Going to try to journal my side by side grow since some of you on here were interested. I do ebb and flow so Im pretty hands off. I just check if everything is going smoothly and do my topoffs and water changes. I usually just let the crop do its thing in bloom. Anything significant like when buds start forming and ripening etc Ill document on here.
LEDs are Meijiu 650s vouched by bk78 and a few others on this forum are on my middle 4x8. Rest of this room is with 1KW Nanoluxx DE HPS.
Brand new DE bulbs fully loaded for this experiment.
Going to keep temps just a tad over 80F. I think that should do for the LEDs. Its a Co2 supplemented rm.
Going to be giving same nutrients. Its all the same strain. Skywalker OG. Ill adjust the nutrients to LEDs if i see any deficiencies.
The 4x8 tray with the LEDs was my strongest tray last run. It had 2 DE HPS fixtures and it pulled just under 6 lbs. My other trays didnt pull as well....they pulled 2per light... not sure why it was so low...but thats not important. Im going to be comparing this LED tray to the other trays this run and my previous run.
18 6x6x6 Grodan hugos per 4x8 tray. Ebb and flow. Fully sealed and Co2 supplemented rm. Plants were vegged and trained for 8 weeks.
2 MJ 650s per 4x8 tray and 2 DE Fixtures per 4x8.
The LEDs are ~22 inches away from the top of the canopy. Ill try to bring it ~15in depending on the stretch these next few days for maximum light.
Im going to try these lights for a few runs and see how it fares. My goal is to hit 2.5per light with them. Ive read about people hitting 3+ with fluences and gavitas online so its a reasonable goal considering that this Alibaba LED is pretty much the same specs. If I can hit that Ill fully transition to these strip LEDs and be done with DE fixtures for good. I usually hit anywhere from ~2.0-2.5 per light with DE so if I can accomplish the same with LEDs thats a win win for me.
Im a DE HPS grower from the start thats just tired of changing expensive bulbs every few runs and my high electricity bill. So Im rooting for the LED to beat the DE in yield.
Its not a scientific experiment but I have to get some info on this lights potential before coughing up thousands of dollars to fully transition this bloom rm to all LEDs. Hence this experiment.
Let the battle begin.
