Light bulbs used for growing weed

When cultivating cannabis is of vital importance light we use. Several types of light and each of them we can provide different benefits. But we must distinguish. The most used are the HPS and HM. We will provide here a little light to see what lies behind these two acronyms. HPS lamps are the sodium vapor, the HM metal halide.

HPS bulbs

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.

How do you maintain such a powerful light? Small inbuilt fans keep the lights cool and therefore eliminate the need for additional ventilation. Your plants will not suffer from light burn even though they are receiving plenty of light.

The only possible downside of these lights for growing weed is their sound. Some people may find the fans a little noisy (when compared to less powerful lights).

One of our favorite features – the main reason we’ve included it in our top 10 lights for growing weed indoors is their safety mechanism. Fires from faulty lighting are a dangerous risk, and this light comes prepared. The bulb has open and short-circuit protection. This protects you from being shocked when it reaches the end of its life, or if you try to switch it on after a defect with its ignition.

If you are looking for a great value, this light should be on your list. It is full-spectrum, and also optimized for marijuana growing because it includes dimmers that help the plants “think” the days are getting shorter. However, if you are growing autoflowers, this isn’t something you’d need to be concerned about.

7. The Vivavolt T5 Fluorescent Grow Light

For all types of cannabis, it is usually a good idea to purchase lighting that has both blue and red light spectrums. With regular plants, it saves you from the hassles and costs associated with changing the lighting to induce flowering. LED lights have a full spectrum of light, so you can use the same lights from seedling to harvest.

The fluorescent light tubes are also two feet long, so the four 24W tubes each provide double the amount of light that you can get from ordinary lights. The T5 is suspended from two points, making it easy to install or adjust relative to the size of your plants. This light system works very well for larger gardens because of how much space a single light can cover.

This fluorescent light is very similar to the fluorescent lights you find in people’s homes. However, the Vivavolt T5 also provides the wide spectrum that photoperiod marijuana needs to grow indoors.

Kelvins

The good news, however, is that this light has plenty of options. If you purchase and install a dimmable ballast, you can dim the light as needed. That makes the Apollo MH Light suitable for photoperiod cannabis plants at various stages in their growth process.

Regular incandescent bulbs give off more yellow and orange light, starving leafy plants while they burn them.
