Par question

[Hillbilly420]

How many pars does it take to grow one plant. Lets say for instance that I put my light 1m above the canopy and the par meter tells me 83 par. And the lower to the floor lets par and closer to the light the more par I get. So how many pars would it take to flower one plant?

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
