One trick to avoid hot temps is to have the grow lights on during the evening, when it’s cooler outside, and leave the lights off during the day when it’s hot. This may help bring down the temps, but you’ll only be able to work on the plants at nighttime when the lights are on.

How to set up an indoor grow room

If you can’t afford both MH and HPS bulbs, start with HPS as they deliver more light per watt. Magnetic ballasts are cheaper than digital ballasts, but run hotter, are less efficient, and harder on your bulbs. Digital ballasts are generally a better option, but are more expensive. Beware of cheap digital ballasts, as they are often not well shielded and can create electromagnetic interference that will affect radio and WiFi signals.

You can also use a timer for your fans, but a thermostat is better—you can set it to a specific temperature, and the fans will turn on when it’s too hot and turn off when it’s too cold.

For example, most growers use one of two main types of HID lamps/bulbs depending on the developmental stage. Metal halide (MH) bulbs are best during vegetative growth. High-Pressure Sodium (HPS) is the preferred option for the mature flowering stage. If you can only afford one, choose HPS as they are much better for flowering and are more efficient on a ‘watt-to-light’ scale.

The most commonly used lights for DIY-style growing are probably HID (high-intensity discharge) grow lights. They typically represent the best overall value in terms of cost, efficiency, and ease-of-operation.

Induction grow lights

By “small,” I mean nothing more than a few plants at most. You can start with just one or two plants. There’s an inevitable learning curve involved with growing weed indoors and you’re bound to make some mistakes.

Here’s a basic rundown of the most popular types of cannabis grow lights used today.

LED grow lights

HID lights produce a substantial amount of heat. Therefore, proper use of air circulation and conditioning becomes vital. Some growers choose air-cooled fixtures to mechanically remove heat.
