Miracle Grow?

[privet01]

Miracle grow is mostly nitrates, which come from urea and ammonia. But I don't think that's a problem in small amounts in your soil/substrate or on the foliage of the plant.

BUT...........

The problem, IMO, IMO, IMO... is that if you have a water feature for your amphibian, then is that going to be leaching into the water?? Nitrates will quickly make your water unhealthy for your pet.

You could just do foliar feedings and just spray the plants being careful where the overspray goes. Or maybe after using it to water your plants, give it a couple hours to let whatever is immediately going drain into the water do so, then change your water.

If your viv does have a water feature that your plants sink roots into and your pets spend time in the water, then I think like KMAC stated that your amphib's will be making fertilizer for you with their poo. You can use those test strips for aquariums to get an idea of your ammonia/nitrate levels. I don't fertilize, and I do notice that when the ammonia levels are getting high in the water some of the plants really perk up and grow, but when I change the water their growth slows.

If your viv does not have a water feature, or your water feature is physically separated from the water by a divider or barrier, then light use of Miracle Grow or other is probably less of an issue.
