    use the 26 watt daylight 6500k for vegging. I do 8 on Y splitters for 8 seedings. they are 1600 lumens each. don't forget to get a small fan cause it does get warm. good growing, aloha

    Keep light on 24/7 the first week or two and keep them very close. like an inch or two above the plants. Then switch to a 20/4 light cycle.

    A t-12 set up is cheap and works.

    I have this set up I use from time to time.

    They can grow into it for a few hours to a day they stay cool.

    My set up is (4) 24" T-12's 20 watts each at 6500k it's a light blanket.

    I also have some 2600ish k's (don't use but may add to my hps room for some side lights).
    These thing may be old school but you can not f--- it up.



    these are 26 watt cfl's




    under the 400 watt mh



    it grows under all the above just faster with more lights.
