400 w led is enough for 4 plants?

Looks like similar with mine . just a little bir different appearance. need to translate it english . those in the descriptions




The new SOL LED Grow lights are an engineering marvel that utilizes the most advanced integrated LEDs to create bright, intense and powerful beams of light. Just like the sun, it emits light beams in a concentrated and lossless state.

The LEFT LED Lamp is designed for 60x60 cm areas with a PAR value equivalent to 150w HPS. With its patented and special 5th generation quantum spectrum balancing feature; It has amazing properties that allow you to achieve record yields , much tighter node spacing , super - dense flowers and fruits , in short , bringing the sun into the house !

INTEGRATED COB LED

Integrated 50 or 100w 7 band LED Chips are produced by placing 3w chips on the same plate. The plate is completely copper and covered with silver to create a dense LED Matrix. Thanks to the integrated LED technology (COB LED), higher lighting efficiency and maximization of the benefit from the light are provided compared to other models using lenses. This returns as faster growth during the development and flowering period. COB LEDs have the best color ratio and are sufficient for all periods. The LEDs used in the chips are Epiled.

Each chip consists of 32 x 3w (100w) or 64 x 3w (200w) leds.
Color distribution

LED distribution on 32x3w chips:
660nm RED x 12, 640nm RED x10, 610nm Orange x 2, 470nm Blue x 3, 440nm UV x 3, 730 IR x 1 525nm x 1

LED distribution on 64x3w chips:
660nm RED x 28 , 640nm RED x16, 460nm Blue x 4, 470nm Blue x 4, 440nm UV x 8, 730 IR x 2,525nm x 2

Hey, what PPF of the cob led grow light would be? If actual power only 100watt, it's some low for 4x4' tent. Suggest use 150w or 240w led grow light for your tent, thks

helps to be able to adjust them to exact heights. I keep them 12-14 inches away. I was pushing them closer to 10 inches this past week to really swell up for flower, but started

15 lights for 12-14 plants. Topped lots of times. 5 gal buckets DWC / Coir or 10 gal soil. Veg for a couple months, and get monsters with only 1,500 watts per room for lighting

So I assume that you don't have them in the same space? but you have 15 lights at $80, that ends up being pricey not to mention the individual electrical draws from each light. If the majority are in the same space, why not one stronger light with a bunch of automation features. Easier and simpler?

15 lights in the same room, three rows of 5 lights. I like having extra lights so I can adjust height and angle specific lights the exact way i want them for the specific plant that they’re covering. It also allows me to have even light distribution throughout the entire room. Approx 12x12FT for both flowering rooms. 15 lights each. The big lights are nice but hard to cover more than a 5x5 or 6x6 area with one; yet alone 12x12 or 12x14

I hear ya, every hobbyist has a different style and technique of growing. Now I get why you are using 1 light per plant. I guess with the legal market up here in Canada, I see alot of and consult on micro to large scale grows so efficiency are part of their goals. They couldn't have a set up like yours over 900 plants.
