i use MG moisture control , this is the 1st time i have ever used it ,, 1 day i was watering them & noticed very small tiny clear * tear drop * lookin bugs ,, i think they were aphids ,, crawling all over by where the stalk meets the soil ,,, , there were ALOT of them ,,, , anyways i startted over ,, BUT i used the same soil ,,, i just took about 15 pieces of charcoal in my grill ,, then took a big metal pot & put all the dirt into the pot & let it cook over the coals,, stirring it up every 5 minutes or so ... ,, well its been about 4 months since that happened & i check everytime i water & inbetween also ,, & have not seen anything since ,, my new baby is doing wonderfull now about to harvest in a week or 2 ,, BUT i will never use that soil again
