starting more hyacinth bulbs in vases

A few more vases to use, a few are new ebay purchases and the small ones on the right I thought I would buy those small hyacinth bulbs from Sainsbury's but they don't have them so just using the bulbs I have. 1 pack of Aqua hyacinth bulbs left so using them for a bulb bowl. Socky keeping me company. At least one cat usually comes to the table when I'm doing bulbs.

bulb bowl with Aqua hyacinth bulbs, I have too many bulb bowls and nowhere to put them so just using 1 this year, the bowl and the vases are filled with water to just below the bulbs and put into the dark for a few weeks

Sternbergia lutea which I am not sure about. I've not grown them before so not sure what to do, especially as the label says they bloom Sept / Oct. Well I only just received them! Do they go into the dark like hyacinths? Do they stay out? I've put all of them into the dark except that on the left which looks like it has a flower bud in the stem.

Before I decided to put them in the dark I had put them on the windowsill, two of the stems broke off in transit. I hope they recover.
