Congrats on the light! how high do you have it above canopy?
Thanks for the comment. Your question stirred my interest on what PAR the girls are getting.
The HLG is about 12"-14"=30cm above and basically maxed to the top of the tent. Its dialed down a bunch and giving a PAR of about 1000 to the tops of the colas and about 700 to the lower/ middle buds. There is about 6"-8" above the light but I need that space to keep the electronics cool.
I have my old light about the same distance above the Jack Herer but it dosent have a dimmer switch. Come to find out shes getting a PAR of around 1500.... oops. I turned off the veg switch so she is getting straight red light over head and some side light from the HLG to give her a PAR of about 1100 at the top of the cola. Maybe this will help.
