Good luck with algea . HC will melt down . DSM is not good way for HC
I guess I failed pretty badly eh?
Next time do not set yourself up to be proven very wrong.
A few thousand folks have done extremely well.
Common mistakes: sealing the tank up too much, it's better that it's not 100% humid, leave some opening, just enough to get a little condensation.
I can grow HC outside in full sun in California's dry weather if I water daily. I have had it growing on my bonsai. Freezing temps kill it though.
Poor CO2 is the most common killer once people flood their tanks, the DSM avoids the CO2 issue, so any one should be able to grow a nice lawn in while dry, but the DSM saves NONE if they cannot grow HC well submersed, which are quite a few folks.
I'm not one of them.
