In My Opinion Advanced Nutrients Is The Shit! Yeah It Can Get Expensive If You Try To Do The Whole Set Up Of Products They Have But If You Just Use The Basics You Will Get Superb Results As Well. I Am Using Their Sensi Bloom, Big Bud, And Overdrive Andi Noticed A Huge Difference In My Yields From General Hydroponics Products. I Tried Using Their Carbo Load But It Raises The Ph To Crazy Levels In Like Half A Day So I Stopped Using That And Im Not Seeing A Difference From The Harvest That I Used It On Compared To The Last Harvest Which I Didnt Use The Carbo Load At All. So I Think That If You Just Get The Necesseties You Will Have Great Harvests And Save Money Also. Regarding The Post About Posting Pics At 28 Days Of Flowering I Think Thats A Great Idea! When I Get Home I Will Post Some Pics Of My Last Crop At 28 Days To Let People See What I Got Going On!
