I am gettting ready to change from 4 23watt cfls to 400 or 600 mh/hps combo by next week. My plants are around 17 days old right now and i was wondering if it would be too stressful for them. I am running light 24/7 right now. Any input would be greatly appreciated.
I would drop to 18/6 or atleast 20/4when you go to the new light. That is a great improvment in lighting. You will be happy you got the light. That light will burn hotter so be careful and watch temps....
Soil will likely dry a little quicker too. Keep an eye on 'em for stress, but they should acclimate within a few days.
Thanks for the replies. I cant believe they are 18 days old and still alive haha. I think i have done everything you are not suppose to at one point or another but i guess thats part of the learning . I will switch to 18/6 when i get the new lights and pay extra attention to the soil moisture. Thanks for the help
