hi madrasandy,i start them off inside and then once the plants have a few leaves i move them to the greenhouse,which was towards the end of march last year,the plants always seem to look healthy but like i said the chilli's always shrivel up and die but the plant still look healthy,last year i tried jalapenos,puya and serrano,this year i am trying cascabel and jalapenos again,i have been known to pick a chilli of the plants before they are ready,i will not do that again,also my greenhouse does not have a heater,do you think i need one?
