Plant-count questions answered: how the formula works, indoor vs outdoor, and why the maximum is rarely the right target.
By a formula in section 325 of the Cannabis Regulations that converts your authorized daily amount (grams per day) into a number of plants, with separate figures for indoor and outdoor growing. Your registration certificate states the number.
It scales up quickly, and indoor allows more than outdoor for the same amount. Rather than memorize it, use our calculator — move the slider to your daily amount to see indoor, outdoor, and combined counts at once.
A big outdoor plant is assumed to yield more over a year than an indoor one, so the formula allows more indoor plants and fewer outdoor plants for the same daily amount.
No. A higher count means a bigger, costlier grow and more scrutiny. In 2026, inflated amounts are a leading cause of refusals and revocations. Aim for what your practitioner can defend.
That is a serious compliance violation that can cost you the registration. Always count honestly and stay within the number on your certificate.
No payment to find out. Transparent, tiered pricing should you choose to proceed.
