this is the first time i have done bushes(2 bushes 1 indica 1 more sativa),i find that the more sativa the more open the middle better air flow and able to organise the bud sites,it has 32 big bud sites,the other is more indica with tighter nodes and more compact,it does not have a lot of airflow so i worry,it has 30 big bud sites.i put a 400 over the 2 bushes that are in the middle of a sog on each side with 600 over them.they are in a v,the midle of the 2 v,s is the bushes so they get hit from the side from the 600,s and then the light i find is not wasted.im not sure of the yield on the bushes compared to sog untill a week.my buddy grew a bush in hydro i find his nugs are not as tight and they do not taste like soil,and im all about the flavor.but with health restraints bushes are the way to go,but they drink almost 5 gallons of snow every 2 days each.and if you dont monitor i find that they can become nute deficient in a hurry,im finding the sativa dominant does not like to have its nitrogen cut back to early,but in smaller pots same clone it doesnt become deficient,go figure.but bushes are fun fun untill daddy takes the t-bird away.
