Seed Question

Hi guys - Got a seed question...???

I've germinated some seeds and put them into rockwool and are currently under a cool white fluro.....

They are doing well and have broken through the rockwool and will soon be plants

My question is - How long can I keep them under the fluro and when would I have to start giving them nutrients

Eventually they will end up under my HPS in vegie mode......!!!!

depends on the time you have they take much longer all the way thru with the tubes but they still work, see?

All I'm trying to achieve is to get the seedling ready to go under the HPS light in vegie mod.........I'm worried about them dying from living on straight water for a couple of weeks.......Untill they are big enough to go under the HPS....

one cfl is all you'd need then, maybe 2
