How much sun is good

[Wowsers]

Can too much sun be bad or stunt growth

Only if you have it too close to the sun.

As much as you can get them!

Mojave desert or Death Valley may be too much sun there.

Yeah as long as temps are cool enough you can use the 1k watt per square meter of sunlight. That’s around 100 watts per square foot of free light

Thanks. I needed to know that as well. I'm about to put four outside for my first outside grow. That's a good question...!!!👏

I live in the Sonora desert. My plants get full sun all day and all season long and they love it. I sprout my seeds in full desert sun this time of year.

You may want to give them partial shade at first until they harden off if they've been under mild lighting indoors.
