how long does pollen stay alive before its non viable to a female? like say i grew 4 plants, i forgot to check on em, then all dropped nut sacks and dropped all their pollen
i vacuumed but everyone knows its small and impossible to get it all


How long before it would be safe for females in flower to be in their and pollen couldnt make babies per say?






Also is it possible to do a wierd hydro system?


No pumps but i water it, and for the soil-less mix i would use a mix of polymer crystals some rocks *cant remember the name...*


I want to do this because exchanging soil every 2 months would be a pita... and bleaching and then flushing with water would be way easier...

or can you bleach soil too ? or would that be like poison to the plants

i see how it is *corner*:sadcrying:

Pollen can still be viable a couple of weeks after release.
A mellow solution of bleach/water will sterilize. (2 tsp:gallon, I believe)
Spray all non-living things in growroom, and wipe down. Lamp and hood should be cool and unplugged before spraying...cleaned and dried before use.

About hydro...not a technique I use, nor one that I care to use.

Don't bleach the soil.
