That advice is better for an experience grower. A new grower is unlikely to have any idea how to tell the difference between healthy and infested clones.
How True, working on my third grow, traded some MOB clones for WW, ended up with spider mites, I was lucky and caught them in time,was able to save the rest of the grow room
It doesn't like to change genders even when STS/CS is used and, if it does revers, the pollen is not viable.
Don't get me wrong, MOB is a nice smoke - it's rare to see that much potency in a strain that tastes that good - but the cut definitely comes from some severely inbred genes. I miss it every now and then - but then i remember that i had to veg it for about 8 weeks (or about 10 weeks from cutting) to get more than an ounce per plant.
