hi i just had a couple ov babies pop and using miracle grow....wondering why you think its no good ? thanx
I can give a couple reasons.
First of all, there is an entire industry revolving around selling you what is, in effect, overpriced dirt. So naturally there are those who have an interest in convincing you that the cheap stuff you find at Walmart can't *possibly* be any good, as well as those who need to convince themselves that their expensive dirt is the only way to go.
Next, since its cheap and easily found, Miracle Gro is usually the first "go to" product of complete noobs; people who have next to zero experience gardening ANYTHING. They make every classic blunder (overfeeding already nutrient-rich soil, overwatering/underwatering, bad lighting, etc) then have terrible results, blaming it on the soil.
Again, I'm not saying Miracle Gro is great, and there definitely ARE better soil mixes out there. Just that if you know what you're doing, its perfectly adequate (and yes, I've used it myself more than once, and I've never had any issue or problem with it).
I'd also point out that there are SEVERAL types of soils carrying the "Miracle Gro" brand name, including a "moisture control" mix that is basically a true soilless mix with coco coir and peat moss. I haven't tried that one yet, but at least based on the contents, it seems like it could be a good choice.
