little over an eigth?! wtf dude. his plants are 3 feet tall and they usually grow alot bigger during Flower time. and you think itll give him not even an ounce? my lowest guess is at least an ounce. good luck dudehow much they will produce depends on alot of things. nutrients, watering, plant type, and just the invironment there in. I would say that you could get maybe a little over an 1/8th maybe more. do you have any pics of your plant?
two to three a plant is average, 4 oz a plant is doing really good, but out side can yeild a lot more a plantaverage indoor plant should have about 4 ounces minimum...
some plants can produce pounds apon pounds. its all in how you grow from start to finish. some people just have the perfect secret method.
