How to Speed Up Seed Germination With Stratification

I’ve been having trouble getting my spinach to germinate. This prompted research Seed Germination Temperatures. I learnt that it was just way too hot in Kuwait for spinach to germinate at the moment. Furthermore some seeds need to be exposed to frost, or low temperatures, to germinate. Yet many countries doesn’t experience frost… and thats when you should “stratify” your seeds.

Stratification is essentially emulating frost temperatures with modern technology such as fridges and freezers. It’s a great option if you live in countries that just don’t get cold enough to otherwise germinate the plants, yet not so hot that the plants can’t grow as seedlings.

Seeds that take 2-3 weeks to germinate will often germinate faster when stratified first. Too slow of a process could mean that the seeds don’t get the ideal moisture from the soil (if growing hydroponically this usually isn’t an issue), and reduces the risk of growing mould and other diseases (can be an issue when growing hydroponically).

Here is a great video from YouTuber MIGardener that talks about how and why to stratify your seeds.

I attempted the technique that MIGardener teaches (video above), and it worked! I was about ready to give up after 3 attempts to get my spinach to germinate had failed.

My grow room is now reaching around 26°C (78°F) during the day; when the temperature is at 77°F rates drop to about 30% and can take a week or longer. Using the stratification technique allowed me to grow the seeds earlier than normal (whilst it was still too warm for the seeds to normally germinate), and gave me a 100% success rate!

Have you tried statifying any seeds? What is your success or failure stories for seed germination? Share with me in the comments below.
