Ok, so I'm guessing the answer to this is "it depends" but how many plants should I buy initially for my new 40 gallon aquarium? The closest quality non-big-box store is 60 miles away and I get up there 1x per quarter if that so I don't want to under or over buy. I have 60/40 ecocomplete and gravel with 79w of T5HO light. Also is there any carpeting fore ground plants suitable for beginners I should look out for?
