ebb & flow
 

Hi Ron,

My wife and I are planning to build our first hydroponics greenhouse. We are curious which would be best an ebb & flow to
maximize space availability or the PVC type system you seem to like? We thought we could grow more in the ebb and flow
type system. We are going to concentrate on lettuce and herbs.

P.S. Great website!!

Thanks, Carey and Kristi Clark

Because I only use grow rocks I would have to use to much to fill troughs or tubs or gutters and it would take a bigger nutrient holding tank to fill the system.
With the 2 liter bottle system each plant only has what it needs.
I have systems that are right next to each other for small plants and sense the plants are removable I can move them to a larger system as they grow.
