Bring some GroChar seed compost and potting compost into the greenhouse so it is warm when you sow seeds or transplant overwintered seedlings.
Starting seedlings off at this time of year can be quite tricky, not only because you need heat for germination, but because of the low levels of light.
The Grow Light overcomes these problems. The canopy is height-adjustable so that it can be positioned close to the plants and gradually moved up as they grow.
Get ahead with planting by growing seeds in guttering. Soak peas overnight in water then almost fill a length of gutter with GroChar seed compost, arrange the peas on the surface and cover with compost.
Do not water until the pea shoots are showing. When pea plants are 5cm high they can be slid out of guttering into a shallow trench in the garden.
