Miracle-GroLiquaFeed All Purpose Plant Food Starter Kit

I have an expanding hose, would the unit fit onto a brass fitting?

What ratio of feed it uses? eg. for 10 litre of water, how much ml feed is used?

Anyone know what1 btl feeds in real life? - I've seen 45sqm but this must be a mistake as it wouldn't feed my small veg patch even once

Further to last question. what strength would i need based on using 5g per litre per sq yard
