??? My plant club says Swords are heavy Root feeders and once I added Root Caps my dwarf Chain Swords exploded.
I think I'll take Tom Barr's words as truth. He also recommends CO2. But I use it when I can. Still manage to grow easy plants. Med-high light stuff really needs it for sure.

These are straight sand tanks. I used Root Caps and Leaf Zone. Nothing else in the early days of these tanks. Excel was added ? If I remembered 1x a month ??
These are 10g tanks so easier to grow in.
I do not deny your experiences or that of your club members but this does not make it true. I have yet to see any concrete scientific studies on the subject but this does not make it untrue. For every claim there is usually a counter claim (plants grow just as well in inert substrate with EI dosing) for this reason I tend to not to state either for fear of perpetuating regurgitated myth.
