I "experimented" with this same question about seed growth. I took 2 seeds ( bag seeds ) that popped ( via the paper towel method ) and applied a SUPERTHRIVE mix using an eyedropper. The other I used a Rooting Powder ( dusted into the hole where seed will be planted.
One in a SOLO CUP ( rooting powder ) and RAMEN CUP ( SUPERTHRIVE ). They are 5 days old. They started poking thru soil in 24 hours. Growth has been noticeable and continuous. Soil mix used FFOF , nothing else. One does exhibit a slightly darker leaf but both are doing well. Light is CFL 100w ECOSMART bulb.
SUPERTHRIVE was added by an eyedropper ( 1 drop in 4 oz. Water. )
I haven't tried the Root powder way before but plant did ok. There is no stress or mutated growth. The SUPERTHRIVE way , I have done a few times before.
Experimenting is fun
