just wanted to update,, my bloom room is a 4x6ft f&d table w 37 plants. my lighting above is 2 315 watt cdl's in line over the center and 2 go green 100 watt citizens, 1 is 3000k the other 4000k these are placed between the cdl's 1 and a half feet in from each side of the table.. my previous runs w/out the led the 1st and 6th rows each the outside rows had a bit smaller buds, after adding the led bud size is pretty uniform. running a total of 830 watts im getting 1300 grams after trimming and drying ive now finished 3 runs w this lighting set up and each run was within 15 grams give or take.. so overall averaging 1.56 grams per watt...
after using the cdl's i would never go back to HPS or MH, Bud quality is better, plants finish sooner under the spectrum, and my gram per watt is up from 1 to 1.56..
as for the led,, i keep them at the same height above canopy as the cdl's 2-3ft above. they seem to have pretty good penetration and wile the plants under them are getting bigger buds they are still a bit smaller than buds under the cdl's...
1-2-3 -4 -5 -6
7-8-9-10-11-13
14-15-16-17-18-19
20-21-22-23-24-25
26-27-28-29-30-31
32-33-34-35-36-37
the cdls would be directly above between plants 10 and 16, and22 and 28 the leds above and between plants 15 and 21, and 18 and 24.. plants number 1,6,32, and 37 are always the smallest...
i love the 315 watt cdl's and im still on the fence on the leds,, i have not done any runs under led alone but i have w the cdls.. i have also found plants directly under the led's tops will burn quick if they get to close and they seem to use nutrients differently than plant under the cdl,, plants under the cdl's seem overall healthier... with a flood table they all get the same thing,, i would say if using both led and hid you would be better off hand watering plants under the led with a milder nute mix...just my opinion..
