IMHO, if you water from the top the perlite might continue to be moist for a couple of days, and it didn’t happen with my hempy cups so i dunno what to tell you. Anyway, grab a chair bro, not this cycle but next i will be doing an automatic grow with hempys using MBBR. Already looking on the web for where to get them in black, don’t want any light going into the roots… Thanks @Skiball.
That is exactly how i am doing with the Dark Devils i got running bro.
