Media free net pot E&F/F&D?

Hey all.

Noob here. I know someone is doing it this way, but I can't find an example doing a forum search.

What I'm thinking about is a net pot setup without any media. It would only be using the STG 2" rooting cubes in 2" net pots (so not actually 100% media free if you consider the STG rooting cube). These would be placed into holes cut out of plexiglass over a E&F table. Instead of Aero, it would use E&F/F&D (Ebb&Flow/Flood&Drain).

I want to save the cost of buying bunches of media all the time, and having to dispose of it. I know I'll loose that buffer media provides, but am willing to take that risk. Essentially, this will be a F&D version of a NFT setup, or a sprayerless Aero in a flood tray. The advantages would be no emitters or spaghetti tubes to clean all the time, and less media to fiddle with. Easy and simple is always better. If it's also cheaper, then that's just icing on the cake.


Questions for anyone who is actually doing it this way:

*Do you use a thin layer of media or media mat on the bottom of your tray? I think this could add back some buffer, and provide something for the roots to rest on if they don't like sitting on the always wet bottom of tray without adding much media.

*What sort of watering time cycle do you run? I'm thinking of letting the pump run constantly with a bell siphon during daylight, and turning it off with a timer during lights out. In Aquaponics, the pumps seem to last longer without constant starts and stops. Rez water will be well aerated, so I don't see much dif from a bubbleponics/floating raft system other than the F&D cycle. I just can't see leaving the roots in water 24/7. I know it works, but can't bring myself to trying it.


My experience is mostly in Aquaponics these days, but this system will be a Canna nute/35% H202 setup. No magic sauces or organic nutes (Al B Fuct "Lazy Stoner" K.I.S.S. style).

Also, is anybody using the STG 2" rooting plugs with 2" net pots in a Aerocloner? I'm thinking about building one for the clones. No nutes in cloner, so no clogged emitters.

This will be a SOG. No veg. 3' tall plants. Support steaks if needed.

I wouldn't be able to move plants around in this system, but I couldn't care less about that. If you've done your job, and have good light, you shouldn't have to move them around. I see no advantage in taking a plant that is doing great, and putting it into a spot where it won't do as good. 1+1=2 / 2-1=1. It should cancel itself out in the end anyway. So why bother with it?

I've decided to just run ebb & Flow for the cloner. I don't see anyone using the STG 2" rooting plugs with 2" net pots in a Aerocloner. I'm sure it would work, but I may as well just run a E&F. Less plumbing that way, and no chance of clogged emitters.

I don't think I'm trying to reinvent a wheel here. Just simplify a rocket ship. Succinctly put, I want the advantages of NFT and Aero, with the simplicity of F&D, without all the mess and cost of using a lot of media.
