Starting some seeds for pepper plant to grow indoors this year and I have come across a problem. I have planted many seeds (over 20) and have waited over three weeks time for peppers to sprout and nothing... have a fluorescent lamp shining 16 hrs a day and a heat mat under them, overwatering/ underwaterig does not seem to be an issue. Seeds purchased from the hippy seed company (have had good results in the past) and Tyler farms (no experience). Pepper varieties planted: yellow bbg 7 and red bbg 7.
