I really do appreciate your help, and although it is alot to take in at first I love the fact that i can actually find a live person to help me! Your right about the "deodorized" fish emulsions- GAG! I used some on my trees yesterday and gagged a couple times haha!
My tallest one is 2 inches (picture). And the kitchen gets around 6 hrs of direct sunlight, probably not enough. As for the temp in the kitchen, I may have a heart attack if it ever gets that cold haha! I like a set 75. My peat moss is an organic jiffy mix and says "In california and georgia, this mix contains 48-50% peat moss, 48-50% vermiculite and lime, and organic wetting agent." Im pretty sure it has no perlite in it. Is that something I should buy? Thanks for your help!
