But one thing they do… Starting seeds for hydroponics doesn't have to be difficult. In fact, it's really easy! Learn how to do it in 10 minutes with this Epic Gardening tutorial!
Best Way to Germinate Cannabis Seeds for Hydroponics
A lot of people are constantly put off when it comes to germinating cannabis seeds hydroponically. This is because of how time-consuming it is and how much effort it requires.
But one thing they do not know is that growing seeds in a hydroponic system will minimize the damage the seeds can get through other methods of germination.
What you Need for your Hydroponic System
First, you need to have a grow tray (not to be mistaken for grow tents) to hold your plants in a hydroponic system. This will create an ideal environment for your plants to grow in. Also, to avoid certain diseases and pests that usually comes along whenever a hydroponic system is set up.
Inside your grow tray, you should invest in a heater or heating mat to maintain a temperature that will encourage growth in your seeds. Aside from that, proper lighting should be installed as well to help your seeds sprout.
Another important thing to take note of is the pot where the germination will take place. You may want to buy starter cubes that can withstand being soaked for a very long time. Rockwool has got to be one of those products that will not dissolve in water.
Step by Step directions for ontogenesis Seeds during a aquacultural System
- The first thing that you should do is to soak your starter cubes or Rockwool in clean water for an hour. Once they have been given a chance to soak, place a few seeds into the cube’s hole. You may want to add a few more on each cube, just in case some seeds do not germinate.
- Once they sprout, you can take out the weaker or unsuccessful plants to allow the strongest to prosper instead.
- Prepare the grow tray with an inch of clean water or a nutrient solution that is not too strong.
- Arrange the light source and heating mat until a suitable environment is met. You can keep the lid on to stay the warmth and wetness within the receptacle.
- Place the planted cubes into the grow tray and add water or the half-strength nutrient solution.
- After regarding four days, you’ll start to see some sprouts emerging.
Apparently, some people prefer to use Ziploc bags, rather than getting grow tray when trying to get the seeds to germinate since it functions as a greenhouse. There is nothing really wrong about that. Just make sure to seal the bag with a little bit of air and place it in a dark place for four days to get the seeds to sprout. After that, you can put the starter cubes with sprouted seeds into the grow tray.
Another method is by using a paper towel. You can easily achieve this by following the steps below:
- Soak four sheets of towel in water. Once soaked, you must make sure that there is water dripping off of those sheets. Too much water is not good for the seeds.
- Set two paper sheets on one of the plates and place the seeds at least 1 inch apart from each other. After that, cover them with the other two sheets.
- Cover the seeds with the second plate to keep the moisture is locked in. Be sure that you check the seeds regularly to see if they have sprouted or not.
- This is where you will find out if your seeds have a chance to prosper.
Always be sure that the seeds are stored in a room where the temperature is maintained between 70 to 90 degrees Fahrenheit.
- Cannabis seeds usually sprout within 1–4 days. However, there are other seeds, older seeds to be exact, that often take up to a week to sprout.
- Whenever you try to check the seeds, make sure that the towels are moist. If the towels are dry, just add enough water, not too much.
You can understand that germination has occurred because the seed will split, and a touch root seems. Be sure that you don’t touch the taproot when it sprouts or during the transplantation process since it is very fragile.
Just be sure to use a paper towel that is nonporous. Using a porous paper towel will cause the cannabis seeds to cling to the pores of the paper towels.
Although you may not be successful at first, that is just part of life. You win, you lose; all that matters is
that you learn through these experiences. Even if you lose a few seeds in the process, you should not be disheartened by it since it happens to everyone — even if you follow the rules and step as meticulously as possible.
The Weed Blog has an article that directly compares traditional soil germination and hydroponics. Have a read at it if you are still undecided on what method to use; it might help.
Germinating through the process of Hydroponics is definitely a chore, but it is still worth it once you see the roots of your cannabis plants soaking wet and brimming with life. Once you succeed, you will be enjoying every hit you take from your own weed growth.
A Simple Guide to Starting Seeds for Hydroponics
You’re not alone — when I first started gardening, I was a soil gardener.
Starting seeds for hydroponics systems was unknown to me until I started to build deep water culture and ebb and flow systems. Once I built those, I had to learn how to start seeds hydroponically.
One of the main benefits of hydroponics is the absolute control you have over your growing environment. Knowing that, I didn’t want to germinate seeds in soil and then transplant into a my hydroponic system, adding a bunch of dirt to the system.
There had to be another way.
Here are just a few reasons why you want to start seeds in a hydroponic system as opposed to soil:
- Much cleaner than starting seeds in soil
- Seedlings grow faster after germination
- Easy to transplant into a larger hydroponic system
That second reason is a cool one. As soon as your tap root pops out, a hydroponic system is going to help it grow faster than soil and prevent it from becoming rootbound.
Step 1: Get Your Materials
You don’t need much to get started. If you build your cloner yourself, the rest of the materials will cost you under $50 bucks and will last you for quite a while. If you decide to go with a store-bought cloner, it’ll bump up the cost a bit but you’ll also be getting a much higher quality product.
Seed Starting Materials List
– You can either build your own or use something like the Clone King and starter plugs (#3 below)
- Seeds – find at your local nursery if possible, or buy many places online. A personal favorite of mine is RareSeeds.com
Step 2: Fill The Cloner With Water
Fairly simple step here. All you need to do is fill up your reservoir to just under where your net pots sit. Don’t worry about pHing your water or using reverse osmosis right now – standard tap water will be fine.
Step 3: Set Up the Air Pump
Place the air stone in the reservoir and connect the tubing. Connect the other side to the air pump and plug it in. You should see some beautiful bubbles start to come out of the air stone. These bubbles are what will keep the roots of your seeds moist and stimulate growth.
Step 4: Place Starter Plugs and Seeds
Soak each starter plug in some water and then place it in a net pot. The moisture will help the seeds germinate.
Drop 2-3 seeds in each starter plug. We use more than 1 seed because not all seeds will germinate and we want to make sure that every starter plug has a sprouted seed – otherwise we’ll have to replant!
Step 5: Maintenance
This system is very easy to maintain as your seeds sprout.
If you want, you can place a transparent cover over the top to keep in some moisture and increase the temperature of the system, but it’s not necessary.
Make sure to moisten the starter plugs with a few sprays from a spray bottle every day so your seeds have enough moisture to sprout.
When your seeds sprout, clip off all but the strongest seedling from each starter plug.
That’s it! Your seeds should sprout in 3-5 days for most plants and you’ll be ready to start growing some truly epic plants in your hydroponic system in no time!
If you’re more of a visual learner, I have a three part video series from my YouTube channel that goes into the entire setup in detail.
Part One: The Basic Setup
This is the visual version of the blog post. Helpful if you just need to SEE to learn (like me).
Part Two: Making Sure Seeds Germinate
This part of the series talks about some of the maintenance and troubleshooting you might run into when starting seeds, including the infamous “why do they keep falling over” problem that a lot of beginners run into.
Part Three: pH Water and Add Nutrients
This part of the series talks about the need to pH and add nutrients to your reservoir after the seeds have germinated. Because they feed off of their seed leaves at the start of their life, you can get away with not doing this until the seeds germinate.
By the way, I’m using the Bluelab pH Pen to fill all of my pH needs. It’s awesome!
