Rootbastic?

Hello has anyone used Rootbastic? either the sample or the real products.... first of all can i use it if im using Great White for my roots, Rootbastic is used the first 1-3 weeks as well, also it says 0.3-1ml, how much is 1ml is liquid i usually use 1tsb etc!

1 Tablespoon is 15 ml, a teaspoon is 5 ml, you want 1/8th teaspoon which is about .6 ml

i got a sample of rootblastic and boomblastic awhile ago.. i didn't really see much difference from either one of them tbh.. as for how much is 1ml, not much, lol.. there is 5 ml's in a teaspoon, so one ml is 1/5th of a teaspoon..
