Seriously?I'm running 1200w of LED in a 4x4. It replaced my 6000w hps.
I don't really have a 6000w HPS but I am running 1170w of LED in a 4x4 space.. 9 x 130w 48" strips.Seriously?
1170 watts of actual draw from the wall in a 4x4? Seems quite excessive.I don't really have a 6000w HPS but I am running 1170w of LED in a 4x4 space.. 9 x 130w 48" strips.
I don't think it's excessive and neither do my plants unless I'm 8" off the canopy. The point is Im keeping the lights higher and getting more even distribution along with better light penetration. I'm matching my target DLI in every square inch. Where most sit at 1000 micromoles at center and 500 micromoles at the edges I'm at about 1500 micromoles evenly distributed throughout the entire canopy.1170 watts of actual draw from the wall in a 4x4?

Do you have the lights 8' off the canopy then? What brand is it?I don't think it's excessive and neither do my plants unless I'm 8" off the canopy.

You are frying your plants. Look at how they are starting to taco and the serrated edges are all standing up as much as they possibly can. Also the light green color.The light is 48" x 48" and is sitting about 16 - 24" above the canopy depending. I'm trying out a budget brand light that's performing as well as other lights costing twice the price.
White Rose LED strips 130w each
I bought the White Rose 9000w(6 strips) + White Rose 4500w(3 strips), same lights, and combined the 9 into one light.
cool story. but learn how to read your plants. leaf margins arent' supposed to do that.They look good to me. When the light was 8" away they were lightening from the light but since I moved it up they look healthy and are producing fast. The plant is definitely utilizing the additional light.
"While many indoor growers give their plants around 300 to 750 micromoles of light per square meter per second (µmol/m²s) using either double-ended, high-pressure sodium (HPS) or specialized horticulture LED lights, the researchers found that a simpler and more cost effective lighting setup can result in even greater harvests.
Cannabis crops continue to grow in a linear fashion as lighting is intensified at least up to 1,500 µmol/m²s. And that’s achievable by using high intensity, broad-spectrum (white) lights that cost a fraction of what growers spend on those designed specifically for horticulture.
It’s also more than twice the intensity of a 1,060 watt HPS light, which is “almost universally considered the optimal lighting for growing cannabis.”
For their experiment, the team, which involved personnel from the Greenseal Cannabis Company, grew hundreds of plants and kept all other conditions like temperature and soil composition constant. But the crops were exposed to different types of light and light intensity. They discovered that for every additional µmol/m²s that reached the plant, the yield increased by .41 grams.
So when a plant was exposed to an HPS light that delivered an intensity of about 500 µmol/m²s, the total harvest was just under 300 grams. But plants that got 1,500 µmol/m²s from a general purpose LED light produced up to nearly 800 grams."
I'd rather push them to 1500µmol then stay at 500..
Your plants are clearly stressed from the light, believe it or not.They look good to me. When the light was 8" away they were lightening from the light but since I moved it up they look healthy and are producing fast. The plant is definitely utilizing the additional light.

Maybe but they're also resinous as f and growing substantially larger day by day.Your plants are clearly stressed from the light, believe it or not.

Excuse me? It's relevant to the discussion.Did you really just copy and paste a article from weed maps?
they'd grow even more if they weren't stressed.Maybe but they're also resinous as f and growing substantially larger day by day.
Definitely. Please keep us updated on your grow.They look good to me. When the light was 8" away they were lightening from the light but since I moved it up they look healthy and are producing fast. The plant is definitely utilizing the additional light.
