First Grow - Blackberry Kush

Well, it's my first grow! This grow diary is about one Blackberry Kush, even though there will be some company to get cozy with. All seeds are fem, non-auto. I have always wanted to grow Blackberry and have high expectations! (Pun intended.) Just to keep things interesting I have included a mystery plant. While doing some cleaning, I found 12 or so seeds (at least 2+ years old). Curiousity has me including the lone seed that germinated out of the dozen. After all, I must have kept them for a good reason? After startup the humidity went up to 95-97%, but from research & reading about early vegetation stage it's ok. The other concern is the high temp which is odd since I'm using fairly low-powered LED lighting. The moisture being generated in the 40" x 40" x 60" GR is very tropical. For this first grow 4 different plants are being grown together in a cozy sea of green (well, 5 maybe including the mystery plant if it's a she): Blackberry Kush Fem (This Grow Focus), Super Skunk Fem, Gold Leaf Fem and last but not least two hybrid "Hazy Gorilla Time" (Gorilla Glue #4 x Clockwork Orange x Malawi) from Regs, so unknown but hoping for at least one female. Low (3 out of 5) success rate of germination average across the board; seeds were put into cups of water for 24 hours, then the sprouts were placed carefully into AgroMax starter plugs & put under dome for 2 days. All "keepers" then transplanted into 2 gal. pots for official "Day 1" of the grow. Thankfully I am lucky to have a guru who steered me to Great Lakes Soil and liquid gold SuperThrive; why be a mad scientist when others have done it for you?
