Ive known a lot of people, newbie growers, Having huge dreams, hundred plus plant operations, but by the end of the season they end up with almost nothing worth smoking. Inexperience is a big issue in a big grow like you are attempting. You gain your experience through small scale grows, once you learn the basics, have your method of growing down, then begin to go more large scale. I can see you wasting a lot of time and money and yeild very little. One guy mentioned 60-100 pounds, That will never happen, being a new grower. Your expectations are way to high, you should try aiming for at least one ounce per plant. But you wont even be able to do that without proper soil amendments. You should grow what normal people grow, and thats a few plants for personal smoke, not dream of a forest of weed plants that you can make money on, because it won't happen. And I assume you have animals in the area your growing, so you will need to purchase fencing, chicken wire fencing works good, and wrap it around each plant, To purchase that amount of chicken wire fencing, your looking at an easy minimum of several hundred dollars, not including any soil amendments, insecticides and fertilizers. To do, what you are trying to do properly, you would need a budget of thousands of dollars, thats the only way the plants would amount to any potential. Stay small, learn the basics.
