Most likely not. That's alot of dirt. I have seen a guy on here doing a sog setup with 3 plants in 1 gallon pots. They go in the soil as soon as they root and are flowered and dead in 50-60 days. Not enough time to cause any real problems. I myself am using window boxes. 24"x6"x8" and put 3 plants per box because they are from seed and have a large root system already. When the clones are ready they will be 4 to a box because they don't have such a massive root system....
