This info was tough to get, as a bunch of companies distract you with smoke and mirrors but the reality is this is what will hit the shelves on the date of legalization. Any companies promising a July 1 completion date for facilities will only have product hitting the shelves by October 2018. These listed companies will see 2 cycles of sales at minimum before any expansions see their first harvest. Please feel free to send in a correction if you have a link to back it up.
