Top 10 Best Cheap Grow Lights For Cannabis: Your Easy Buying Guide

hydroponic grow lights, cannabis grow lights, led lights, hid lights, cfl fluorescent, cheap grow lights

Growing weed indoors is not always cheap. There is a lot of equipment to buy, from basics like seeds and nutrients to lighting, ventilation and more advanced equipment like temperature controllers, CO2 regulators, and more. Whether you grow in soil or in a full blown hydroponics system, the costs can start to add up.

While it is true that you can make your money back in a few months by growing the right number of plants, not everyone has the start up cash to start growing for a large harvest right away. Do not worry though, because there are always ways to save money on grow equipment, and you can start small.

In this article we will go over the best cheap grow lights for cannabis growers in 2018. There are a few different types of grow lights you can purchase, each with their own benefits and drawbacks.

HID or HPS lighting is inexpensive to set up, typically costing under $200 for a full kit including ballast, bulbs and reflective hood. The drawback here is that bulbs need to be replaced yearly, and you have to use separate bulbs for vegetative and flowering.

HPS also consumes a lot of electricity, which can increase your monthly bill. CFL or fluorescent lights are inexpensive and energy efficient, but unfortunately they only work well for vegetative growth. You can use them alongside HPS, or if you are cloning or germinating seedlings.

LED or Light Emitting Diode lighting is the most advanced technology in grow lights right now. They tend to be pretty expensive, with large LED grow lights sometimes costing over $500 each, but you can find smaller lights for cheap if you have only a few plants, say five or less.

LEDs are super energy efficient and will barely cost any money in electricity over the long run, and they can be combined as you expand your grow op, instead of having to just purchase all new larger lights. You also have the option of DIYing your own LED lights, which we will go over in more detail below.
