I am liking the LEDs so far. The seedling that is branching was planted just before thanksgiving and germinated a few days later. Maybe Nov 28 was when it sprouted. Many others that are a few days older are just starting to show signs of branching now. The big one is supposedly "Purple Butterfly". The others are Orange Ribbon.
Edit: I wanted to go into a little more detail about the LED lights I have been using. Keep in mind I have only been using these a little over 2 months.
My favorite is my 45 Watt which I purchased for just under $40 from Amazon. They are about 12"x12"x1" and contain 225 led bulbs, 60 blue and 165 red. The operate at wavelengths that simulate the two spectrum needed by plans to grow. Red support flowering and vegetative growth, and the blue supports stem and leaf growth. The size of these allow me to place many seedlings under one light fixture.
I also have a few E27 style bulbs that fit the general light socket. These type are what I started with and seemed to work well, just didn't have the coverage I wanted like the 45w fixtures do. I have some 120° that will cover decent area but at a lower intensity. I also have some 90° bulbs that work great for single plants, but dont have coverage for more then that.
The LED's use much less power then standard grow lights which is nice for my wallet and generate almost zero heat which means the plants can get closer to the lights without risk of burning the leaves. I also will say the LED's are working as an alternate light source for my seedlings this winter as the continue to grow well with these being their main light source. HID and HPS lights will perform better then LED, but are much more expensive and generate more heat, some of which require a setup to keep the bulbs cooler.
Hopefully this helps for anyone interested in using LED grow lights.
And thanks for the warm welcome.
