What are the best LED Grow Lights?

There are several things you need to look for when you are buying one of these grow lamps

Firstly they need to have the full light spectrum. This ranges from 380nm to 800nm and covers all the different colours. This is important because plants need different light at the various stages of growth. For example red light in the 600 to 730 range promotes flowering for later stage plants

I think it's also very important that these lamps are programmable so that you can set them to different levels at various times of the day and at various stages of a plants growth

Power is the next thing on the list. If you want to cover a large area then you will need an adequate lamp. There are massive differences in the models we have shown above so make sure you get something thats powerful enough for your needs

I am someone who enjoys a little gardening. Now I am not someone who spend hours in the garden, but I do like both my front and back gardens to look really nice. Well kept lawns, neatly trimmed hedges, and borders filled with plants, make a huge difference, to how your property looks.
