Propagation question

[Casual T]

Greetings all, I am a relatively experienced grower, but due to an unusual set of circumstances i'm a bit worried about my young 'uns. For reasons which I wont go into, i can't do anything with my plants for three days time. They are in a prop chamber under cfl lighting, about 1 inch from the top of the chamber. My concern is, that some of the bigger plants are touching the top of the chamber. Are they likely to come to any harm due to this prior to the weekend?

Cheers!

What you should do is raise the light so the tallest plants are 2" away and put blocks under the shorter plants to raise them up to the same level.
or
The leaves that touch the bulbs could get burnt , you can also use a fan to blow on the bulbs/tops of the plants to prevent any burn if the bulbs were to touch the leaves by chance.
