Howdy, folks! Thanks in advance for taking the time to review this. After a handful of exciting months researching LED tech, I’m nearly ready to pull the trigger on my first DIY LED grow light project. Please review the environmental details and project goals I have listed below. Environmental Details: Tent Size - 24” x 30” x 85” Grow Style - ScrOG (1-2 Plants) Grow Medium - Top Fed DWC or Coco/Perlite Hydro (undecided, sway me?) Project Goals: Completely saturate available canopy of 5 sq/ft Provide a quality spectrum for healthy, full cycle development Individual control over warmer and cooler light spectrums Run as cool and efficiently as possible Provide me with a deep sense of accomplishment After I recovered from the heart attack I received upon viewing Takeshy’s magnificent light, I fell in love with the idea of using Samsung LT-F564B 80 CRI 22” strips for my build. Samsung LT-F564B: 43.7Vf (min) 46.0Vf @ 1120mA 48.0Vf @ 1800mA (max) Core Part List: 3 x LT-F564B 80 CRI 3000K (SI-B8V521560WW) 2 x LT-F564B 80 CRI 5000K (SI-B8R521560WW) HLG-120H-C1050 powering the 3x3000K HLG-80H-C700 powering the 2x5000K Config: These will be evenly spaced down the long side of my tent 3K - 5K - 3K - 5K - 3K The sweet spot for the Mean Well HLG driver series, in regard to dimming efficiency, seems to be around 75%. The combined max output of the HLG-120 and HLG-80 drivers is ~245 watts. This should average out to ~49 watts per square foot in my tent. When dimmed to 75%, it will be closer to ~184 watts or ~37 watts per square foot. LED Questions: Am I under-powering my strips correctly, but still providing enough juice for my canopy? Should I be using even lower current drivers? Will my target of running the listed gear at 75% capacity still overpower my grow space? Should I mix 5000K and 3000K? Should it be 3000K and 3500K? All 3500K? General Grow: Can you tip the scales on Top Fed DWC versus Coco/Perlite Hydro given my described environment? Thank you once again for taking time to read through my madness. I really appreciate it! Cheers!
