jcrabbit Posted December 1, 2022 Share Posted December 1, 2022 I am building out a 40 gallon Petco tank. The bottom has an area of approximately 600 square inches. I am trying to get a sense of how many carpeting plants to buy, but I'm having trouble finding a guide on it. For example, let's say I want to use dwarf hairgrass or pearl weed as the carpeting plant. Let's say the rule of thumb is to break a pot into 8 pieces and plant each piece one inch apart. That'd require 12.5 pots per 100 square inches. But is that the right approach? Of course one can always buy less plants and wait for them to grow in. So I know the answer is more or less "it depends on your budget." But I'm curious to hear how people estimate the amount of plants to buy. I'll also be getting plants to put on rocks and wood as well so I'm also curious on how to guesstimate how much to buy when it comes that scenario. Though I'm still trying to educate myself on what kind of plants are appropriate there. Thanks, John Link to comment Share on other sites More sharing options...
