Sun light intensity

Hello.
Anyone know how much lux is required for successful outdoor grow?
What's the minimum lux required and after how much it doesn't make any difference?

I'm asking because of losses of lux trough green house foil.

Measured luxes today.
Direct sunlight and in the green house.
Note that its still February, so in summer sun should be even stronger. Or?

Direct: 132k lux
Greenhouse: 67k lux

Losses are around 50%..

Put the LUX meter away. Your plants will get plenty of sun outside in that greenhouse.

Back in my day. you needed a lot of lux not to have a helicopter find your shit. So I carried a luxy rabbit foot. Fucker ate my weed, I wore his paw.
