Seed germination supports play a crucial role in the early stages of plant development, providing the optimal environment for seeds to sprout and grow into healthy seedlings. These supports include a range of materials, techniques, and conditions that aid in the successful emergence of a plant from its dormant state. From specialized substrates and containers to controlled temperature and moisture levels, the selection and implementation of germination supports are fundamental factors in agricultural and horticultural practices. In this context, understanding the various types of germination supports and their tailored applications is essential for ensuring robust and thriving plant growth.
Seed germination with Jiffy pot
They are immersed in water and waited until they swell (being a pressed troba enclosed by a soft net it absorbs water like a sponge) they are wrung out to remove the excess water, so as not to risk the seed rotting. At this point, make a small hole in the center, 1-2 cm deep, where you place the seed and cover it with the same peat. We place the disks, with the seed inside them, in a mini-greenhouse suitable for germination and close the lid to encourage the increase in humidity. Keep the mini-greenhouse at a temperature between 18°-25°C trying to keep it as constant as possible.
Check the humidity of the jiffy every day if you notice that they tend to dry out, spray water with a common spray bottle that vaporizes. We wait certain days (depending on the species germinated) and as soon as we see the sprouted seedling which has reached a height of 2-3 cm we can place it in the substrate without removing it from the support

Seed germination with rockwool cubes (Gordan)
Wet the rock wool cubes for a few minutes with an acid pH solution and a product that stimulates the roots ( Gaia radix ). squeeze out a little excess water, the cubes must be wet but not soaked in water. Carefully place the seeds in the holes at the top of the cubes, without going too deep.
Finally cover it with some wool threads. Close the mini-greenhouse to encourage the increase in humidity, essential for germination. Never leave rock wool cubes with water in the tray. Risk that the seed rots. Keep the mini-greenhouse at a temperature between 18°-25°C trying to keep it as constant as possible. Check the humidity of the wool cube every day. If you notice that they tend to dry out, spray water with a common spray bottle that vaporizes. When the seedlings show roots in the lower section of the rock wool cube, it is time to plant them.
Rockwool vs Jiffy pot: the best way for cannabis seed germination
Rockwool cubes and Jiffy pots are two popular choices for germinating and starting seeds in horticulture. Rockwool cubes are made from spun volcanic rock or basalt, resulting in a lightweight and porous medium that provides excellent aeration and moisture retention. These cubes offer a sterile environment, reducing the risk of soil-borne diseases and pests. Additionally, they have a neutral pH, allowing for precise control over nutrient solutions. On the other hand, Jiffy pots are biodegradable containers made from compressed peat moss or coir. They provide a natural and organic alternative, allowing for easy transplanting as the pot itself can be planted directly into the soil. Jiffy pots offer good moisture retention and breathability, supporting healthy root development. However, they may break down faster than rockwool cubes, especially in wet conditions. Ultimately, the choice between rockwool cubes and Jiffy pots depends on specific gardening needs and preferences, with rockwool cubes excelling in controlled hydroponic systems, while Jiffy pots offer a sustainable and convenient option for traditional soil-based gardening.
