Par question

They say 300 to 500 par is good and 700 + par is great

For instance a 300w Mars led Par value below at 18 inches

If you lower the light by 6 inches to 12 inches above the plants the foot print gets tighter but the Par value will increase by 50% , making light distance crucial.

I use from 10 to 15 inches depending on how I feel about it at the time
