Outdoors In Containers

Sup people i was wondering if some guerrillas could help me with a little problem..

Im going to be using 120ltr compost bags but have an organic prepper bed for them to sit on and not sure if i should still feed them with liquid ferts ?

I was thinking of using some bio bloom for 6 weeks then flushing for 3 weeks.. Or is there a more percific fertaliser for outdoors for bloom?

lots of factors go in to the answer. first gonna need to know how long there going to veg for. and what soil your going to use. id say yes your going to need to add fert. but only if you want large buds. but not completely necessary

Thanks. all sorted
