i have charleston grey,the first lot i put one seed per pot and left them in the green house,they are only just braking the surface after 2/3 weeks,i thought they had gone home,so as an experiment i chitted some more,along with butternut squash and gherkins,i put them on wet kithchen roll inside a tub with the lid on,on 4th,yesterday the gherkins got a little root,today with the extra heat from the sun the others got roots,much quicker than in the soil first,they are a heat and water loving plant,my next trick,is to get melons,she says living in hope.
