I have my HC growing emersed for anout 2 months and it is growing painfully slowly. I am fairly confident that I have the nutrient side of things down well. I have some growing and some burning. I am using a mix of seedling soil, sand and a light dose of chicken manure.
I am using foam boxes with glass on top and allowing air to mix through every few days and another 2 cultivators. One foam box is sand and seedling soil, another foam box is seedling soil, sand with a light mix of chicken manure on top which is holding ok.
The other 2 cultivators are a mix of seeling soil, mushroom compost and dymanic lifter (pellet form chicken manure) which is done for and I expect to be dead by tomorrow.
