With clones and small plants, you can kill spider mites and eggs before putting in your grow room. You need a garbage can with a loose fitting lid.. Put the plants in the bottom of the can.. Add a couple pounds of dry ice, not touching the plants.. The dry ice will sublimate into co2.. Overnight will kill any living thing.. I've left plants in for 24 hours with no harm to the plant..
