Yea end of july sounds about right

yeah, you definetly need to check the amount of sun that it is getting. The cannabis plant automatically controls its own flowering by calculating the alteration in the number of hours of daylight and the uninterrupted darkness at night. Most mature plants will be begin flowering when the photoperiod changes to 12/12, however the photoperiord is genetic with the type of plant you are growing. Talk to the seedbank you got your stuff from for any further info on the strains, (good choices btw.) Hopefully that gives you a good estimate of when to return to your patch.
