Im getting about 1. gram per watt with opium a little less on my Trainwreck.Ive found topping early on increases yield 20%.Those tables take some time to get down but the yield would be more than my soil ,Im growing seeds now and these are going to be five footers,If your running sea of green you should look at cindy99bx1s over on thc farmer,These seeds flower in 50 days and would be great in those tables.Your yields will improve with your skill. and number of grows.Anything I can help with just hollar................Peace
