Thanks for the very interesting answer. I also thought that this substrate is not exactly the best, in fact I am gonna replacing it with pure dry sphagnum moss. When I published the post I had already cut the floral stem. The vase has holes underneath but the problem with this foam is that it is not a material that absorbs water and retains it, if you were to remove the water from the sponge it would in fact dry in an instant, so I assume that the fact that the plant grows so slowly it is due to the absence of oxygen in the substrate, and as if the roots were immersed directly in the water. having said that, is it possible that in conditions in which the roots are submerged in water, the plant is unable to grow as fast as a normal substrate? As far as water is concerned, I think there are no problems, I use reverse osmosis demineralised water, but to be safe, I'm already proceeding to buy a TDS meter. My doubt was due to the fact that I've always read that Dionaea grow well only in acidic substrates, I didn't know they could stay in a neutral pH. However, as you have been able to observe, the problem may not be the pH but the fact that the roots receive little oxygen in this type of substrate.
