We strive to carry the widest selection at the lowest prices. Check out our guide on When and How to replace grow light bulbs in our learning center.

The Best Grow Light Bulb for Growing Plants?

There are several factors which you must take into account before you get yourself a grow light bulb. First and foremost, it’s the grow space. Both MH and HPS Grow lights work exceptionally well with a large amount of space but produce a great deal of heat. On the other hand, CMH and LEC bulbs are currently the most efficient HID grow lights available on the market. These bulbs are more efficient and generate less heat than MS & HPS Grow Lights. The best part is that these bulbs are also last twice as long as other HID bulbs. Last but not least, fluorescent bulbs are the best-suited option during the propagation stage, since they perform well, at lower temperatures and are less likely to burn your plants.

Best Light for Indoor Plants?

Every grower knows that plants require light from different parts of the spectrum during their different stages of growth. For instance, a blue spectrum during veg leads to leafy growth – eventually giving birth to more bud sites for the flowering state. The red spectrum ensures heavy budding during the flowering state.

Are Full Spectrum Light bulbs good for indoor growing?

YES. Providing a full spectrum of light, similar to the sun is critical for plants if you want to achieve monster harvests. Instead of using different MH & HPS bulbs to achieve this full spectrum, using a full spectrum grow light bulb is an efficient use of your resources. Full Spectrum Grow Light bulbs can provide enough lighting for all phases of your plant’s growth easily. We also carry a range of full spectrum led lights; in case you want to upgrade your grow lights.
