if your DIY burner is too hot the sulfur will catch fire and burn off
if you use an aluminum cup and all the sulfur burns off your crop will die from aluminum oxide poisoning - oh and that could kill you as well
do yourself a favor and dont cut corners that could kill you, your crop or burn your house down
Id rather spend 100 bux and have peace of mind
Thank you,
Has anyone ever burnt off all the sulfur completely? It may be possible, but I've never seen it happen.
If your manufactured and purchased sulfur burner is too hot the sulfur can catch fire, so again I think the point to be taken is to KNOW WHAT YOU ARE DOING.
Aluminum oxide poisoning? So to all of those driving vehicles with alum block engines, watch out!!! Don't want anyone dieing from exposure to heated aluminum.... :damnhippie:
Seriously though, consideration to the ideal temp at which we 'burn' sulfur (in our cans with heating element) the threat of an aluminum oxide being burned off is, well I'm going to say it, nearly impossible imo.
If one still has reservations, use stainless steel or some other metal.
