Dear DGC. How much par value for cannabis germination to keep enough light on them to keep from stretching and then fall over? I am using a full spectrum light dimmed down to 50 Watts. I’m thinking about maybe 2 par or 200 par? You’re professional opinion I would truly appreciate your time and help. I’m germinating in Rock wool in a closed dome seed tray. Then once big enough then they go to the deep water hydroponic system. Thanks for your help and be safe.

par shmar. A 50w LED can be placed 6″-10″ away.
Use white light and stick to temps in the upper 70’s to prevent seedling elongation. A little warmer won’t hurt, but a more mild temperature will help.
Thanks brother 👍
I’m using a 100watt spider farmer that is full spectrum and I have it turned down all the way .
I was thinking maybe as they grow turn up the dimmer a bit?
Also thank you for the information about Temp I never new temperature had anything to do with how the seedlings stretch.thank brother 👍
