Microgreens have become fashionable over the last few years. There are reports of indoor farms starting up in old factories and disused railway tunnels with enthusiasts saying this is the new, clean efficient agriculture which is better than messy soil. They fail to admit that nobody is growing root crops because they need soil!
The commercial growers generally use hydroponics, where the nutrients are dissolved in water which constantly circulates around the system. The nutrients used are soluble manufactured using the same energy intensive process used to produce agricultural fertilisers.
There are other ways to grow microgreens and we have opted for a ‘soil’ mix and an organic fertiliser based on seaweed. This could be a much more eco friendly way of satisfying the demand for fresh greens when it is impossible to grow outside.
The photo shows left-over pea seeds that were soaked over night and then just spread on the seed tray. That was 2 days ago, and they have sprouted already. I have never lost the fascination of seeing life created by just adding water! They will be grown on to the first true leaf stage which should take 10-12 days.
Next for seeding are Radish, Beetroot, Basil, Red Amaranth, Sweetcorn, mixed salad leaves and Sunflowers, Will it work? It should but who knows, so watch out for updates.
