Hello I have researched the pumpkin starting methods and have become very interested in your method. My only problem is the hills are too far away from an outlet for the heating cables. Do you think I will be able to get good enough results without the heating cables or should I start them indoors? Are there any other methods of keeping the soil at about 70 degrees without heating cables? I've seen water filled protective covers in garden catalogs would they help? Thanks for any info John
