I have 2 seedlings just a few days old. I have them under CFLs for now. I have a 150w HPS for them. So how old should seedlings be before using the HPS light on them?
Thank you very much for the reply. So what would be a good height to start at?2 weeks should be plenty just dont put it to close to them to start off
You can put them under what ever HID light you want as soon as they sprout.I have 2 seedlings just a few days old. I have them under CFLs for now. I have a 150w HPS for them. So how old should seedlings be before using the HPS light on them?
ok thank you. I will be using a 150w hps for 2 plants. The light has a glass on it.You can put them under what ever HID light you want as soon as they sprout.
keep in mind the heat from your HID will cook your new Seedling. So the light has to far enough.
A Fan is always a good idea through out the whole grow.
Good Luck on Your Grow.
