When I grow in soil, I don't ever use anything that has any nutes in it at all... I prefer to be in charge of what nutes my plants get and when... but that's a personal choice.. It sounds like you've used the BioBizz Light before so you know it... go with what you know instead of trying to learn something new and maybe screwing it up! If at some point, it doesn't seem to work for you, you can try something different - but since you've got some, use it! And fabric pots are the absolute best.... Good luck!

i prefer soilless substrates, but the location doesn't matter much in that choice. use what you have.

I will use same combo + biobizz nuts
