Switching from led to hps for flower?
Howdy, does anyone switch from a blurple led board for veg, to a hps or similar style light for flower? Why, why not? Is it worth the little extra hassle to buy and install? I like my led just fine, but wondering if there’s more to be gained in flavor, quality & yield. Thanks!

Should I put the light on before sprouting or not?
I'm most likely going to be transferring my autos from paper towel into my medium, I've heard some people say have the light on before they sprout and some who say after it's sprout, which is the best thing to do?

Light height
Hello all I have a mars hydro tsw 2000. I was noticing the recommended height is 24 inches for seedlings. Is this at 100% intensity? That's well over 1000 ppfd by my meter. I thought seedlings could only handle 200-400?

Turning lights off before harvesting
I've seen some growers who turn the lights off a couple of days before harvest, and I don't know why. Are there any benefits to doing this? or concerns?

Is the light far enough away?
Id like to make sure I'm not wrong in positioning the TS600 60cm above the rockwool cubes for germination.

How to measure lumens of a full spectrum LED light.
Since a lux meter only measures certain spectrums of light, how do I use a lux meter to determine the right height of my full spectrum grow light? I have it at the recommended distance but I have signs of light stress. Bleaching of some upper leaves. I moved it up 4 more inches?
