Yup pressure fit.
I havet run into a pump yet that will push apart pipes tapped together hard
I use 3% H2o2. 15ml of 29% per gal may be a bit aggressive. Its like soup....you can always add, but once its in there...its in there.
oops I think I am confusing you guys lol.
100ml of 29% makes 1000ml of 3% of which I added 15ml/L vs Your 10ml/L. 88ml/L is used for disease treatment from the grow bibles.
Thanks for the tips!
When I was looking to buy buckets at $14 a piece + lids, I was at my lowes doing some pre-plumbing idea shopping and they had these 12 gal strong boxes on clearance for $2.50!! ( nI remembered you suggested going with totes) So i jumped on that and bought all they had, which was the last stock in the city apparently. The really awesome part is the lids are are black and light proof! I just threw on a very light coating of white plastic paint to have reflection and to keep the tubs just that little bit cooler!
With the spray bar, I experimented with elbow, spray bar and even a couple of T's and found that the elbow with the barb on one end and the thread on the other side ( not the barb x barb) created a TON more mixing and bubbles, its spraying down pretty good. I actually keep it facing to the side a bit to create even more turbulence. The threaded end acts differently and seems to "hollow" the stream and adds that much extra. I could have 5 air stones in there and it wouldn't do as good as this is doing, I am going to try different elbows now, like one that goes 3/4 to 1" or something.
Water agitation is great but surface area disruption and flooming rule lol
I like to use tees that are as big as possible
Causes the water to flume out the sides in a big sheet gaining surface area before it crashes and causes suface disruption
Try a 1/2 or 3/4 to 11/2 on the tee sides
i built my rdwc with some 3/4 pvc end caps( the semi round kind, drilled about 10 holes of really small holes) kinda like a kitchen faucet sprayer
that sprayed into 27 gal totes.. a waterfall of any kind is way better than any air stone/air pump
Thats the word..Flooming! when it crashes into the water it creates a whole lot of movement and bubbles.
No flooming means when your breaking the surface tension of the water just enough to see it raise like a bulbble
You got more waterfall and surface agitation then true flooming
But i use the term flooming in the sense that i make sheets of water .which is more surface area so i might have been wrong in describing it that way
Looking good 16 hours later. I might have saw some very small build up on the rez pvc end but everything else looks sparkling. I think the roughed ends on the pipes may be allow stuff to "hang" on and grow? similar to what i found on the air stones. I used sandpaper to bevel the ends a bit cause i used uniseals and it made it easier to push in without any damage to the seal.
I' start my journal and start posting there tonight.
the normal elbows make more of a solid stream. the threaded end which is slightly bigger tends to cause it to spread or flare and has more air mixed before it even hits the water.
Wonder if i take PVC and cut a long slit in it to make a sheet, it wont make more bubbles but more surace is hitting? its so hard without a DO meter cause the bubbles make you think its doing something more lol
You can get creative and make the bar go across the whole res
And if you can make a thin enogh cut so that water will"stack" up causing it to sheet the hole way.
Just be careful slitting pipe whatch your fingers and use a clamp
Alright so I am looking at them today and see a thin layer of slime developing on the roots, and there seems to be a slight brown tinge also on some roots. Looking at the bottom of a few I see slime building within the net pot.
Not sure what to do anymore other than maybe ditching the RDWC this run and try to put these into ProMix and go my usual route and start again with new plants next season. Or to try the earth worm tea that Heisenberg has recommended?. of course after letting what ever H2O2 in the system neutralize.
Maybe my H2O2 mix is not strong enough? maybe I should go with the 88ml/gal that Jorge recommends?
Sorry I keep saying Jorge Cervantes when I mean to say Ed Rosenthal.
