Thank you so much for doing this, just prior to catching this thread and making my first post on this forum I was on the fence and now a couple weeks into dyna gro, protek and recently picked up some cal/mag, still cutting my teeth and learning so much and with this being second grow outdoors I am already expecting dramatic results this time around. I constructed darkening area last week due to I have a street light/HOA which did not give me main colas last year and have been doing quite a bit of undercleaning to put more energy into tops this year. Last year did not top, this year did, many changes this year and this thread helped me immensely, thank you so much HB for your work, I am a couple months out being outdoor so I will have to be patient to see how much all of my changes made but they would been much more confusing if not for re-reading the entire thread. I hope you continue to post and share what I believe to be honest, unbiased, very thorough information.
