I am starting a new build and want to start right I was today to start with hydroton as a base layer. I was going to use small pebbles that I already had to keep cost down the hydroton is extremely expensive where I live is there a major benefit for it or something compatible? I want to do it right the first time and I am taking a list of plants with me when I go to the store that seem to be very common from everything that I have read on this site so I appreciate everyone that has posted what you have used.
