latewood I'm not sure what you meant about the coco mat. I was thinking about putting a coco mat on the bottom to try and stop any roots from trying to go into the drain, or will the roots grow right thru it I don't know shit about coco mats. I buy my drains and plumbing tonight will have some pics up this weekend.;)
as far as I know...coco mats are used alot in ebb and flow to give the roots something to travel in...so to speak. (hell, I wish a coco mat/ebb and flow, experienced grower would chime in) The idea of using a cocmat to help in your situation is purely speculation...the idea here is good, but will be an experiment the entire community can follow. Let me know if you need help, I am watching thread...later lw
The coco mat can help with a few things, one, helps keep a little moisture on the bottom of the table because some of the coco cubes can dry out fairly quickly, also it does give the roots something to grow down into which unlike the hydro rocks, will protect the roots from light and help to stop roots from clogging up any drain pipes. One thing i've notice from another grower is that with the 2 sizes of thickness which the mats usually come in, the thin one is as good as the thicker one and cheeper.

Here are my pics.
Totes: $20
Plumbing: $60
Frame: Free, I used galvinized steel we had laying around at work
heres the rest of the pics, the hole you see on the cover is going to be plumbed from a 50 gallon drum so I can pre mix my nutrients in large qauntities.
Wow you are gonna need lots of nutrients...how often do you plan to change that system.
What do you mean "change the system"? If you mean the nutrient solution it will be about once a week.
Wow thats a big rig :D Can't wait to see it progress :)
i like i like.....thats going to produce some monsters if enough wattage is used and spread out ~ garanteed....but i would suggest putting a 2nd nutrient resevoir there, drill a hole in the side but at the bottom of 2 nutrient tubs, then push a hose threw with a rubber seal or sealant (the water will automatically level out to the same level in each of the 2 tubs) so if ones almost full, the other one will be too ;)
This will give you 120-160 litres there to play with instead of just 60-80ltr (depending on the size of your tubs of course)....
mine is a 60ltr tub and i have to top it up every 4-5 days for just 4 plants.
Anyway, keep us updated, and keep the pics commin, i wanna see this grow, its intreaged me. :)
Take care now, Peace!
Bliss.
NOw all you have to do, is keep checking your ph and ppm once you fill the rez...top off with water a couple times before you changeout nutes...I don't follow the regimen in a rez like this as much...I let the plants drink the solution...top-off, top-off...then when solution level is just over the pump...I put in fresh batch of nutes...most of the time, I just mix 5 gallons to 10 gallons at a time. I do not always fill rez. later.
