Hi Charles
Following your methods I’m growing peas this year for the first time in modules indoors – and given the weather I’m very glad I decided to give it a go! They are growing in 4cm modules, 2 to 3 per module. Ten days after sowing the tallest have grown to 7cm, whilst others are just peeping up through the soil, and a few roots are showing through the holes in the bottom of the modules.
How long can they remain in the modules before transplanting outdoors?
Best wishes
