Whether you call it weed, cannabis, pot, marijuana, or something else, the plant known as Cannabis sativa is actually easy to grow at home when you know what you need to do. Growing hydroponically will provide you with higher yields and a shorter grow time compared to growing in soil, but it can often be difficult for the beginning grower to get started with hydroponics. However, most people think of plants growing in water when they think “hydroponics” but actually your plants will get many of the benefits of hydroponics as long as they’re getting their nutrients directly in their water supply. However because of superior air to water ratio in hydroponics, it remains the industry standard. This tutorial will show you step-by-step how to grow your marijuana in 3-4 months using the (arguably) easiest hydroponic method: hand-watering in a soil-less medium.

Growing cannabis at home can be a fun project and a nice way to have your own cannabis plants on hand. You may want to grow cannabis indoors due to inclement weather in your area or due to a lack of green space in your yard. Start by germinating the seeds. Then, plant the seeds in soil or in a starter cube. Once the seeds have been planted, care for them properly so they grow and thrive.

To plant cannabis seeds indoors, first soak the seeds in lukewarm tap water for 12 hours. Discard any seeds that float to the top. Then, place the seeds on a damp paper towel on a plate with 1 inch (2.5 cm) of space between each seed. Cover the seeds with another damp paper towel. Keep the seeds in a spot that remains between 70-80°F (21-27°C), and spray the paper towels with water whenever they start to dry out. The seeds will sprout in 2-3 days. When they do, fill pots or a growing tray 3/4 of the way with loose potting soil that has a pH between 5.8 and 6.3. Press the soil down lightly, leaving some air in it. Then, use a pencil to poke 1 inch (2.5 cm) holes in the soil. Place the sprouted seeds vertically in the holes and fill the holes with potting soil. Water the soil thoroughly and place the pots or tray in a spot that’s always 75°F (24°C) or warmer. Set up a grow light over the seeds and leave it on at all times. Water the seeds every day so the soil doesn’t dry out. The seedlings will emerge in 2-4 weeks. To learn how to use cool white grow lights to help your cannabis seeds grow, keep reading!

Set up your reservoir basin without nutrients and ensure that everything is in working order before adding plants and nutrients to the mix. This helps figure out any problems down the line by cutting variables during tests.

This method involves allowing the roots of the plant to dangle directly into a nutrient bath reservoir. An aquarium bubbler is placed into the reservoir to constantly aerate the water. Algaes are sometimes allowed to grow in this reservoir to add additional nutrients and enable filtration of the tank.

The main ingredients needed for a healthy plant are nitrogen, phosphorous, and potassium. These come in different blends at different percentages, depending on the stage of growth the nutrients are recommended for.

After all of this is done then the plants can finally be added to the set up without issue.

Using hydroponics to grow cannabis is not as complicated as it seems, but all the new terminology and techniques can be a bit overwhelming for beginners. For those who take the time to learn the system, the benefits are profound.

In general, a hydroponic grow won’t differ from a standard grow in most ways, aside from considerations needed to keep the tanks full and the room from getting too wet.
