Hello thatguy..do you have a real name?
If you want to grow Tonina, I at least got to know the name :wink
Okay. No I am not saying you "cannot" grow Tonina in Flourite, I am betting you can, I did for a couple of year's, I just didn't know Tonina very well at the time, and did not take the time to read the plant.
I know a guy who grow's Tonina, Erio's and other demanding plant's in plain ol silica sand., with root tabs, that's it, and they look good!
once you see them grow in acid, man, you never really see them the same again
Tonina's do not have much of a root structure, unlike most Erio's.
So most all of the plant intake is thru stem/leave's, and with a healthy Tonina, there are alot of leaves on a single stem.
Need good strong light, abundant C02, plenty of nutrient's, all of them, dicipline, and patience... reading the plant's is the key.
What are you're water parameter's?
and what material equipment do you have to work with? everything!
Do you have an RO unit? not that it is an absolute necessity...but.
now I am going to go over here and tinker with my tonina for a bit..
