These photos are of a red spider mite eliminator, safe towards humans but not nice for pests.

The products vaporises a special sulphur to kill ,but is safe for humans it is claimed by the manufactures. Used extensively by commercial growers, and first brought to my notice by the Carnation website.
The second shows a simple propagation cover which is to prevent wilting of new un-rooted cuttings, easier and quicker, than ploybags.Cuttings can be seen and state of health etc determined by eye alone, which polybag covering can preclude.
