I normally sow my tomatoes around about the 21st of Febuary. (Today.) But this year I am going to wait another 5 or 6 days as I have found out what with having a cool greenhouse (Only got a parafin heater) that the tomatoes once germanated sort of sit there in the potting compost for about 2 weeks or so until say the middle of march then all of a sudden they start to grow like the clappers. So instead of allowing them to sit there and do nothing this year I am going to sow later. That way the chances of getting fungus or a rot on the seedlings should be smaller because they will not be sitting there doing nothing. The quicker the growth the stronger and healthier the plant. Thats my opinion anyway :)
