led wattage for growing weed

Even if you’d like to grow more than a few plants, you don’t have to go for the more expensive HID lights. Simply add to your setup with either a few larger LED bulbs or several of the smaller ones. If you opt to go for the latter option, make sure that your plants and your lights are spaced out correctly, as you want to make sure that each plant gets adequate amounts of light. Using too few lights can cause stretching, whereas using too many lights leaves you at the risk of light burn, as well as energy overconsumption.

For many, the main reason is that they are relatively inexpensive when compared to the much pricier HID setup. This is especially true if you are growing a smaller number of plants. Our grow lights at A Pot for Pot are specifically designed for growing a small number of marijuana plants and is priced well under $200 – proof that high-quality lighting doesn’t need to be expensive.

If there is one drawback of using LED grow lights, it is that your plants’ grow time will be slower than if you were using HID lights. Again, this is because HIDs emit more energy than LEDs, leading to faster flowering.

You should also be aware that while LEDs don’t put out as much energy, your plants are still susceptible to light burn. So, like any other lights, make sure that you are keeping your lights a proper distance from your plants and keep plants dry when under direct light.

It used to be that lighting was one of the most expensive aspects of growing marijuana. A good set of HID or CFS lights could set you back a couple hundred with all the required equipment. Now, thanks to LED lights , cannabis grow lights are much more affordable, making growing cannabis at home much more attainable.

The benefits of using LED cannabis grow lights are many. The next big question is how to grow marijuana using only LED lights. A good rule of thumb is one light per every 1.5 square feet. This generally will yield you up to 6 ounces per plant, which ends up covering what you spend on the light and will definitely end up saving you money in the long run. If you are growing only 1-2 plants, our single 75 watts LED light supplies plenty of light for your plants.

Why Use LED Lights?

If you are willing to step up the quantity of your grow, that is, really take it to the next level, you should be prepared to spend a little bit more cash. A large scale 350-400 watt LED operation that will outdo the average 600 watts HID lighting system is not going to come cheap. However, a larger LED light setup will still be more cost-effective than an HID setup of the same size.

With LED cannabis grow lights, this is not the case. Different color LED bulbs give a grower the ability to manipulate the color spectrum, thus allowing you to use the same light setup for both phases of growth. This not only eliminates the need to purchase two different types of lighting setups, but you’re also guaranteed the best results in your plants!

Several growers believe LEDs produce higher quality buds (more trichomes, higher potency, and bring out the natural taste and smell of buds). They also tend to bring out colors.

Which LED grow light brands can be trusted?

Yields! With a quality LED grow light and an average-to-good grow, you can expect yields of about 0.5 to 1g/watt.

These HID bulbs usually contain sodium, mercury, and xenon, and produce a yellow/orange light, and are commonly used for flowering plants. Some growers will start plants under MH bulbs and switch them to HPSs when plants go into the flowering stage, using the same hood. These lights also require a ballast.

The typical homegrower will only need one or two lights. Most states limit grow amounts to 6 or 12 plants, and one or two lights should be plenty for that. If you plan on running two separate rooms, one for vegetative plants and one for flowering plants, you’ll need two lights.

When growing outdoors you can harness the power of the sun, but in an indoor environment, sunlight is mimicked through the use of grow light bulbs, which aim to display the same spectrum of light as the sun.

MH (Metal halide)

You can find lights for under $100, but they may be low quality and not produce the right spectrum of light, and you can also easily spend as much as $2,000 for a large, state-of-the-art LED.

How big a light you need will depend on the number of plants you plan on growing, but also on the size of your space. If you’re growing in a closet or a small grow tent, you’ll only be able to fit one small light in there. If you have a wide open basement, you could invest in a bigger light as opposed to two smaller ones.

There are many different kinds of lights out there, so it can be daunting to know where to begin. Here’s a guide to four basic types of grow lights on the market and the pros and cons of each.

Other considerations when choosing a cannabis grow light

Here are a few different HID grow lights at different price points.

Both types of HIDs are usually inexpensive to buy but will eat up electricity. HIDs throw off a lot of light and heat, which the plants need to bulk up and get potent. But, they run hot, contain heavy metals, and ballasts can fail.
