I purchased a small cheap LED for my seed making 2x2 tent at the time is cost $49.99. It's a BloomSpec SL600. It draws 85 watts at the wall. I have grown out a few plants between seed runs and have pulled over 3 ounces both times. One plant was WIFI OG and the other was Critical Kush. I'll post pictures if you'd like.
yeah lets see it, i was gonna purchase a qb similar to yours, but i liked so much the veg that i sticked to led bulbs, i see many people dont like it, but im fully not convinced that a 100 w board would do better than 100 watts of my bulbs,
my line of thoughts;
the bulbs have 20 leds, they are 14w therefore driving each led at 0.7w
on other hand a qb has 260 leds and 100w therefore driving each chip at 0.4w
if i put 13 bulbs i have 260 leds and 182w
see where im going?
what im saying is that i dont care if i pay 82w more if i get double the intensity / penetration per chip
the full spectrum in those 100w qb is 5 red leds 3 ir leds and 2 uv leds.. smh
so if i want to build something with greater penetration i just have to arrange my bulbs with the chips sitting close in the same fashion as a qb or a bar light but i have more watts per chip, ok im loosing efficiency doing so, because leds are more efficient if you underpower them , but i think i would have more penetration having the same count and distribution of smd leds
by the way these bulbs use the same format smd led as any qb or grow bar light (2835)
