@Kingjoe83 Im intending to use my little 2x2 tent for any males i find (once i get my 4x4 up aswell) but there are little hacks to get around it. When you find a male strip her down to like one main cola. This way you aint checking eeeeevery main for when they gonna crack cos as we all know female buds on a plant dont mature at the same time. Males are no different. When you feel they have swollen enough and you feel they are close chuck a milk bottle with the bottom cut off around her like one of them dog collars and chuck a see through bag over the top. Now he shouldnt contaminate your females when he pops and you can just take him outside and take the bag off to check how hes progressing... and also keep collecting pollen through his flower cycle.
As i said though this is a work around not a solution. Things can still go wrong and you could still contaminate them. Only 100% guarantee is quarantine.... n even then its only 98% cos you could carry the pollen on your clothes or the wind could change and the pollen could carry into your grow room some how lol
