Growing onions in water

[rary]

I came across a reference in a post recently about growing onions the same way you grow hyacinths with water I want to give this a try, so what feed would I need to add to the water for onions to grow

I've started onion sets off with the base just touching the water - that worked. However, once an onion bulb gets wet it stinks.

What does it smell of?

Well have set up two sets and one seedling, but might try more, and thanks for that info. VC I will try to avoid the bulb touching the water, and will let you know how I get on with them, I am taking photos to record how it goes

Its smells of "stink".

Must be a bit like growing Hyacinthaceae in bulb trainers. They also stink for a different reason (and sneezing fits), but can just see us all with row after row of glass jars with onions growing out of them....

Ohhhh . how about a strip of plastic with holes every 150mm, placed over a gutter with ends on it. Just add water and "seaweed".

Start marketing them... 1m gutter, 10 onions and grow bar....
