The 10 gallon Low Tech continues to grow slowly. Cryptocorynes, Nymphaea, Ceratopters, are all doing well. The Helanthium tenellum has a runner with six (6) plantlets and still growing. I added a Barclaya longifolia on 6/22 and it is doing well, not only are the existing leaves larger but it already added a new leaf. The most exciting thing I spotted today was new growth from below the substrate on the Pogostemon erectus. I've had stems branch before when I 'topped' them but seldom new growth generated from the roots zone. The stems were a little shorter than 3" when planted and are now over 6" with much larger, healthier leaves along with the new growth.
