Need advise from salty veterans on grow lights.

Right now I'm using 2 - 24 inch zoo med T-8 lights. One is a Coral Sun Actinic 420 Coral Bulb and the other is a Ocean Sun 10,000K High Intensity. I'm currently growning 5 plants, 4 seedling and 1 that's 3 weeks old, it's about 5 inches. Is this sufficient lighting or should I double my lights? Any opinions or advise?Thanks 1-Kandy Kush, 2 white widow, 1 white widow bomb, 1 dark devil 3wks old...

I am no expert, but while two 24" T-8's might be ok to Veg a few
plants under, they are not enough to flower much...not without
yield little, airy buds.

You will want to move to a HID or LED lamp for flowering.

Good luck,
