Your pictures show that for a new cannabis cultivator, your results will be far above average. Improvements? of course, that's the joy of gardening. Always another oppertunity to improve and have that 'perfect' (LOL) grow. You are, IMHO, asking all the right question and planning well ahead. Keep it up and in no time you'll have members asking you for your secrets to success.Hmm, what kind of medium are you using? And what kind of light? Something tells me you're doing something VERY correct in regards to your terpenes.
I myself am not running the most spohisticated ops currently. I don't even know if the seeds I purchased will produce the top quality bud. HOWEVER, to give myself some credit, I'm not growing any of that funky weird froot loops looking bud that tastes like carnivalcandy, I am growing kush plants. Supposedly high in THC. Who knows.
...and I'm just curious, your user name, are you from or in the Valley of the Sun. We lived there for 40 years. (and don't answer if you don't want to, that's personal)
