Rox Flower Enhacer PGR's

Hey guys, Just a quick question on Plant growth regulators, if one was attempting a Single Cola SOG seed plant that is designed for max yeild when would the best time be to use rox i know on the bottle it says after 21 days but has anyone personaly used this product and if so how is best to achive top yeilds, the outcome of this plant is not to be sold or smoked it will be binned as it is purely as a bet to see max yeild on a cola the test can only be on 1 plant due to it being diffent strain to the normal plants in the grow room and only 1 attempt can be made (rules of bet)


Please do not post about Rox,SuperBud,FlowerDragon or any other pgr products being bad for your health , like i have previously said the final product is to be binned after weighing,


Thanks

Anyone out there ?

idk what tht product is

Thanks anyway
