I tell people this until I am blue in the face! LEDs do not burn cannabis plants - PERIOD. unless they physically touch the diodes and then it is heat and not light that burns them.

The sun provides up to 2000 PPFD at noon and cannabis plants don't burn unless the air temperature is above ~95°F then maybe some strains could have trouble.

What people attribute to light burn is really a nutrient problem. LEDs are very efficient at converting power into light energy. With increased light energy the plant will uptake water and nutrients at a faster rate when the lights are turned up. It is the increased nutrient uptake that burns the plants. Many growers have too much fertilizer in the pot to start with and this just pumps it up into the plant.

I do not recomend and the science backs me up on this Do not run 24/0 at minimum give your plants 4 hours of dark per day.
What you said is very true, although I suspect not near as impactful on the uptake of nutrients when grown in an EarthBox with a method to foster two root systems.........one mainly for nutes and the other mainly for water.
I'm with ya on a rest period. I think the plant needs that period for rest and to make hormones..............more efficient and less stressful.

I wish I had two identical setups to run some limited pheno girls in two set ups running 24/0 and 20/4 to see if there's a trend over a few grows.
It's cool to read studies, but I think it's more fun if you're able to back up a study or even some bro-science.................or disprove!
 
ok, i coulda gone without that particular mental image :nono: .........................................but, i digress :rolleyes2: ppp
Lol apologies, as sweet on old lady as she is, its one of those ITS ALL I CAN SEE sorts of things :rofl: she'll be back Friday, so I'll try to remember to get a pic for yall (of the dog, not the 'roid).
