Day 121 since being cloned. Three weeks of flowering complete, six to go. This plant occupies one of the four spots under the main LED, in fact Black Rhino is likely getting the most light in of the tent. Some branches have developed much faster than others. You can see bud sites clustering. Most recent feeding was 2-7-7 Shultz Cactus plant food with a popsicle stick dip of blackstrap molasses.
Oh ya, one of the few growers I see doing black rhino. Looking really good and I look forward to seeing them progress! (I'm only growing one BR and 3 GG#4's, but the BR is quickly becoming my favorite to watch grow)
Cheers and good luck!
