not exactly.. leafs on a cannabis plant are meant to be grown in natural position (not inverted) if you look at a pot leaf you will see that the bottom of the leaf is different than the fop of the leaf the top is greener and contains more chlorophyll than the bottom.. tomatoes kinda grow like a vine and leafs are odd shaped and grow to face the light even when the plant is upside down when cannabis grows upward and erect.. ive come to the conclusion that it would be best to just rig a reflector to light the bottom of the cannopy if thats what you are goin for.. its cool lookin i guess.. i wont waste my time this year i think ill use the turvy for some real tomatoes or maybe safer with peppers as they dont get as heavy
