High output CFL Grow Lights are extremely cost effective, easy to set-up and efficient to operate. These bulbs fit into most standard screw-in light fixtures. Full spectrum lights (6400K) mimic the sun of mid-afternoon in June: perfect for growing a wide variety of edible and ornamental plants.

We recommend CFL grow lights for maintaining productive growth on plants wintered indoors.

These bulbs are also a popular option for general lighting around the home as the light is similar to what is used in SAD lamps and sets a more cheery tone indoors compared to the orangey colour of common bulbs. 

We recommend 16 hours on / 8 hours off for best growth.

The lights should be between 4" and 12" above the tops of plants (further away and there is little benefit / closer and there is risk of tender foliage getting heat-scalded).
