Enclosed wooden box with a 40 watt bulb on a dimmer. Adjust the dimmer to maintain 80F.

They don't need light to hatch and don't need heat unless it drops down below 18 dc (though I've had them at 15dc no problem).

However the higher the temperature the faster they will hatch and grow.

Light is needed, to trigger the hatching. At 80F I get a good hatch rate in 24 hours. Check out http/www.brineshrimpdirect.com/res-hatching-c169.html

Bbs is going for around $22/lb shipped. I'm going to get every penny out of a can.

According to this site it the bright light that helps.

Tolak it correct, taken from the link.
buffering in soft water), temperature (80-82o is ideal), light (bright light is part of the hatching trigger) and gentle aeration (which keeps the unhatched cysts from settling to the bottom). Aeration should be gentle, not vigorous. Avoid an airstone (it would rapidly clog, anyway), since fine bubbles may trap the nauplii with surface tension.

That's what you would think, all other branchiopods depend on this, that way the cysts don't hatch when buried feet under mud.

However Artemia are able to hatch at a much lower level of light, the dark corner of a room will suffice, I didn't mean like a total blackout though, just that they don't need their own source of light.

The reason for this is probably because in the great salt lake and other large habitat the cysts float giving you large eggs slicks which are like big massive floating mats of brine shrimp cysts, In these mats the cysts underneath the ones at the top (and the ones underneath those ones ect.) receive much less light than the top cysts .

Bright light will will probably speed up hatching, just as it does with other branchiopods, however this usually has more to do with the heat from the light than anything else.
