So are you saying you pull 4 Ps(3 bud/1 trim)a light with spydrs?And you have been growing only 2 years but yet you have run 8 different types of lights to full harvest and now you know spydrs are best?And for numbers, when I was keeping track my best run was Skywalker kush. I ran 16 plants in a 4x4 under one Spydrx and pulled 3 bags and had over a whole one in trim to run into oils.
i for one value your opinion here seeing as you actually have a grow and speak from experience.seeing alot of pretengineers giving bad info lately,or flat out just posting to see their own text lol.i have run 360w cmh,400,600,750,1000w hps and mh in many dif combos de lamps as well as currently run de and led.have used uv lamps with my setups for 1,2,3,4,6 hour times with de and led(cobs) and still my best thc tests came from under a quantum/cob panel no uv. par is par and meters dont lie.de hps do not give much par at 20 inches down and 20 inches to the side.my 30" x 42" led panel does,almost double.so when i see the word penetration used i lmao.can you make better par with a de,sure.you will need to run them at 18 inches and spaced on 4 foot centers.but good luck with those nugs right under the lamps ;)Agreed zen, opinions are like assholes and everyone's got one. You either speak from experience or you speak from what you think you know.
hey 6 @sixstring do you know if there was ever a follow up video on this test? Would be interested to see the final wet and dry yields and potency testing.some good par comparisons
dry weights here in this postpeople dont want to admit they fucked up setting up a large room with the wrong lights,so they will never switch to led. or then theres actual results lol
you dont take par readings at 12 inches with de lamps because you dont let plants get that close,they would cook pretty bad lol.par numbers under my nanolux after 6 months is pretty lame at 3 feet maybe 650 right under the lamp and barely 400 in the edge of a 4x4.those lamps are supposed to be good for a year lolhey 6 @sixstring do you know if there was ever a follow up video on this test? Would be interested to see the final wet and dry yields and potency testing.
My only thoughts after watching the video is what would the gavita and Papillion par readings have been had they been taken at 12" as well. Seems the inverse rule applies here with loss of par the higher the lights are. What I find impressive is being able to hang that much par that close to the canopy with the spyders and not have the same thermal management problems and using much less electricity as with using HID lighting.
Thanks for sharing this video.
I've grown with HPS, Purple LED's and am now running Samsung LM301B diodes.i just dont think LEDs are quite there yet. they are coming along though. how was the bud structure. was it airy? the running joke in the industry is "what do you use to supplement an HPS?... another HPS!" it will be interesting to see how the tech comes along. i dont think it can penetrate the canopy efficiently
