Honestly I'd recommend more kingbrite kits over the HLG Rspec. I prioritize cost efficiency but if money is no issue by all means spend more. But $752Cdn for 4 240W kits shipped to Canada for myself is hard to beat through kingbrite. An Rspec is $1200+Tax here. Double the wattage, similar...
You happen to have feed schedule or specific ratios you use? MC in soil has always been remarkable but I'm curious how hard you push them with feeding in coco.
You would be able to run them in parallel on an hlg 600h 48a. Think i'm about to pull the trigger on some qb 800s and be a guinea pig for these ali boards, hell that many diodes for that price is nice and no heat sink is a blessing. Heatsinks cost more than Led strips here in canada
Hate to be a bother but I can't to see any mention of what your veg times usually are in your perpetual harvest now. Pulling nearly 1gpw with strips in ____ weeks of veg has me curious!
