While the peas i sowed directly into the ground in the veg plot didn't come up the ones i put in an indoors nursery tub did come up a treat and were now big enough to transplant into the veg plot. This is always a risky business putting the young plants at the mercy of the outside world and its millions of slugs but they can't stay indoors forever.
I've sowed a second batch in the nursery tub as a back-up / second crop just in case. I really need a green house to be honest.
The porch does suffice to some extent, my peppers are starting to grow.
