I do rooting in a homemade abb and flow/nft hybrid set-up
15 minutes on and 1:45 off. watch your hydroton to see if it get's too dry before water cycle. if so, then shorten off time until your medium is almost dry. hope this helps.

p.s. commercial lettuce growers use ebb and flow to root there veggies before placing same in nft or drip for vegging.
latewood Reviewed by latewood on . Cloning in Ebb & Flow System Hi Everyone, Anyone have any experience cloning in an ebb & flow system w/Hydroton? I'm using rapid rooter, Olivia's Gel, Anti Wilt, Reservoir is 3 gal, ph 5.9, ppm 300 Timer is set for 1/2 hour on, 2 hours off. Does this sound correct? Using Floranova w/all enhancements, according to GH schedule Rating: 5
