Bazarocka.... I had my seeds in the dark and they sat there in the rapid rooters a little to long and i was using a regular house bulb to use for light for a couple of days till i went and picked up the t5. when i got the t5 everything exploded. right now my blueberry mom is looking great. she is going to be the next run. Now i know this is hydro but i am sure everyone has some experience with dirt so what kind of soil mix would i use. what is the good stuff.
