Here's the Quick and Dirty
There are a lot of cheapie LED's on the market today and the vast majority of them are very poor at growing cannabis. You can definitely grow plants, just not stellar cannabis. So what are the best recommendations today for getting the most cannabis for your LED buck?
Best of the Inexpensive LEDs
You want LED and you want it now, but your budget is a bit limited at the moment? You'll be wanting to take a serious look at the Galaxyhydro Roleadro 1000w. The testing has been done by a few growers now. At $99 for 200w of decent quality LEDs, it's killing it on a budget. Here's the link to the data dump on lights where you can see the comparisons of a number of different LED lights by cannabis growers and by spectrum output.
Budget Not an Issue? These are Today's Best of the Best in LED Lighting for Cannabis
When you want the absolute maximum quality and efficiency from your LED lighting, there are 3 companies standing well ahead of the crowd. Using the latest ceramic based LEDs on the market and high quality craftsmanship, these lights will last you a minimum of 10 years of top of the line performance.
As you can see from the writeup I shared, Black Dog LED, Fluence and California Light Works are the top of the line off-the-shelf lights for cannabis in the USA. These guys are working directly with cannabis and their lights, so you know their results are better than 'general' LED lighting for common plants.
LED's Are Crushing It Now!
The latest advances in ceramic based LED chips have as little as a 10% decrease in output over a 10 year period. The older plastic based chips have a 30% decrease in the same time span. Awesome!!
