lighting question

hi, my plant started flowering earlyier then i expected so im runnin the hps the problem is i had 2 seedlings oin too i dont want to kill them, so can i grow them with an hps for 12 hrs then switch to mh for 6 hrs when i put my girl to sleep? or should i just run the hps for 18 on the seedling?

You can grow seedlings under and HPS if you are careful. I wouldnt switch bulbs daily as it appears you are implying. Sounds like you need a second room.

HPS is fine for vegging stage.. don't stress.... but there is a concern that HPS could damage or burn small seedlings..

cheers
