Hope it works well! Just watch for that initial ammonia release! LOL But I'm sure just plants will be fine with it. Good luck!
I think part of my decision to not go with ADA was for a 72" x 18" foot print tank with 2-3" of soil would be a stupid amount for me to spend! LOL
I hear you on the cost! Before I actually looked at substrate cost I figured I would go with Tropica, as Dennis actually mentioned how expensive ADA soil was in one of his articles. But here in Canada, it seems the price is exactly the same as Tropica or only a couple of dollars more. Maybe it's import fees? Either way, if I was going to drop coin on Tropica, might as well be ADA.
I have read about the ammonia spike, so I guess it'll be two WC per week for a month or so!
