Now that it’s legal to grow your own weed in dozens of states, many people are beginning to grow their own marijuana plants. Before you can start growing you have to get a marijuana plant!
There are two ways to get a marijuana plant, get a clone from a trusted source or start some marijuana seeds. Marijuana seeds can be expensive so it’s important to have a solid plan when germinating cannabis seeds.
There are various benefits of hydroponic seed germination, but the process has to be done correctly in order to get your cannabis seedlings to grow healthy and vigorous. Starting seeds in soil has its tricks too. However you decide to grow, it all starts at the seed.
Creating Cannabis Plants For a Hydroponic System
The most essential part of starting seed for a hydroponic system is the medium that your planting into. There are several types of media, and the one you choose to start your seeds should work well with the hydroponic medium that you will be planting into once the seed has grown.
For example, if you plan to grow your plants in a Rockwool media starting your seeds in Coco would not work well. Starting seeds in soil for a hydroponic wouldn’t work well either.
It’s best practice to start the seeds in the same medium that you plan to have that plant complete its life cycle in. Each medium will have its own requirements for starting seeds. It’s good to have a process that is tailored to how you like to grow.
The Benefits of Hydroponics in Your Life if You Grow Cannabis
Growing cannabis in a hydroponics system has a lot of benefits when it comes to indoor growing. Starting seeds for hydroponics can be a bit more challenging than soil.
One immediate benefit is you can avoid the concern of picking up diseases from store-bought marijuana plants and spreading them to your hydroponic garden.
Once you get the hang of how to germinate cannabis seeds and tend to your hydroponic system, you’ll never want to grow seeds through any other growing medium.
Hydroponics will give you better germination rates, faster vegetative growth rates, and increased yields compared to soil growth.
Turning Quality Seeds Into Cannabis Plants
The first step is making sure you have quality seeds. Finding quality seeds can be as easy as going to your local hydroponic store or ordering from a trusted online seeds bank.
The second step is to choose your media and create your nursery environment. The nursery environment should include the essentials: oxygen, water, light, and heat. As you start seeds in the nursery, the proper lighting and the right temperature are crucial.
What Every Cannabis Seed Needs
In a cannabis plant’s life, there are four main components. The amount of these components will change as the plants grow but they will always be a requirement. these essentials are oxygen, water, light, and heat.
As long as you supply these essentials and use them in an organized manner, you won’t have to do a lot of work after the initial setup.
A Simple Beginning that Anyone Can Do
Let’s begin the process of designing your first hydroponic nursery system starting small.
You’ll need a grow tray, some starter cubes, a starter tray, a humidity dome, and a heating mat.
Starter cubes aren’t necessary, but they do make a difference. They have the ideal nutrient solution, like peat pellets, to help those first seeds sprout and grow.
Place the starter tray in the grow tray, place the starter cubes in the starter tray, place the seeds in the cubes, place the humidity dome over the top of the tray with everything inside, and place the entire setup on top of the heating mat.
Adjusting the Temperature
For your role, you have to monitor the temperature and humidity. Temperature is regulated with the heating mat and humidity can be added by putting a small amount of water in the base of the grow tray.
The humidity dome will help keep a high humidity for the seedlings and their roots. It’s equipt with vents that you can use to regulate the temperature and humidity inside.
The heating mat under the grow tray helps avoid cold temperatures from messing with the starter cubes and the seedlings. But if the room is already warm, like 80F, be careful not to overheat the dome.
The heating mat keeps the grow tray at the ideal temperature to nestle the seeds inside and encourage them to grow. Keep the cubes moist, but not saturated, and you should have plants in a couple of days.
Finding the Right Light Source
Now that the dome setup is complete and supplying a proper amount of oxygen, water, and heat it’s time to focus on the lighting.
Too much light will stress and potentially kill your seedlings, while too little light can cause them to stretch and become very weak.
We recommend using a LED fixture with about 30w of lighting output. Placed about 12 inches from the top of the dome, this fixture will allow for excellent seed propagation and beginning growth.
T5 lighting fixtures also work great for starting clones when placed about 6 inches above the top of the dome.
Sprouting Your Seeds
Now that your nursery environment is set up, it’s time to start the process of germination!
First, take your starter cubes and let them soak them in clean tap water. Once the cubes have soaked, place them in the starter tray with one seed per cube.
Second, place the planted seed in the nursery environment, and in 48 to 72 hours your seedings should being to emerge from the cube. Over the next 10 days, that plant will grow into your beautiful baby marijuana plant.
Get Ready to Transplant!
To ensure your germinated seeds can successfully grow into cannabis plants, you will need a hydroponic system to transplant them into.
It doesn’t have to be fancy, but having the system ready and a plan in place will increase your chances of success and a bountiful harvest.
When you can see roots daintily hanging out of the cube’s bottom. It’s the moment you’ve anticipated since you started your germination process. It’s time to transplant your young plants!
Chances are, it’s only been a couple of weeks or less, but it can feel like forever as you’re checking and double-checking the plant’s health. These plants are still small and delicate. Make sure your environment is going to be optimal for the seedlings while they take root in the new hydroponic system.
This article is the simplest way to germinate seeds, but there are a lot of other techniques that people commonly use, Such as the paper towel method, using rockwool cubes, coco mediums, and soils.
To learn these other methods and more we will be teaching a hands on propagation and cloning class at our store in Rapid City, SD on November 5th. More classes will be scheduled in the future too. If this is something that you would be interested in participating in you can contact the store at (605) 348-2358.
How important is the VPD during a DWC bubble pot grow with Auto flowers.
Since roots are dangling in water and absorbing nutes do you really still need to pay attention to you RH and VPD. I wouldn’t want to drown my plants on the top side, with a high RH and VPD, since they are being saturated on bottom. Don’t see a lot of growers mention this. Do you follow the VPD values just like you’re growing in soil or coco?
