I have galaxy hydro 300 watt LED. First real grow in a while. It seems to be working pretty well but I have no baseline with another light to compare.I started a tomato plant from seed two weeks after I started a couple others outside. The ones that were outside the whole time were a much lighter green and not as robust. They are all outside now and have been for some time Now that LED tomato plant is the best one of the four. So, I guess LED's are okay. The really dark green is concerning though.
Anyway, just thought I'd share
Oh yeah my M plant is looking pretty good. 2 weeks flower

Dark green is caused from genetics or too high nitrogen levels, reduce fertilizer schedule to fade that out.View attachment 3503490 I have galaxy hydro 300 watt LED. First real grow in a while. It seems to be working pretty well but I have no baseline with another light to compare.

I ordered 9 3000k W90's a few days ago!! 
worked out to be $155.88/each shipped..

I have not yet started growing yet but am moving to CO in February. My cousin is currently in Cali doing his first outdoor season and has several years of indoor experience but is stuck on HPS. We are both going to rent a place in CO and I have been doing some research into LED and am thinking it is the way to go. I just found out about area 51 today and am impressed with what i have read so far. I am looking at these w90s and do not quite understand the difference between the 3000k 4000k and 5000k models and was wondering if someone could explain this a little to me..any info would be greatly appreciated

3000K is the spectrum of the light. 3000K is for bloom, 4000K is for bloom/veg and 5000K is for veg. Most go with 4000K for an "all around" or "do all" light.

what does temperature have to do with the light spectrum that doesn't make sense
Read the section on Colour temperature.

Kelvin is a unit of measurement used to describe the hue of a specific light source. This is not necessarily related to the heat output of the light source but rather the color of the light output. The higher the Kelvin value of the light source, the closer the light's color output will be to actual sunlight. Lights with an output of 3500K or lower on the scale will have an amber hue. Lights in the mid-range of 3500K-4100K will have a white hue. Lights in the higher 4200K+ range will tend to have more of a blue hue closer to, or exceeding, that of sunlight.

Must be the fox farms ocean forest cause I didn't add anything nutrients for vegetative phase. I did by some bloom nutes for flower stage. General Hydroponics. The strain is auto bubble.
What approach to the soil should I take next time to avoid too much nitrogen?

It is based on the color of something that is glowing hot. For example the filament inside a standard incandescant bulb is about 2700 degree Kelvin and a candle flame is <2000K.
LEDs dont get that hot they are under 360 Kelvin, but they emit light that simulates something very hot.

Kelvin is based on the color of a steel billit heated to said degrees. I think

Ok boys, some of you have had your W90's for a minute now - whats going on?
I have 6 of the 4000k's covering approximately a 3x3 area. Plants were vegged under T5 lighting until about 15" in height when they they were moved under the W90's. This has been for about two weeks. Plants are growing very well, with one COB dedicated under each plant. One they get to their final size the coverage will be closer to a 4x4, perhaps larger. I feel that 6 covering that larger space will not be adequate and will probably add 3 more lights.
As for the quality of the lights, I could not be happier. While there were/are big delays for these lights, Jeff has been incredibly helpful with any questions I have had.

What sized containers did you use? From my experience in a 4x4 I use 4 plants in 5 gallon containers vegged for about 1 month and I get a huge yield under a 600w hps like a pound each time. I scrog my plants using a 4x4 scrog I made. Sometimes less plants is better because they are easier to focus your attention on and easier to get to the bottom for watering.
Tha'ts really close to my old setup when I was using a 600w hps in a 4x4 tent. 4 plants, vegged for 4-6 weeks, 3 gallon pots, and yielded very close to a pound. Now, I no longer use a tent, and am in hydro. I use 6" Hugo blocks, drip irrigated. I now have 6 plants in same 4x4 space, but plants are smaller in size. This will yield over a pound using 6-8 W90's. My previous run, I used a 2x3 hydro tray under two, RW-150's from Area 51. 4 plants were in that and yielded 13 oz's. LED/COB is for real man. That easily matched a 600w HPS using only half the wattage (310w).
