I have been searching and reading for many months to find the optimum light levels of PAR and to find the happy medium for the DLI.
I have read university studies till I'm bleary eyed. Problem is university studies deal with veggies and supposedly the closest reference to cannabis is data for tomatoes.
I'm a newer grower in a small tent. In a non 420 friendly state. I have a Timber 300 watt kit I'm using.
I invested in a Apogee meter and have used online info to calculate DLI levels for 18/6 and 12/12 photo periods.
The best info I can find is that for veg the DLI should be around 20-22 and for flower 23-26.
My last grow before I had what little info I can find I'm pretty sure I cooked my plant. The light will run 950-1000 on the Apogee readings and I ran it full tilt even though it was about 2' above the plant.
I know different strains have different needs. Last one was Blue Dream Humbold seeds. This one is White Widow. I have the light at the top of the 7' tent now and am using a DLI of 22 in week 6 of veg. Already have some nice pre lowers on one and they look good.
I just can't find any cannabis specific light levels to shoot for that top growers use or the pros who sell to dispensaries.
Does this info exist in the cannabis world or am I barking up the wrong tree?
