In the bottle it does smell a little like Worcestershire sauce or steak sauce, but when you spray it on the plants, it smells like ass. Not sure what is in the stuff, but the plants love it. I have use daily it in the past, but this is the first time I am using it with the tabs. The entire system, as we have all discussed, with just a few additions early on and the Silicium Flash, and you are good to go for the entire grow, start to finish with no issues at all.
That is the goal...find an easy system that works for you.
I am also in the camp of not wanting the biggest yield, just the best quality, cleanest smoke I can grow. BioTabs is the answer for me.
