Yeah, but most of these dumbnuts will spend $250 on an AN or Humboldt rocket fuel or bloom food that's a waste of time and money. What's up with that?
I am a professional grower. As professionals my network of friends use many methods of monitoring their stuff, most of it is high tech. Some of those methods is the chlorophyll meter, leaf petiole analysis (very important), soil moisture monitoring for field transpiration journaling regarding irrigation, etc. The latter uses probes placed at different locations and depths with info sent to a weather station such as the one I have - Davis Instruments Vantage Pro II.
I doubt if any one in this thread even owns a light meter but not to worry! Everyone's a freakin' expert when it comes to light and plant processes.
I have to laugh.....
Still laughing... you are a professional grower of what.. plants; fruits, vegi's, hay, or just bud. My grandma wasn't professional at anything but "maintained" her whole green yard, fruits, trees, shrubs, flowers, and her lawn, anytime the leaves showed deterioration, she removed them. "An ugly leaf is a bad leaf". Her greenhouse had plants 10/12 months a year in Utah. I couldn't name all the plant's outside of her house or in for that matter, when she was alive. Now her being from Holland, flowers and such, and family in horticulture, did not make her professional, but for thirty years of my life, she PRUNED, defoliated, composted the trim, and never let a "bad" leaf stay too long on her plant. All her flowering plants showcased the bloom in question, with any unnecessary leaves removed, for the bloom to fully utilize the daily sun, opening and closing, after the bloom would die, she would cut it away and continue to grow new flowers. Many in her community asked her advice, but she never spouted being professional. DIRT SEED WATER SUN and leave it alone professional; that's your advice.
First of all, You don't need dirt, Reference Egypt, B.C. Due to poor soil conditions, they would grow on decks in the nutrient rich Nile River, Yeah, your kind of boned there as growing hydro in ancient times was never thought to provide higher yields as well as less work to transport water. Assuming you KNOW this, then every post you claim based on soil grow would be false on that fact alone, as science to date has hypothesized, theorized and proven hydro/aero produces better and faster results than soil, based on nominal conditions, which supports this 2000+ year old knowledge. I am no scientist, not a professional, but I prune and maintain yards and gardens with the simple thought " an ugly leaf is a bad leaf". My plants, trees, shrubs, flowers and grass all reward me with lush green vegetation , foliage and flowers, colorful and plentiful.
But being you are always right and your way IS the highway, pull over, you are going to slow, and the OP wants the answer to a simple uncomplicated answer, which through no science save your own experience, which you are hell bound and determined to graft into our heads if not through logical statements, as well as disrespectful rhetoric(some earned) your belief.
The great things about beliefs, is that they are individual, and since you haven't presented a single case study or the equivalent, maybe it is best for this conversation to let it go. As you have already provided your "correct answer for you".
I get that you seem to be intelligent, so am I, I think anyway, But as I said before if it works for you, so be it, I get organics and natural. Not trying to make enemies here, however, much of what I have read from your and others posts shows nothing more than a difference in opinions and technique providing similar results. So in the best interest of sanity and time, I leave the ball in your court brother, This is an actual intelligence test...
