Hi All, I have been using for a number of years a similar set-up.Using an old Polystyrene Chilly bin ( Esky , Cooler ) Seeds planted in any available plastic trays, Seedling trays from garden shop. Chinese takeaway food trays ect. With a low power 15watt oven light bulb as heat source.I start them in August (Southern Hemisphere) to plant out in October This works well and will germinate many flower and vegetable seeds if you wish. Once started I put the seedlings under an old fish tank fluorescent light in the hot water cupboard until they are big enough to put near a window. Watch out for sunburn on the seedlings as the sun gets stronger in spring Tony Flynn Grandad Retired by the beach Bay of Plenty , New Zealand ----- Original Message ----- From: "Byron" <byronbromley@tellink.net> To: "Chile Heads" <chile-heads@globalgarden.com> Sent: Wednesday, January 25, 2006 1:51 PM Subject: [CH] Seed Starting heat source > Here's a heating set up that you don't even need a Master Card to make > > The Thermometer is the most expensive single item at about $5.
