best led light bulbs for growing weed

As with HIDs, you can find CFLs at any local grow shop.

Lights have fixtures and bulbs, and some require a ballast. Depending on the type and model, the bulbs or the fixtures can be more expensive. There are a lot of abbreviations, but don’t be alarmed.

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.

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.

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.

Power equals poundage, so if you want big yields you’ll need more wattage. Professional LEDs can start at as little as 200 watts, and go up from there. A high-watt light can double the work of several low-watt bulbs.

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.

Safety

One of the crucial elements a cannabis plant needs is light. During photosynthesis, a plant converts light energy into chemical energy, allowing it to grow strong and healthy, and with cannabis in particular, light also fuels bud production.

These fluorescent lights are cheap and efficient and great for vegetative growth. They’re especially great for helping along germinating seeds and small seedlings because they don’t put off much heat and won’t scorch the delicate seeds. They won’t run up your electricity bill too much.

They are favored amongst growers that don’t want to hassle with complicated ventilation setups or don’t want to have loud cooling fans in their grow space. Furthermore, fluorescent grow lights are cheap and use less electricity than HID lights.

HID Lights

The main reason this grow light is on the list in the first place is its central chip-on-board (COB) LED from Cree, and the ideal color spectrum for weed farming. COB LEDs are more powerful than standard LEDs, which allows them to penetrate deeper into the canopy. They also emit full-spectrum light that weed plants love.

Like I mentioned in the introduction, the only thing I don’t like about this product is how loud the cooling fans are. You won’t be able to hold a normal conversation if you have it turned on. It also offers no water resistance, but that is a given for most budget grow lights.

It’s All In The Spectrum

The central COB in this affordable ufo grow light produces 3000k warm light that contains all wavelengths, while the surrounding Bridglux/Epileds produce additional red and blue light that is needed throughout your plant’s lifespan. Don’t worry, it also has UV and IR diodes, so you can use it for germination.

LEDs can get pretty pricey, though not all brands! In fact, some great brands are actually some of the cheapest!

Average Yields: 5-11+ ounces – keep in mind that the strain (genetics) and any plant training you do makes a huge difference in your final yields

AutoCOBs

How Far to Keep from Plants: 24-38″ is the standard starting distance for the vegetative stage. You can move it to 18-20″ away in the flowering stage, or possibly even a few inches closer for light-loving strains.

Grow Space: Up to 3’x5′ in the vegetative stage, 2’x4′ in the flowering stage

How Far to Keep from Plants: 36″ is the recommended starting distance from the plants.
