Week 21. Harvest

Happy Harvest Day!
Rated
10/10
Rated
Girl Scout Cookies from Barney’s Farm proved to be a strong, resilient, and very grower-friendly strain. She handled mainlining exceptionally well. Every cut, every tie-down, and every stage of shaping was met with quick recovery and vigorous new growth. The plant kept a solid structure and responded exactly the way you want during a mainline build. One of the biggest positives was her robustness in tougher conditions. Temperatures in my setup reached up to 28°C, but she never showed signs of heat stress. Leaves stayed healthy, growth remained consistent, and overall she behaved like a plant that can take a beating and still thrive. Her structure was compact with tight internodes, making the mainline very clean and symmetrical. The aroma came on early: earthy, with that signature cookie dough and minty undertone that Girl Scout Cookies is known for. Buds finished dense, resinous, and visually impressive. Overall, Girl Scout Cookies by Barney’s Farm is an excellent strain for growers who enjoy training-heavy techniques like mainlining. She’s sturdy, heat-tolerant, and rewards the effort with top-quality, frosty flowers. Perfect for both hobby growers and more experienced cultivators looking for a reliable performer.

xTaps This week the plant received her final watering with Bio Boost, just enough to let her finish strong. After checking the trichomes carefully, most of them were milky, exactly the stage I prefer for the effect. With the maturity right where I wanted it, it was time to harvest. The plant was cut and trimmed, and is now placed in the DryFerm bag for a slow and controlled drying process. Everything went smoothly, and I’m really happy with how the grow ended. Now it’s all about patience while the buds dry.
