Hey i know this is an old thread but ive found the same thing in a few orders i bought in between harvests. (I like to try a few strains before buying seeds) anyways, im just curious what everyones thinks because im not sure how the perlite would be inside buds grown in hydro? Ive grown for a while, in soild before switching to hydro so im quite familiar with perlite. The little pieces ive found inside the bud absolutely resemble perlite, i just havent heard of very many people growing hydro in perlite. I suppose i HAVE heard about some people preferring to grow in a hydroton/perlite mix or in a coco/perlite mix but it seems to be an uncommon thing IME. Considering all of this, im just not sure how perlite can be making it way up into the buds in the first half of flower, especially without being noticed. Any thoughts?
