Growing your own food is extremely rewarding! In this blog we take look at the basics of germinating seeds.
Germinating your favourite plants from seed is a great way to start a garden, it does require a little patience as some seeds can take much longer than others to germinate so, it is always a good idea to do a bit of recon beforehand so you know some basic facts about the variety of plants you’re about to grow.
Tip: Temperature and Humidity is probably the biggest factor you need to pay attention too.
What Equipment Do I Need To Get Going?
- Grow cubes (Rockwool cubes) or Growing Medium (Coco or Soil)
- A Good quality Rooting tonic
- Mixing Jug 1L- 5L
- Propagation Dome / Humidity Crib
- Hygrometer (Optional but advised)
Heat Mat & Thermostat (Optional but advised)
Below Is A Step By Step Process For Germinating Most Seeds
- Pre-soak your grow cubes or sponges in a root tonic. We use in a mix of Ryzofuel(0.75ml) or Regen-a-root (1ml) per 1L of water.
- Prepare Propagation kit (base and lid).
- Connect Heat Mat underneath Propagation Kit. (If you have a Thermostat controller connect this to heat mat after and place probe inside propagation Dome)
- Remove cubes/sponges from solution and give a gentle squeeze so the cubes are not saturated but are still holding a substantial amount of solution.
- Place your seeds “pointy” end facing down and push in so the husk of the seed is about 1-2mm under the hole surface level.
- Close all the vents to achieve 100% Humidity, after they have the seeds spring to life open the vents on the Dome this will lower humidity to 72-75%
- Most seeds will germinate around 18-22°C - Chilli for example require the temperature range 26-28°C before they ‘pop’ so always check beforehand.
- Put a Hygrometer inside your propagation room this device measures the Temperature & Humidity which will allow you to calculate your VPD
Don’t Be In A Hurry, Take Your Time.
- Most of the time the seeds will pop open around day 2-5.
- Once the seed has germinated the first 2 sets of leaves will be round. These are called cotyledons, the first set of true leaves will be the following pair.
- Some gardeners prefer to leave the seedlings in the propagation dome until the 3rdor 4th set of true leaves appear. This is a matter of preference; just don’t be in a hurry the seedling stage can be a slow one.
- For the first few days after transplanting, top feed your plant food mix to ensure the seedling is receiving adequate amounts of food most brands will indicate a seedling stage for feeding.
