Today I’ll teach you how to set up your hydroponic reservoir for growing cannabis, and I’ll show you what you need to do each day for optimum growth 🙂
Have you seen cannabis plants growing with their roots just floating in a reservoir of water? This type of hydroponics is known as Deep Water Culture (DWC), and has been around for over a 100 years! As more growers gain experience with this medium, DWC has become increasingly popular for growing cannabis. Hydroponic setups are really neat and offer some big benefits over growing in soil!
- Grow Environment – I personally recommend a grow tent as opposed to building your own environment from scratch.
- Grow Light – If you don’t already have a grow light, I recommend getting a 250W, 400W or 600W HPS grow light for your first grow. They are the most consistent type of grow light and get really great results in DWC.
- Nutrients – I highly recommend getting GH Flora trio, Calimagic (Cal-Mag supplement) and Hydroguard.
- Seeds – Learn where to get seeds
- DWC tank – Learn how to build your own (it’s surprisingly hard to find a pre-made tank considering how cheap all the parts are!)
- Hydro usually takes more preparation/setup than growing in soil. You’re providing more for the plant instead of letting the soil do some of the work for you
- It can be easy to get root rot in hydro if you don’t provide your plant with a good-bacteria supplement like Hydroguard.
- Soil-grown buds may have a more complex or stronger smell than hydro-grown buds, especially if grown in composted living soil without any liquid nutrients
- Growing in soil is more intuitive for many people, and some people already have experience with soil from other types of gardening!
Hydro is a no-brainer for me. Whenever I go back to a hand-watered grow like coco coir, I am always surprised by how much extra time it takes to water plants and remove the runoff. The most intimidating part of hydro is just getting started – after that it’s actually really easy to take care of your plants. In my opinion, hydro is far easier and less time consuming than growing in soil or coco coir once you’re set up. If you are interested in hydro, go for it! If you follow this tutorial you will succeed!
- Takes more time and effort to set up than soil or coco
- Buds grown in soil without added nutrients tend to have a stronger smell than buds grown with liquid nutrients like in a hydroponic setup (though if you’re trying to keep things low odor this might be a benefit).
- Unless you protect your roots by using the right supplements and equipment, your plants may struggle with root rot. Luckily if you follow the steps in this tutorial you don’t need to worry about root rot killing your plants!
