If growers here had their harvest tested by a lab for THC content, I bet 75% would find that their weed has about half the THC content of dispensary grown weed. Dispensaries where I live have their donations tested by a lab near me ($75 a sample) and post such results when you go to order from them. Most DIY'ers can grow the most delicious looking jewel encrusted dense nugs and have the THC content not be that high. I know from experience having grown great looking spears only to have them not get me ripped. They got me stoned, but not ripped like dispensary weed which tests at 18-24 % THC. I haven't had my grow tested, but with how much it doesn't get me ripped, I'm guessing the THC content to be in the 9-13% range. Am I hoping to reach the level of pro grow farms in potency? You bet. First off is to try something other than my BestVA 1000w $109 LED panel .Maybe one Horticulture 135w 3000k Quantum lighting for a one plant stealth grow (around $200).
