I know hydroponics is without soil, but I use soil. If I have a drip system at the base of the plant roots for a 1.25mx1.25m soilbed with 20 plants SoG. With a drainage at the bottom of the soil bed leads back down to the resevoir.

Is this a workable system or any forseen problems? I would need a resevoir, pump, filter and 20 drippers... anything else?

If i understand correctly what u are saying, you will drain the excess water that goes through the dirt into the res????LOOOLLLLL that would an interesting setup to folow...

“When you smoke the herb, it reveals you to yourself.”

dont know about interesting!
the better option would be a simple irigation with drippers set at two litres an hour, begin with one minute every 3 hrs or so, reducing the times between feeds as the plant grows,in the end you wouldnt want to put more than one minute every hour!thats eighteen mins after an 18 hr cycle that makes 750 ml a day more than enpough!

the fear is over watering, there is a way to flood soil completely without over watering, its more a composite mix though, in fact there is one comercially available terahydro i think its called!,there are also batery powered motors that feed measured doses of nutes to each feed
and can be set to water once twice or four times a day, automated soil grows have been here for a while,
as for catching the draining water i soil ,,,,bad idea there shouldnt be any water out of the bottom of a pot when drip fed!, unless you over watering!

have fun!
welcome to the world of endless possibilities,,,,,hydroponics!

if ur going to the trouble of setting up a drip system with drainage and res, just do a hydro grow....

Yeah, I'm starting to see that a simple irrigation system will be more than enough. Tetrahydroponics, sounds cool.

Do you think a soil medium of

25% perlite
25% fox farm light warrior aeroponic medium (layered at bottom for best drainage)
50% fox farm ocean forrest.

would work alright? I only ask because I already have all of those products and it'd be easy.

look up Terraponics and see it has nearly all the mediums used mixed together!, including coco and vermiculite as well as the above, try and make your soil medium as soil free as possible , while leaving the good properties of soil in there the other mediums will allow for good drainage and oxygen retention.
hey give it a go if ya wanna experiment ,
but ya may concider uasing a varieing mix in each pot, labeling them, and keeping a record of the mix for when the crop is done, so you can duplicate the "right " one again, for the following crops!
alternativly, spend some money and either go hydro!, or buy the Terraponics from the net!. at least check it out on the net for its ingreidients, and properties!,,,,,its actually called terraponics, and the web page is www.terraponicseurope.com it contains 23 propritary ingredients, including three soils ,leonardite, humic and vulvic acids humic peat,organic rock, volcanic rock. vermiculite and perlite, etc etc etc

check out there web page!

welcome to the world of endless posibilitoes,,,,,hydroponics!

dude, you shouldn't reuse water when using soil because shit'll flow into your pump and clog that or your drip emitters. I tried that with cocogro and my pump got fucked up.
