What DP said times 2...That's kinda a "hot" mix, so be careful with seedlings and watch for some burn early on, but it will work, especially if your re-potting regularly...just be very careful if you decide to add any additional nutes...very easy to burn plants using MG stuff...and I'd put quite a bit of perlite in it too! 20% maybe? and make sure your pots have very good drain holes!

DP...can I have your "old" avatar? you know...the one with the giraffe raising it's eyebrows??? LMAO! Where'd it gooooooooooo???? That one cracked me up every time I saw it! Very funny, but I like the Dead too!
