Expectations In My Total Yield

A customer has a question and I hope we can get some opinions on it, thanks.

“I have a few questions. If I plant 5 jack herer seeds in a 5×5×7 indoor tent and I follow your guide through the process, what should I expect my total yield to be from all 5 plants?
Also, what is m2? Square meters? I appreciate your help. Thanks.”

If it is your first time I would plan on around 2oz per plant. But it really depends on your setup.
Yes M2 is meters squared.

Again there are many variables that will effect
Your yield so it’s hard to determine what one will get.
