Ok so I've had the gnat problem with my 9 day old malana bomb auto.. I bought some mosquito dunks and crumbled it in the dirt... And placed six stickys around them.. I also bought a bag of sand and dug up 2 inches of dirt.. I saw my plants white root and it started to fall over a lil bit.. It wasn't broken off just leaning a lil. I dug the dirt out with a spoon and placed two inches of sand... Now my bug question here is will my plant grow in sand? How will I know to water my plant since now there is two inches of sand? Do you think I dug to deep if I saw the white root? Also a little dirt landed on a node that is growing some leaves and I can't get it out even by blowing.. Will that harm it? Please let me know what you guys think.. I'm a little scared about all of it. Thanks guys.
