how long?

After germinating seeds/ then put them in to rockwool cubes.

How long after do i turn my t5 light on when put into rockwool.

Then win it is time i would put the plant that is in the rockwool in to soil. wait for plant to get bigger under t5 then put under mh, then hps for floweing.

is this the correct procedure after germinating. or do i put the germinated seed into soil.

also how long will the t5 light (2ft) support the 3 plants before veg.

Thank you for reading, i could not have done this with out this site!

well.
Yea rockwool first is gonna work. Start the light after they sprout through that, usually 3 days after you put the seed that has germed into the rockwool. Once the roots come out the bottom, then stick it into some soil. Some folks wait until the roots are 2 inches long or whatever, but it works fine either way, but the roots arent gonna grow out of it unless you have it covered, as roots die when they hit light. I would go with a week or 2 after the pop through the rockwool, under the t5 before you stick the mh over it.
