Ceramic Metal Halide (CMH) & Light Emitting Ceramic (LEC) Grow Lights

HID grow lights are much more efficient than fluorescent lights and are powered by large, oddly-shaped bulbs. They are usually screwed into a reflector or hood to reflect more light down onto the plants. HIDs are great at growing cannabis, but they also get very hot and are usually hooked up to an exhaust to help vent out heat.

T5s are much bigger/wider than CFLs and usually come as part of a panel, but they can still be kept mere inches away from your plants without worrying about burning them.

These are actually just two names for the same thing. This type of metal halide bulb uses ceramic as part of the lamp just like an HPS. As a result, CMH bulbs are more efficient than regular MH lights (though still not as efficient as HPS bulbs).

Cannabis plants under a T5 grow light – when plants are trained (like these ones in a Scrog setup) you can get pretty decent yields from fluorescents.

This bulb growth has a blue / white spectrum, this color is not in mercury lamps, so that Halide are more suitable for the growth of pot plants.

Ideally you want a lamp for each phase of cultivation, but today there are HPS bulbs (Agro, Dual or Grolux) that offer a combination of appropriate spectra for the two phases of the crop.

In Piensa En Verde you can find a bulb of high performance that is able to provide 10% more light than lamps conventional HPS, is the bulb Sunmaster HPS bloom Luxe 600w with which you get a high yield of your crops.

HM Bulbs

The HPS (the high pressure sodium) bulbs are best for the flowering phase of cannabis. How to distinguish the HPS bulb? The differentiate by its color, the light emitted is orange, although the technology is advancing rapidly and have already found new hues also go through the target. This bulb offers different types of power, there are 150, 250, 400 and 1,000 watts. Prices do not vary much if the power is greater or less, what we do is the result varies considerably depending on which watts are used. A recommendation should be said that less than 250 watts power is not suitable and neither is superior to the 1.000 watts power. These bulbs need about five minutes to go on making the switch to be the most costly expense. The sodium vapor lamps are more efficient because, among other things, reach the entire surface of the plant.

It is important to consider how much light will consume our plantation of cannabis, as a general rule in the growth phase of the marijuana plant are consumed daily around 18 hours of light (6 hours of darkness) and for the flowering phase, they need 12 hours of light (and 12 dark).
