Will they survive?

So the plants basically cooked for about 20 hours. My brother was doing some plumbing for the chiller fan and stupidly did not turn the water intake back on, thus the plants cooked at about 40 degrees for about 20 hours..

Will they survive? They are bone dry and the leaves crispy and i watered them a lot, previously were completely healthy and growing fine, in about 3-4 weeks of veg.

Thanks for your input.

Cheers.

Well, all you can do is hope for the best. They're a pretty tough plant, some may survive. Good luck.
