that's retarded in this aspect, plastic grow bags are not going to "endanger" you plants any more than plastic pots, because they are cheaper. trying to cheap out can be costly in some areas, but this doesn't apply. so long as there the same size, one won't do too much better than the other, theyre both plastic and they both get pretty damn hot in the sun. plastic pots drain a little better, but they also have larger drain holes. could poke a few extra in the plastic bags if your concerned about that. Also plastic pots are much easier to transplant out of than bags. Pots will last longer than bags, but bags are easier to carry in(that is if your in the woods)
