    i've got 2 42w spiral flos right now on about 4 plants so they're growing incredibly slow which is driving me nuts...how many nodes or how big should they be before i can turn a 250hps? i really dont want them to keep stretching like they are

    Turn it on now. I use HPS from start to finish, I dont even screw around with floros anymore, too much of a hassle IMO.

    You can use it as soon as you'd like..but i prefer to use my fluros for the first week or so. Although the fluro i use is pretty strong (125w)

    i made the same mistake as you once. I put my sprouts under a cfl because i thought my 250w hps would be too much. They streched so far it took a lot of work to fix them.

    For years I have put seedlings that just popped out of the soil, right under my 400 watt HPS. Works just fine. Its never too early to give them decent light.

    Try starting the seedlings at about 12" inches from the tops to the light. Keep a fan blowing on it so that they stay cool and keep a close eye on them. Place the light at 12 inches above and then put your hand at the tops of the plants and see if your hand gets hot after a few minutes. If it does not then you are fine.
