Ok, time for what most professional use. Hydro isn’t really that difficult either, it just takes a little more work to setup, has the highest set up cost (though it’s the cheapest indoor method long-term), and there is a lot of bad information out there. But if you want to get the best out of your cannabis plants then hydro is the way.
While soilless is a hydro system, most refer to hydro they are talking about a re-circulating system where the plant’s roots are actually submerged in water. The most common setup is called a DWC (Deep Water Culture). An air pump is installed so oxygen can be pumped into the water and provided to the roots.
- Despite the roots being underwater, they are actually provided with more oxygen compared to the other two methods.
- Err on the side caution when giving nutrients since they will be circulating throughout the system and more readily available to your plant.
- After setup, growing in hydro is just as straightforward as the other growing methods.
