The advantages of LED Grow Lights;
LED Grow Lights greatly reduce power consumption.
This is great news for Mother Earth.Many brands now use 50-80% less than the equivalent HID.
They also deliver targeted high intensity light and are ideal for confined spaces.
Using LED Grow Lights also reduces the amount of heat generated.
The small size and low weight means they are great for using in racking which allows multi-tier gardening.
Many people using HID lights, have in the past been restricted by lack of ventilation. Not no more!
The price has come down so much in recent months that they may be the cheaper option for some grow set-ups.
They are quiet when running. Unlike some HID ballasts.
They allow 24 hour Light on periods for some types of plants, good for rapid growth.
They are a great addition to any HID set-up if you want to increase plant growth without extra heat and massive energy bills.
A lot of HID grow rooms will probably be using a mix of the two over the next few years as they replace old lamps for new.
LED Grow Lights may also be hung vertically within the foliage of a dense plant for additional energy.
