Fox Farm product question

I know Fox Farm make a product can grow big.....and i know they make one for soil and hydro watering systems.....what i what to know can you use the one for soil in a hoydro systems.....the numbers on the gorw big is 6-4-4......but remeber this is for a hydro watering setup.....and if i can use it how much do i use cuz the directions is for soil so i dont know how much use.....

No idea. My guess is they make two formulas for a reason. Grow big is the only product they have with a separate formula for soil versus hydro.

The hydro grow big is 3-2-6, so you can't switch one for another because of the different ratios. The feeding schedules use different products at different times for soil and hydro, so I don't know what to say.

Here's a link to the schedules in case you don't have it:
