4) soil is a 50/50 mix of sunshine mix #4 and
OF with the middle core of SSM#4. I like the look of the SSM#4, very light with plenty of chunky perlite and very few sticks.i don't belive this has any kind of pre-charge and it comes in a bale like promix, so it needed to be broke up.as for the core I put a round bottle in the pot and filled up with the 50/50 mix spraying PH 6.5 water every couple of inches and lightly tamping down until I'm about 3-4 inches from where I want it to be. spinkle some mycro in straight SSM#4 and fill the hole up, spraying PH water every few inches. then fill up the pot with SSM#4.
