Prices have come down so much that you can get quality LED fixtures for far less than you would pay for the equivalent HID system.
Why are there so many things to think about and why do I need so much equipment?
This pH meter is inexpensive and works great. The General Hydroponics set of pH-up and pH down solutions is ideal for adjusting the pH levels to maintain balance.
Nutrients and pH Balance Recommendations
You should be fine using tap water for your weed plants. But you do want to know what is in it.
I don’t have any specific recommendations for any other climate control equipment you may need, since you can buy oscillating fans, air conditioners, heaters, humidifiers and dehumidifiers anywhere and they all work fine for the task. If you want some recommendations, check out our article reviewing the best fans for grow tents.
Required for Growing Cannabis
For timers, there is no need to go fancy. This single-outlet mechanical timer works great if you’ve only got one light. If you have more, you’ll find plenty of timers with multiple outlets as well.
If you’re buying a carbon filter separately, this one from Apollo Horticulture is great and sells for a reasonable price.
Your cannabis wants a safe, healthy place for root development. Without healthy roots, your cannabis will never thrive. Roots are in charge of water retention, nutrient absorption, anchoring the plant, and they also facilitate vegetative growth.
Humidity is the amount of water vapor in the air. Here are some ways to control it in your marijuana grow room:
If using nutrients, estimate how much water you’ll need for all of your weed plants so you can measure out and mix in the appropriate amount of nutrients.
What to look for in a pot

Inexpensive options include standard plastic pots or cloth bags, while some growers choose to spend more on “smart pots” or “air pots”—containers designed to enhance airflow to the plant’s root zone.
Soil and other media for growing weed indoors
Here are some ways to mitigate odor when growing weed indoors.
Inevitably, there will be fluctuations of temperature and humidity in your cannabis garden. These fluctuations can occur both throughout a grow space as well as within pockets inside a given room. They can also occur at different points within a given day or throughout a season as conditions change in the environment outside your grow space.
HID (high-intensity discharge) lights are the industry standard, widely used for their combination of output, efficiency, and value. They cost a bit more than incandescent or fluorescent fixtures, but produce far more light per unit of electricity used. Conversely, they are not as efficient as LED lighting, but they cost much less.
It’s also a good idea to have oscillating fans to provide a constant breeze in your grow room as it will strengthen your plants’ stems, making them stronger and healthier.
Setting up fans
What type of container you use will depend on the grow medium, the system, and the size of your plants.
