heddyuh Posted February 23, 2023 Share Posted February 23, 2023 Hi guys. I purchased root tabs, but I am struggling to keep them under my very thin layer (1 inch or even less) of coarse gravel substrate. I imagine my rooted and stem plants are not going to like it too much either (I'm trying to grow dwarf hair grass, Italian val, crypts, and hornwort). I'm 100% going to buy more substrate to increase the height of of it so I can at least get a 2-3'' layer (that should be thick enough for my 5 gallon right?), so I was wondering what you guys recommend. Should I just buy more coarse gravel? I heard root tab nutrients will leak out if the substrate is too coarse, so I don't know if I should opt to find a finer substrate and mix it with my existing one. If anything, I would prefer fine gravel rather than sand or dirt if it'll still play well with the root tabs. Any suggestions are greatly appreciated 🙂 thanks. 1 Link to comment Share on other sites More sharing options...
Administrators Cory Posted February 23, 2023 Administrators Share Posted February 23, 2023 I recommend just buying more of the matching gravel. Link to comment Share on other sites More sharing options...
nabokovfan87 Posted February 23, 2023 Share Posted February 23, 2023 Agreed. I'd try to get at least 3" thick layer of substrate. 1 Link to comment Share on other sites More sharing options...
