The plants are growing like and hell and some plants more than others. I therefore have to super-crop the plants, which is a method promoted by SOMA from SOMA-Seeds. I take the stem of the plant at appr. 20 cm under the top, directly above an internode, and squeeze it hard between my fingers. So hard that I can feel the fibers brake inside the stem. I squeeze in a circle around the whole stem and then bend the stem sidewards until the whole top of the plant is bent 90 degrees to the side or even points downwards. This way I dont have to top the plants and save the big top buds. The stem will heal and the plant will continue to grow, just at a lower height. I use this method since many years and it works GREAT. The BIO-TABs nutrients still do thier job VERY WELL, all plants have a healthy green color. The SANlight EVO4-120 LED-lamps are still hung at 75 cm distance from the top of the pants and do an OUTSTANDING JOB.
