My first grow using LEDs and the girls are nearing the finish line.
7.5 weeks in
White Widow on the right
Power Plant on the left
Jack Herer in the back
The cooler night time temps really brought out the colors in these three…
Happy growing

Lol just hear me out. Someone can probably explain this but has anyone ever felt the need to sneeze but it just wouldn’t happen until you looked at something bright? Well imagine an app that hit you with different light range frequencies and that in some crazy brain sciency way have you a hint of what it is you’re lookin at on the screen.
This is something I’ve thought about since the first iPhone came out and everyone lost their minds with the apps that were just lighters, matches, gun shots back in the mid 2000s, that was long before I started smoking the gigglebush but I’m just sayin…it’ll be a thing, one day we will be able to smell through our phones, and I am cannot fathom the joy I am going to have just full sendin a steamer through the air waves to my future grandchildren

HI Alexa,
The temp in my grow area is 60 degrees when lights are off. She started showing color when I switched to flowering schedule.
Never seen a plant go so purple before.
Cheers

Thanks for the reply I’ve heard of good things happening in cool night air, but don’t always hear the about the temps. So pretty, bet it taste as good as it looks! 
I don’t yet know how she tastes. She was cut down this morning and is hanging upside down to dry before curing. I speculate that she will taste amazing.
She was grown organically under a SF-4000. I was able to keep the light a few inches from the canopy which created very compact growth. Light on temps up to 82 and 60 at lights out.
Normally this strain likes it warmer and has more of an earthy smell. The environment I grew her in must have brought out a different side of the genetics.
She has a very powerful sweet fruity smell that is quite unique. I’m pleasantly surprised.
Happy growing.

Gosh those are beautiful! You said you have the sf 4000. I just got one and am about to start my first led grow. And tips? What heights and brightness settings did you use for the seedling, veg and flower stages? How close is only a few inches away?? Thanks in advance!

From seedling through veg the light was about three inches above the tops and about 80% power. What this does is creates really compact growth (P.I.T.A to trim) with short plants and very little node spacing.
I grow old school organic and my methods are slow and steady. In my experience (35 years since my first grow) plants grown under an SF-4000 will grow faster and reach harvest quicker than if they were grown under an HPS.
The advice I’d give about how to use the light will depend on how you intend to grow and the genetics that you will grow
Regardless, put a fan above your light and direct it at the center. These things generate some heat. The fan will help stabilize the heat and keep your grow from getting too hot. It also has the added benefit of extending the life of your light.
SOG or SCROG are your best options using an SF-4000. I say this because LED does not have the same ability to penetrate the canopy as HID and these methods can provide the best bang for the buck by getting maximum rays to where they need to be.
Don’t use too much N unless you want to trim a ton of leaves. Thin out the centers of your plants to let light in and have really good air circulation. Try to keep the light on vs light off temp swing to less than 10 degrees and don’t let your grow get below 65 degrees. The colder temps will slow down the maturation of your plants.
Personally, after a few runs with this light I’m growing a Wedding Cake strain that tops out over 34% and my SF-4000 is mounted as high as I can get it in the tent. I let the plants grow to it. They get about five feet tall and can yield up to 5 OZ each of incredible medicine that has eliminated my debilitating back spasms. This strain has very few leaves which makes it an ideal candidate for this type of grow. At 90% it provides more than enough light.
In a nutshell; it doesn’t matter how close or how far you put this light from your plants. It’s a great light and will do its job, you just have to do yours and give your plants what they need without over-loving them.
Happy growing
