Seeds Haven’t Sprouted? 3 Easy Tips To Get You Growing
We’ve designed the World’s Smallest Garden to be as easy-to-use as possible. At the end of the day we are dealing with living organisms, however. Despite our best efforts, it’s impossible to guarantee 100% success. Sometimes nature just isn’t on your side – even if you haven’t done anything wrong! If your seeds haven’t sprouted the first time, the most important thing you can do is not give up – and try again.
Temperature / Humidity
Just like us humans, different plants are happiest at different temperatures. As a rule of thumb 70-85 F (21-29 C) is optimal for germination, although a lower range is fine later on.
One of the most common reasons for failed germination is that your seeds are too dry or cool. An easy fix is to create the World’s Smallest Greenhouse!
Simply take a piece of clear plastic wrap and an elastic band, and secure it over the top of your garden. If you have spare seeds, now would also be a good time to replace the original ones.
Just remember to remove the plastic as soon as the seeds have sprouted. Once your seeds have sprouted, they’ll prefer slightly cooler temperatures and a light occasional breeze can also be helpful.
Plants don’t need much light when they’re young, but once they’ve sprouted growth will be proportional to the amount of light they receive. Check out our separate lighting blog to learn more.
The World’s Smallest Garden uses capillary action to lift water from inside the bottle up to the seed. As long as the water level in the bottle settles to somewhere between the mid-point and bottom of the bottle then you should be ok. If the water is above the mid-point then the seed may become water-logged.
