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

  1. 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.
  2. Once they sprout, you can take out the weaker or unsuccessful plants to allow the strongest to prosper instead.
  3. Prepare the grow tray with an inch of clean water or a nutrient solution that is not too strong.
  4. 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.
  5. Place the planted cubes into the grow tray and add water or the half-strength nutrient solution.
  6. 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:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.

Conclusion

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.

Grow Guide: How to Start Cannabis from Seed

Starting cannabis from seed is an affordable and fulfilling way to start growing. It all starts with germinating cannabis seeds, followed by creating the ideal warm, humid environment for seedling growth.

Giving your seeds (and then the seedings) the best support from the very start, you’ll set yourself up for success come harvest. Here are the basics to growing cannabis from seeds.

Where to Find Cannabis Seeds

At this point, there are hundreds of different online options for sourcing cannabis seeds . If you are growing indoors, the world is your oyster, as many websites are willing to ship nationally (or even internationally). Plus, if you master the indoor environment, you can recreate perfect conditions for even the most demanding of strains.

For those growing outdoors, try to locate a local breeder who also cultivates outside. These cultivars will be adapted to your unique climate and will likely produce better results.

No idea where to start? Seed Finder is an excellent resource for sourcing specific genetics and breeders in your area. But this is just one place among many in today’s weed-friendly world.

How to Germinate Cannabis Seeds

What You’ll Need:

  • Cannabis seeds
  • Paper towel
  • Plate or tray
  • Ziplock bag
  • Heating mat (optional)

The first step to growing cannabis from seed is learning how to germinate them. Place cannabis seeds on a sheet of paper towel, laid on top of a tray. Dampen the towel with water so it’s wet but not soaking.

Fold the towel in half to cover the seeds, and enclose it inside a Ziploc bag. Place the entire tray on a heating mat, the top of a fridge or other warm area of your house. Cannabis seeds germinate between 71 to 77°F (22–25°C).

Check back every day for signs of life. If your seeds are viable, they should sprout within a week. If you are still waiting for a few to emerge after a week, toss those and begin again. If no seeds have sprouted, your seeds are no longer viable.

Ed Rosenthal recommends soaking seeds for 12 hours before germination. His formula uses water, a cannabis rooting solution and hydrogen peroxide.

This solution is a good option for commercial and large scale growers, as it reduces the risk of fungal infection and encourages rapid sprouting. Compost tea is another excellent option for a natural alternative.

Ideal Conditions for Cannabis Seeds and Seedlings

What You’ll Need:

  • Germinated Cannabis Seeds
  • Potting Mix (or Root Riot Plant Cubes )
  • Propagation Tray with Dome

Once germinated, you must carefully move these tiny seeds into the soil or soilless growing medium like Root Riot Plant Cubes. When you start cannabis from seed, the aim is a warm and relatively humid environment.

Starting Cannabis With Soil

If using soil, choose an organic potting mix suitable for seeds and starts. Water soil mixture before use, and fill potting containers that have a drainage hole. Avoid pellets that are commonly sold at garden centers, as they don’t retain moisture well, and it’s challenging for cannabis roots to break free of the netting.

Using a popsicle stick, tweezers or a toothpick, lower the germinated seed into a premade hole roughly two the three times the height of the seed. As you gently fill in the hole, be careful not to damage the sprout.

Starting Cannabis for Hydroponics

For hydroponics, you’ll want to use Rockwool cubes or Root Riot Plant Cubes. These come pre-cut into perfect starter plugs, often with a hole in the middle for the seed.

Before use, soak the cubes in water and rooting solution until they are wet but not dripping. Gently lower the germinated seed into the hole using a popsicle stick, tweezers or a toothpick. Be extremely careful not to damage the early sprout.

Whatever option you choose, keep the seedlings at a consistent temperature: 68 to 77°F (20 to 25°C). Depending on where you live, a heating mat may be necessary. Use a propagation tray with a clear dome to trap the humidity in, but open up once a day to encourage a bit of airflow.

Lighting Requirements for Cannabis Seedlings (& How to Eliminate Stretch)

Seedlings and starts require 16 hours of light a day and eight hours of dark. You can even bump this up to 24 hours a day, and the seedlings will continue to eat it up.

What kind of grow light do you need for this early stage of development? Not the same capacity you’ll need for veg and bloom. Higher wattage types of HID lights (Metal Halide and High-Pressure Sodium) are far too powerful for sensitive seedlings.

Most growers use a simple LED grow light or a CFL fixture. Ed Rosenthal recommends 40 to 60 watts per square foot.

While these may not be entirely enough for veg and bloom, they produce enough light for seedlings without the added heat. This means you can place the lights close to the tops of the seedlings.

Place lights as close as possible to the tops of the starts, without raising the temperature over 77°F. You want seedlings to get enough light without burning them.

The goal is to avoid early stretching in your small cannabis seedlings. Healthy seedlings are short and wide, not tall and skinny. Stretching is when the sprout reaches tall for the light without putting out leaves.

Typically, under outdoor conditions, plants remain short for the first few weeks as they focus energy on building structure and root development. Stretching inside demonstrates the seedling is not getting enough light. The light source is either not intense enough or too far away.

When to Transplant Cannabis Seedlings

The primary goal for starting cannabis seeds in small pots is to encourage healthy and strong root development. Once the seedling has three to four sets of leaves, begin checking root development. This will likely be three or more weeks after germination.

Another telltale sign it’s time to transplant is when you notice roots begin to creep out from the drainage holes. If working with Rockwool, a key indicator it’s time to transplant is when the roots begin to outgrow the cube. A plant’s growth trajectory slows down if it is root-bound. If the roots have consumed the available space, it’s time to move up a size.

Cannabis Seedlings From Germination to Transplanting

Starting cannabis from seed gives growers access to a much larger genetic pool than what you can find locally from a clone supplier. Plus, if you’ve got the time to invest, it’s a much more affordable way to grow cannabis. Finally, if you are already set up with a veg and bloom room, you have everything you need to get started from seed.
