Just started an outdoor guerilla grow, new to growing but could do with tips along the way. Growing in the south of England. 10 sweet skunk auto's, 5 Think Different auto's, 5 northern light autos and one La frutta di vinus auto. Using 5/1 compost to perlite mix in 13 litre pots with bat shit at the bottom. planning on putting more nutrients when they're a bit older. All 21 have germinated and looking well will post pictures. got home made propagators for the first week or two and slug pellets and planning on adding copper rings. Pics soon, any advice welcome.
