No Roots ?

My plants are 4 weeks old and i dont have any roots coming out of the bottem of the net cups. they are about 7" to 8" tall and seem to be growing fine. I am using 3" net cups. Should'nt there be more roots?

picture please....

at 4 weeks old, your plant should be much larger than 7 inches...

please tell us more about your grow...

medium?
lighting?

etc

I dont have a cam, wish i did . The plants were started in 1" rockwool then placed in 3" net cups with hydrotron. They are under a 250 mh. I use a drip feed 3 times a day for 10 min. Im using GH flora nova grow. When the plants reached the 5th or 6th node, they were topped, now they have 3 nodes on the two new shoots. All the lower branches have been pruned. I know i might be pruning a little to much. They should be in the flower side of the room, but its not done yet. Ijust thought I would see lots of hanging roots by now.

there is only 6 plants in an area about 3'x3'
