I would have loved to buy my plants from forum members because the folks on this forum are experts for sure plus I feel good supporting them.All tanks are works in progress. You may start with one set of plants and end up with a completely different one.
Personally, I buy plants that are cheap from trusted sellers on this forum. I shop a little bit almost every time I log on.
Done, done and DoneI would set up a scape in mind that you're trying to achieve. Pick out your favorite foreground, mid ground , and background plants and then setup a list of plants to order. Research all plant requirements wether it's high light, co2 mandatory, growth rate, etc.
