...now im vegging in bubble buckets and think this will have many benefits, besides no topfeed at any point. better rootmass and transition vs. straight cubes going into the tubs.

absolutely! lots of DO brewin in there...speakin of which is i'm really lookin to ditch the 4 12" stones in each tub. what other gadgets are any of u using lately?

 

[4.D.]

if the drains are the problem w/ the mpb's...any ideas on modifying the system? I'm on my 3rd run now... first 2 runs had the rot in one tub. not giving up though, i'm pretty sure a problem free mpb would outperform a UC.

Im pretty sure the problem free MPB is the UC.

Why have a drain at all?

Most people rocking the UC have a top off res. Check Jack and Bens threads. They have huge top of res' hooked up to a float valve, making the system nearly fool proof. No drain so no need for check valves or gate valves. No need to raise the system. If a pump fails the UC is still full of water.

What is the difference besides the drain line?

I think that high levels of DO and nutrient flow are the key components to both systems. I think that with the same pump UC has a stronger flow with the same size pump because of the way the pump feeds. And with 2" or 3" pvc feeding the UC, there is a lot less resistance than the 1/2" feed for the MPB.

Well,
As far as feed line on mine, I use 1.25 pipe that has a 1" riser, that necks down to a .75 for the last few inches.

For extra DO I added a Venturi onto my circulation pump for an extra dose of oxygen. My trick of the day.

I don't think any system if problem free, but the uc has been proven safer, and you actually have support as well.

Thanks trich. You undoubtedly have the cleanest mpb setup I have ever seen. Your growroom reminds me of Heaths Flooded Tube grow. one of my personal favorites.

 

[TrichromeFan]

No prob,
I am nowhere near mr. Heath's level. He has got to be one of the most ingenious growers out there. He makes me want to do a vertical grow pretty damn bad.

the point would be each bucket has its own feed and drains, to and from the res.... instead of the passing through bucket to bucket.

like i said it would be more like a UC. it wouldnt be rasied. it woudlnt need gravity to drain. and it would always be full of water like a uc. no check valve. u can even add a top of res like the uc.

I hear ya, one thing that I really liked about dd's setup was the quick release fittings allowing you to isolate and remove any buckets with any problems.

So I got a COCO log going in the coco fourm so stop by and see whats up.

I love your setup it is so clean I would put in some clean outs so you can scrub the pipes with a brush to get it all clean. Do you have a end cap if so you could take it off and spray the inside with a power washer this may work.

I just saw the new UC pro series has clean outs, your and JK were ahead of the game with that idea :) :joint:
