Looking for some free seeds? Many genetics companies and seed vendors will give out free stuff at various times for various reasons. Here's a couple pointers for getting free or heavily discounted seeds:
Attend pop-ups and events that are cannabis related. Vendors give out free stuff as part of marketing at these events, and it lets you meet some of the owners and fellow fans
Join site forums and chats for various companies - they give out free seeds in a separate promotions page including members of the month, bud of the month, and various contests
Email the genetics company owners directly and ask if they need any beta testers!
