This cannabis grow room setup list includes all the supplies you need to get to harvest.

You probably won’t need an exhaust fan for cooling in this setup, but if you don’t have an exhaust fan you can’t use a carbon filter, which means you won’t have a great way to prevent smells from leaking outside your grow space.

Summary of what’s needed for this LED grow light setup

LEDs are the newest addition to the cannabis grow light lineup (though they’ve been around for years), and they look to be the direction that lighting is headed in general. Aside from the allure of their newer technology, they are great at growing cannabis and the units themselves can last a very long time. In fact, the one we recommend can last 100,000 hours; that’s over 14 years if you harvested every 15 weeks!

Pros: Newer technology that’s actually still being improved, long-lasting panels (no replacing expensive bulbs), not stuck with one spectrum, really freakin’ cool

Light settings for growing weed

If you’re growing indoors for the first time, we recommend using a grow tent so you have a set space to work in with an already-reflective surface. The first choice you’re going to have to make is the type of lighting that you want to use.

Types of grow light setup – HID, CFL, LED

When it comes to efficiency, 400W bulbs produce good results in small grow tents (1 x 1 m), allowing for yields of about 200 – 300g, which is more than enough for some self-growers. 600W bulbs tend to be the most used ones for private growing as they tend to be slightly less expensive than the smaller 400W bulbs, and the fact that they provide coverage for larger tents, about 1.2 × 1.2 m. 1000W bulbs are usually used commercially due to fact that they’re a bit too potent for small grow tents. They’re usually used in grow rooms and can cover over 2 x 2 m.

CFL (Compact Fluorescent Light)

Each lighting system is going to require you to consider spacing and if you need a reflector or not; if you’re growing in a full room, you might want to consider covering the walls with reflective material or white paint at least in order to increase reflectivity when growing using HID lights (HPS and MH). For example, both HID and CFL lights require a reflector and reflective surfaces, as they produce light in all directions which means there’s a higher chance of actually losing some reflectivity, which means that your plants won’t receive as much light as they should be. If growing in a grow tent designed for this purpose, you shouldn’t need to cover the walls with anything as they generally come with a reflective surface.
