These are great! Ive bought seed mixes before from bunnings with not much success but these are a different story. nearly all of them have shot up, within 7 days too.
Now i have to try hard not to kill them :))
I put them in a seed tray with seed starter mix and kept them moist with a spray bottle, i also covered the tray with glad wrap and left it sitting inside a window.
