When you’re growing Cannabis indoors, you’re at a sure disadvantage as compared to those who cultivate their weeds outdoors. They have the privilege to use natural light from the sun for the proper development of their plants. It’s a great thing, though, that you can use grow lights to mimic the lighting effects from the sun.
Among them are the HPS and LPS Grow Lights that have been around since the 1960s or longer.  While there are lots of more “modern” alternatives” today like LED, COB, CMH, or CFL lights, some people still believe with HPS Grow Lights for still being one of the best (and cheapest!) alternatives for growing cannabis. Today, we will shed light on the advantages and disadvantages of HPS Grow Lights and its counterpart, LPS Grow Lights, to know which one will work best for your plants.

HPS GROW LIGHTS

HPS lights take form in a narrow arc tube supported by a wire flame. These lights contain high-pressure solid sodium, xenon gas, and mercury. It works by utilizing a ballast that produces a pulse, stirring the gas in the lamp or bulb. To create a flow of electrons, the ballast initially ignites the xenon. Once the arc heats up due to the electrons, it will emit a pale blue light. Then, the arc will start to vapor the mercury to produce a deeper blue color. Lastly, the high-pressure sodium transforms the arc in a yellowish spectrum. All these create a lighting effect that promotes the healthy and robust growth of your greens.

Advantages of HPS Grow Lights

They Usually Come in Kits – Purchasing HPS grow lights can be easy because they come in sets. This means that you do not need to purchase anything else anymore because you can already get what you need.

Energy Efficient – No need to worry about how much you are going to spend because you know that they are energy efficient.

Can Prompt Flowering Plants to Flower – Since they can provide red lights, you can be sure that they will be able to let plants flower adequately.

Disadvantages of HPS Grow Lights

Expensive – If you do not want to spend too much money on kits, HPS lights may be a bit more costly than your current budget.

Hard to Dispose of – HPS lights use mercury, which can make it hard to just throw away in the trash can as it can pollute other items that are available.

LPS GROW LIGHTS

LPS grow lights, on the other hand, are known as low-pressure sodium plants. They are known to stop infrared rays, so you do not have to worry about using them. They are known to usually produce white or yellow lights.

Advantages of LPS Grow Lights

Maintenance of Intensity – You can be sure that the lamp will be able to maintain the intensity of the lights with ease.

No Heat – Are you wondering if the heat from the lights will hurt your plants? You can be sure that since it does not generate heat, you do not need to worry about anything.

No Pollution – Unlike other plants, they will not produce any pollution for you.

Disadvantages of LPS Grow Lights

Lower Intensity than HPS – If you would compare this to HPS lights, they may not have the same initial intensity. May Require A Lot of Space – You may have a hard time trying to put them inside your own home, probably because they may take up a lot of space.
