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.
The next step is a self-monitoring system to control it all. We assume you can’t spend 24 hours a day in your grow space! You need a 24-hour timer and an adjustable thermostat. The latter allows you to set your exhaust fan to switch on once temperatures go above a certain degree. The result is a relatively stable temperature range and humidity level while saving energy and money.

Lastly, consider using an RO filter as excess levels of chlorine and unfiltered minerals could harm the plants. You may want to choose a distilled option or at least filter it before adding it to your soil. Mineral-laden tap water can cause unwanted build-up in the cannabis root systems, which can lead to detrimental root disease.

We also recommend investing in a pH meter to check on the quality of your water and soil regularly. If you’re growing in soil, try to keep the pH between 6 and 7, with the sweet spot being 6.2-6.5. If you’re growing hydroponically, 5.5 to 6.5 is an appropriate range with the sweet spot of 5.8-6.0.
It can take anywhere from 4 to 8 months to grow a cannabis plant, this varies based on where you’re growing. If you have an indoor grow room, your plant has the ability to flower after only a few weeks!
