"whatever they would need to grow"

Growing stuff requires hydrogen in the form of water, oxygen in the form of water and carbon dioxide, carbon in the form of carbon dioxide and nitrogen in the form of nitrates or ammonium compounds as the main components of your biomass. Unless these are available on the target planet (I'll assume that minerals such as potassium, phosphorus etc. are) then every gram of biomass that you want to ever have in your colony has to be ferried there. It's not like colonising a new land on Earth where you can expect to tap into the existing stuff that's already in circulation.
