Hydroponic systems are either active or passive, depending on the way they are designed. Active systems involve the movement of nutrient solution using electric pumps and the oxygenation of water using air stones. Passive systems are much more simple, and some rely on capillary action instead of electric pumps to deliver nutrient solution.
Perlite is a volcanic glass that expands when exposed to high temperatures. It’s often used in garden soils to provide aeration, which is exactly why it’s beneficial to use as a hydroponic growing medium for cannabis.
Types of Passive Hydroponic Systems
Rockwool is another popular choice, and is a substance created using volcanic rocks with a wool texture, hence the name. Rockwool has a tremendous capacity to retain water, which allows for good hydration of the upper root system. Rockwool can be placed within a hydroponic basket, but can also be lodged directly into the top of a bucket or tank lid without.
Hydroponic plants require the same nutrients as their soil-based counterparts. The easiest way to go about feeding your plants is by purchasing hydroponic nutrient solutions that contain all of the required substances for both the vegetation and blooming periods. Products will also describe how often to add nutrients back into your system and how much dilution is required.
Hydroponic cultivation might initially seem like the result of modern advances in technology. But this couldn’t be further from the truth. The origins of growing plants in water goes back thousands of years into human history. The famous Hanging Gardens of Babylon, created in 600 BCE, are theorised to have utilised hydroponic principles. The region located next to the Euphrates was naturally dry and arid. It’s believed the crops of the garden were nurtured using a trickle-system starting at the river.
One of the reasons why you should want to increase THC is it includes the mental and psychoactive effects experienced when using it.
This is important information because you need to keep a constant eye on pH levels.
It is important not to rush this process. You need to be patient and your patience will be rewarded.
How To Maximize The THC In The Bud?
Ultimately, irrespective of what product you use, it should contain the macronutrients, potassium, nitrogen, calcium, phosphorus, magnesium, and important micronutrients such as manganese, zinc, iron, boron, Molybdenum, chlorine and copper.
This method delivers the nutrients needed directly to the plant through the mediums for growth, and since there is no need for massive webs of roots, neither does it need the extra energy to take in nutrients, the process is faster.
If it is your first time starting a cannabis garden, you might want to decide whether to use a clone or a seed.
The advantage of this is that you can customize a growing season and encourage plants to flower exactly when you want them to.
I’ve tried a bunch of different germination methods over the years, and the technique I prefer is for hydroponics is starting with the “Paper towel method” to germinate, putting the germinated seeds into Rapid Rooters, and installing the Rapid Rooters directly into reservoir. Lots of other germination methods as well, but this has worked best for me!
Don’t use a humidity dome on seedlings unless it’s very dry where you live. If you do use a dome, consider keeping a vent open and watching the humidity. A young seedling doesn’t require high humidity, and they tend to get “wet feet” and stop growing in constantly wet conditions.
Most seedling plugs will go back into place easily, and you’ll barely be able to tell it’s been opened 🙂
Here are tips for taking the best care of hydroponic marijuana seedlings:
Just like in soil or coco, cannabis plants in hydro grow fastest when it’s a little warm, around 75°F!
