Thanks for the reply!

Yes, these are going into a dwc system. I used the A-OK plugs (1"x1") with a very light solution of Hormex. The seedlings look good, but just no roots.

I've also noticed that the A-OK plugs are drying out quite a bit over a 24 hour period. I am re-watering them when they are about 80% dry. Could this be causing my problem?

Thanks again!
baddude Reviewed by baddude on . Where's my roots???? Hey all! After taking a nice 10 year hiatus from growing, I am realizing that I have forgotten way more that I realized (wonder how that happened?). Long story, short. I have planted seeds into rockwool cubes exactly 16 days ago. I have nice little sprouts, but there isn't any sign of roots starting to protrude from the rockwool. The cubes have been kept moist, but not wet with 1/3 strength solution and are in a dome to keep the humidity up. The spouts look great, but no roots. Rating: 5
