Makes humidity super high and softens the husk, making it easier for the plant to shed it. You can also spray the plants with water, but I have found the cups to be more effective.[\QUOTE]
I thought that might be the case. Humidity in the veg cab can fluctuate from optimal ranges to as low as 20%rh so I can see how a dry spell could cause the husk to become fused on. Because that sucker is on there tight!! I knew I would damage it trying to force it off so I haven't bothered, just figured I'd wait and see what happens. One of the others managed to get the first leaf set out despite the husk keeping the cotyledons pinned together vertically. It was an odd sight for about a week but now I couldn't pick which one it is out of the bunch so it doesn't seem to have been negatively affected by it. I'm definitely going to try the cup trick when I get home and I'll report the results.
