The potency of THC comes in numbers. A few crystals here and they may get you nice but you want to clutter the buds with capitate stalked trics - the final mature type of crystal from it's 3 stages. Any light source can achieve a good amount but if you wanna clutter it than you need to drench it with liquid light!!!! The light causes these gals to just resinate my friend, and the more light you have than the more she will eat to rejuvenate what she has used up in her reserves. YES... Nutrients will play a super important role but what are nutrients in excess if you are not making them work out what they have in reserve. Yeah people say HPS produces too much heat... Get over it! Heat in itself also causes a plant to permiate resin from the glands as a surfacant to protect itself from the harsh environment. Look we can grow - whoopdeefriggindoo... But potency is something else. And if you want serious "oh shit I can't walk potency, take a second look at LIGHTING!!!"I was wondering if there is something that I can do or give to my plants that will make them stronger like to have more thc or something like that (I'm not sure that I explained well enough what I mean but I hope you'll understand )
