i am growing in rock wool cubes and today when i was checking my ph i noticed a little white worm on the base of my stalk.

the worm i found have a black dot on the head and seems to be right next the seeds/seedlings. I'm not sure exactly what they are since ive never seen them before.

i cant find anything about worms in the forums. Some stuff gives incorrect info. looking for serious help.

maybe a fly laid some eggs in your rockwool?

What you speak of are fungus gnat larvie. the love wet and warm places. you can buy some type of insceticide or put a slice of potato by therockwool they will go and feed upon it then just throw out the potato when they nestle in it. get some sticky fly paper to kill the adults and try to let your rockwool dry out a little so they die. you can also but some red wine or beer in a shallow cup. they will be attracted to the fermentation. hope that helps. :smoking:

it sure does and next time i have that issue ill do just that. what i did was take the seedling out of the infested rockwool and replant it in a good one. No shock or anything and its doing great. i had to kill 2 plants (SSH) though since the roots were already eaten. sucked and it hurt.
