In other words, 1) "what is not funded in science doesn't exist", 2) "sometimes you obtain the desired result by luck or rogue factors that are unrelated with your desired explanation" Speakers have big magnetos, for example. Other team could repeat exactly the same experiment and conclude that "magnetic forces stunt grow". 3) "sometimes only the 'correct' results can be published, so people repeat the experiment until being convinced of their results" and 4) "yes some scientists are liars" I will add a 5) you may favor desirable events and ignore undesirable ones without even realizing it (provide better care to one group, water for a few seconds more each day or have two different people caring for different groups)... ... Because unplanned events and lab accidents happen. I assume that having big speaker boxes near plants may trow a temporary shadow on them each day. If it happens in your lunch hour you could never realize it. And this things happen in science. All the time. I would suggest to put a couple of turned off speakers of the same size near the quiet group and repeat the experiment.
