This is not the eaisest to set up . I hope it ends up producing.

found a pic on this site that shows the system I'm trying to set up.
I'll post some pics of my system in the next week or two.(after I get it set up) There's still a lot of work to do.


the 2 liter bottle caps just don't fit in the pvc as discribed in this system.
Blue glue , does not stick to the bottle caps . all my caps leaked where they are glued into the the pvc. ( the caps only fit in about 1/4 inch.)

I've reglued the caps with a multi perpose glue and that seemed to work.

Zandor,
You will find if the plants root system gets too large they will clog the 1" hole you are using as a drain
The directions for this system called for a 1/2 " hole drilled into the bottle caps. I went back and drilled a 3/4 " hole in the caps.
I'm also going to add a extra overflo line to this system.

Its a lot of work to set up a good system but give me some time and I hope to post great pics.
rockon696 Reviewed by rockon696 on . ebb and flow I want to set up my first hydro system, but befor i do I want to have everything on paper, ( blueprint) before I start the set-up. The system below is what i'm planning. it's a 11 plant system using 2 liter bottles. I have a few ?'s. 1- What is the best medium for this system? 2-I'm thinking about using clay pebbles, are the clay pebbles fine or should I mix in perlite? 3- If I only use the clay pebbles, how many times a day should I flood the system and for how long? 4- If I would Rating: 5
