one of those tote box's is quite small to grow multiple pumpkin plants. Ive never grown indoors, but outdoors, given a full growing season, its quite common for pumpkin vines to reach 25-50 feet. Giving that small amount of space, I think it would be almost impossible to yield one pumpkin from one plant. If your pumpkin plant was growing properly, it would only take 3-4 weeks and one pumpkin plant would fill the inside of an entire totebox, they grow big quickly, I do not even think you could yeild a single pumpkin in such a small growing area.
