i have heard of soil being baked in the oven.but that would be a real pain.sorry thats not much use at the minute,more the next grow.but maybe cooking soil kills all the good with the bad to?
me being in a fairly cold place in the world,we dont seem to have many bad bugs round here.but as its a problem i dont want to have im very particular about keeping soil indoors and tools are only for canna not house plants or outside.but i understand thats a difficulty for you.
as it seems to be a pretty bad outbreak of bugs,with lots of hatching eggs in the soil everyday.even if we kill everything today by tomorrow how many more babies have hatched and are crawling up to the surface of the soil ? could be a running battle untill harvest.
and then 20 of the wee feckers could be hiding inside of some ducting.
i grew for 6 months and didnt get enough for 2 joints a plant that whole time,was close to giving up the growing.im only a lil bit better of a grower 4 years later,but glad im not smoking no name no taste no smell street weed.
we face some tough times as growers,some very good times to,and sometimes a kick in the balls.
i dont know what the answer is,i dont know what to do,but we gotta do something we cant quit.
