Super easy first grow. Has a nice kushy and sweet smell to it. Had no apparent nutrient issues. The plant stayed really small, probably from my novice attempt at LST and watering issues early on. Still trying to learn how to water autoflowers in a large pot during the first couple weeks.

This is going to be a plant that’s in my garden forever. Looking to reverse and or collect pollen at some point soon. Love the look smell taste and effects of girl crush. A great end of the day strain. Unfortunate about the PM and I am very worried for future grows. But it’s a learning process for sure.

Harvested a small plant approx 1/2 oz. Small due to transplanting and causing the plant to flower early. Next time start in final pot.

Trainwreck (Arcata Cut)
Growing it
Easy
Resistance
Neutral
Had to chop early due to PM but the Trainwreck was much closer to finish than the Old Growth OG. This smells and hits just like the Trainwreck we used to get from Norcal, except indoor instead of outdoor. Both plants were identical and grew happily, though PM did hit all the plants. Trimming resulted in a relatively huge amount of kief dropping into the trim bin. Got about 2 fl ounces of the blondest kief I've ever seen- 3 months later and haven't touched it, because the flower is fucking potent enough. Its sealed in the fridge and should keep for quite awhile.

This plant was a beast, it vegged for so long without any issues at all. Very tolerant to drought. At the very end of flower a deficiency started to show, but don't think it really impacted the grow

A bit light and airy. Not as dense as I would have hoped for but good smoke nonetheless. Fruity with some citrus but not harsh at all. Relaxing high with the clarity and focus of a sativa.

X-Factor (Snow-G Auto F6) is an easy plant to grow. Developed nice golf ball sized flowers. After topping she stunted - zero more vertical growth. However - she grew healthfully though an unintentional bonsai. She dried over 11 days @ ~74°F, 67% RH. (I run higher than 60% RH to compensate for temperatures higher than optimal (60°F). Yielded 40g Dried and Trimmed flower before curing in Grove Bags. Smoke Report in 30 Days AFTER Cure Cycle (4 weeks) Cheers! ~rbw

Biscotti and anything with biscotti is my favorite. This girl was a late bloomer and ended up going almost 12 weeks in flower. She is tasty goodness and a great high. She tastes like spicy lemony limes.

This plan was really easy to grow, it was not picky with nutes and had no issues other than BUDS TOO BIG Had some bud rot due to the closely spaced nodes and huge bud growth. Was able to salvage 3/4 of the plant though Plant smelled so good during grow, really funky. Lots of trichomes

Chopped on day 80 from seed planted in soil until chop. Then dried for 12 days and cured for a few weeks in grove bag. Smoke review: The buds are sticky as hell, which kinda sucks grinding them up. I've yet to press the flower into rosin, but that may be the route to go. I got a combined 7.91 Oz of primo flower buds. When I opened up the grove bag the smell is very pungent. Smells of fermented cherries and gas. The smoke is smooth and not harsh on the lungs. So far, I give it a 9.4/10. I'm sure it will only get better the longer it cures.
