I made a thread a few weeks ago about how awful the Sta-Green potting mix that I bought is. I planted 2 tomato plants of the same strain (looks like some type of roma, the name starts with an M), both in 5 gallon buckets, one in Sta-Green and one in Miracle Grow to do a side by side comparison. Both were practically identical in size when I transplanted them and have gotten the exact same treatment, fertilizer, and sun, the only difference being I skipped 2-3 waterings for the Sta-Green plant because it seemed to be holding more water. Here is an update, the Miracle Grow plant is doing very well, while the Sta-Green plant looks awful. Maybe when they said grow vegetables twice as big, they meant in comparison to their other shitty potting soil Sta-Green, in which case, that claim appears to be true.
BTW, I know there is another forum for growing non-chile plants, but this thread is about potting soil, not growing tomatoes, that's why I'm posting it here. I don't have any chile plants I can use to do a side-by-side comparison so that's why the picture is of tomato plants, but the point is to compare MG and SG potting soils. It's not the greatest picture, and the color of the plants probably can't be seen very well, but the MG plant is also a darker shade of green while the SG plant is a little on the pale green side as well.
Edit: I clicked insert media, but it didn't work. Let me try again...
