Even sunny glass greenhouses can benefit from supplemental grow lights, especially to boost the illumination of darker or dimmer corners. If you are growing in a grow tent you will need to make sure that your plant grow light is penetrating through the canopy and providing plenty of light to every square inch of grow space to get the biggest, highest quality crops. There's several of options for additional lighting, such as fluorescent T5s and CFLs.

More About Grow Lights

LED Grow Lights

LED’s are efficient and economic to run. The cool running of an LED system eliminates the risk of heat damage, and fire hazards. LED’s typically last for 50,000 hours+, whereas HID bulbs generally last 10,000-18,000 hours.

Dual spectrum LED systems can be used throughout your grow cycle with no switching of bulbs. You can even install a system that’s tailored specifically to the type of crop you grow. LED’s, fit into smaller, tighter areas, meaning you can create a more compact grow room, without the risk of heat burn. LED lights normally come with a built in ballast of sorts. So you would not need to use an additional ballast as you would with a HID style bulb.

HID Grow Lights

HID’s (High Intensity Discharge) lights are extremely powerful and as a result are expensive to purchase. The powerful nature of HID lights means that they do have a tendency to consume electricity inefficiently and give off a lot of heat. As a result HID lights require special light fixtures and ballasts.

Despite these points, HID lights are very effective and remain one of the most widely used lighting options within the hobbyist indoor gardening industry, as they produce great yields! HID’s are best for large plants because the intensity of light penetrates farther into the foliage than other bulbs.

Metal Halide (MH) grow lights

Metal Halide Grow Light Bulbs are best used during early Veg, as they produce light in the blue spectrum (cool light). MH lights can be used throughout the entire grow cycle but it’s recommended to use MH for Veg and then move to the HPS for Flower. If however you only have the option of buying one bulb, I would recommend that you choose the HPS bulb as it will perform better over all through an entire grow cycle.

Compact Fluorescent Bulbs (CFL’s)

CFL grow lights are reliable and economical for raising seeds, cuttings and for vegetative growth. CFL’s produce little heat, consume little power, and require no ballast, making them a good choice for small gardens or tight budgets. CFL’s can be used throughout your plant’s entire life by alternating between the blue and red spectrum. Be warned however that using CFL’s throughout Flowering will result in lower yields than if you use HID lights.

T’5s, Fluorescent tube lights

T5 Grow Lights are primarily used for propagation and Veg when blue light is needed most. T5s are not recommended for the flowering/ fruiting stage, as they will yield considerably less than a HPS grow lamp. T5’s are available in 2, 3, 4, and 5ft lengths. They are 40% smaller than T8 fixtures but are capable of producing just as much and sometimes more light in a smaller area. They are lower maintenance than other fluorescent bulbs and provide more light (lumen) than other fluorescent bulbs, saving you money.
