I see everyone doing these nice builds and after months of grow in time their plants are doing great and growing all over their great stuff. My question is how???? my last viv I tried with GS the plants would not grow on it and I dont know why. Is it mainly a light problem, is it what u put on the GS the humidity or what. Im thinking about redoing my bowfront I just built because its not doing nearly as good as i hoped and the waterfall was a mistake ( yet again) ill learn this time. but I cant decide if Im going to go GS or Dr Elseys Cat litter. Pros VS Cons?????
