True, and lights are even MORE important to growers who self-impose limitations on the other essentials. For example, my water is just water, so I have to be sure my soil has all the calcium, magnesium, nitrogen, and so on. Worm castings, luckily, takes care of that! I just grow slower, and produce less buds, but I guarantee you they are top freakin shelf :) Stay tuned fam.
But yeah as time and budget allow I will also be upgrading my light situation, and LED is something I'm looking at, cuz of my small garden size.
And yeah, airflow is another part of the equation so a better fan at some point will help too. Thanks for the info.
