Benefits of Hydro Over Soil.
How to Grow Cannabis in DWC.
Differences Between Soil & Hydro.
Growing in coco coir can be considered a type of hydroponics since it naturally contains no nutrients and you must provide all the nutrients in the water. However, when you say “hydroponics” most people think of this:
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 🙂
Hydroponics is when you grow your cannabis plant in an inert medium like coco or a reservoir of water, and provide all the nutrients to the plant directly in the water.
When it comes to hydroponic cannabis…
Cons of Hydro.
Is Hydroponics Good for Growing Cannabis?
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!
Pros of Hydro.
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!
So there are five major parts to getting set up. You need….
Cons of Hydro.
Once you’ve got your gear and supplies, it’s time to get set up and start growing! Here’s a quick overview.
Hydroponic cannabis involves growing the plant in the medium, where it develops a set of roots and a stem. The roots grow through the medium and into the nutrients. You use a small pump with a timer to fill the bottom layer with the nutrient solution. After an allotted period where the plants are fed and watered, the timer shuts off the pump, and the solution drains back into the reservoir.
There is no ‘right’ lighting set-up, only the best one for your grow space and budget. For example, if you have a large room with excellent ventilation and airflow, you can purchase High-Intensity Discharge (HID) lights.
Nitrogen, Phosphorus, and Potassium are the essential nutrients, however. Most solutions contain 15% of each, also known as a 15-15-15 solution. If you grow weed in temperatures below 80 degrees Fahrenheit, you need higher amounts of nitrogen. Other possible solutions include 20-20-20 or 23-19-17.
There are several hydroponic gardening systems to choose from, and all of them are suitable for growing cannabis indoors . Regardless of the method you use, the overall tactic involves using a reservoir containing the nutrient solution. You then place it beneath a growing tray. This tray holds the inert growth medium of your choice, such as sand, gravel, or Rockwool.
Regardless of what you use as a growing medium instead of soil, you have to apply a nutrient-laden solution to the roots. The water that isn’t absorbed by the roots gets recycled through the system for later absorption.
However, in reality, you can engage in marijuana growing with hydroponics using something as simple as a few pots containing the inert medium. By all means, you can opt for a more complicated option, but it requires significant set-up time and a ton of maintenance.
There are many indoor hydroponic systems to choose from, but we will only focus on the best known.
It’s easy to underestimate the difference a few pH points make. The pH scale is logarithmic to the base 10. Therefore, water at a pH of 5.5 is ten times more acidic than at 6.5.
Hydroponic marijuana refers to a means of growing using a soilless system. In other words, you cultivate plants using an inert growing medium and nutrient-rich solutions. Previously, the assumption was that hydroponic set-ups were complicated and expensive affairs designed solely for commercial growth.
It is best if the water flowing through your system is at a temperature of 65 degrees Fahrenheit. This is the ideal temperature for nutrient absorption, and it also prevents algae buildup. As for your growing room’s temperature, keep it at 75 degrees Fahrenheit to begin with.
When using the Wick System, choose smaller plants because larger ones require a lot of water. They could also potentially use the nutrient solution faster than you can supply it. Bear in mind that the Wick System is also the least efficient and may produce the smallest yield. However, you are less likely to encounter problems.
One of the most significant problems with this system is that the water solution could fail to leave the tube, stagnate in the channel, and kill your plants. This is why you need to make sure the tube is cut at a steep enough angle to allow for easy passage of the water.
How to boost quality and yield…
Deep Water Culture (DWC)
NFT is a complex system and involves pumping your water solution from the reservoir to your planting tube. It is common to use large PVC tubing angled at a slight decline. This tactic ensures that when the water drains down the pipe, it passes by the roots of all marijuana plants before it gets recycled in the container.
There are hundreds of cannabis strains widely available online. However, we feel that the following five provide a nice mixture between being relatively easy to cultivate and providing a high yield:
Nutrients such as calcium and magnesium are absorbed at a pH of above 6.0 in general. However, the likes of manganese and phosphorus prefer a slightly lower pH. In a hydroponics system, you are solely responsible for adding nutrients directly to the root zone via water. As a result, significant fluctuations in pH are more likely than in soil. It doesn’t take long for it to become a problem.
Growers who have a system in their basement often make an elementary mistake. They place their nutrient reservoir at the side of the grow table. When they need to ‘flush,’ they find that a bucket is the only way to drain their tank.
The hanging root structure of the plants means they are exposed to air constantly, and the result is a crop of flourishing plants. Your cannabis plants can use their energy for the sole purpose of maximizing growth. With soil, they waste energy trying to find air, food, and water. This is why marijuana grows so spectacularly in a well-designed hydroponics garden.
