Thanks everyone, but with eco earth do I have to constantly moisten it? And what do you mean, proper husbandry?
I personally dont see any benefit to dry eco earth over other loose substrates if that is the route you wish to go, in fact I would go so far as to say that while safe, its entirely unsuitable for benefiting the Geckos lives. When dry, it doesn't hold any form of burrow, does not provide the firmness of substrate for which the Gecko is evolved to move and exist on, does not aid with shedding or the creating of micro-climates, etc etc.
There are far better options when it comes to providing natural substrates if that is your goal.
If I was to guess, I would say 'Keeboard' thinks if your care for your Leo is sufficient then it wont become 'impacted' from consuming tiny amounts of eco-earth over time. The reality however, is that if your Gecko was being cared for so poorly that such ingesting was going to result in impaction, consuming its prey alone would result in digestive issues.
PS: To clarify - Eco Earth, once soiled will need just as frequent replacing as anything else.
