Autoflowering variety of high stature.

Tall-stemmed 4th generation auto-flowering strain. This is the resulting hybrid from the cross between 3rd generation auto-flowering lines that were selected for their high stature and a very famous Trainwreck elite clone, used in many medical cannabis dispensaries from the USA. The result is a tall-stemmed strain with a branching structure that is typical of mostly Sativa auto-flowering plants.

On the other hand, this strain features fast flowering, dense buds, high production of trichomes and an intense sweet fruity aroma with citrus tones characteristic of mostly Indica plants. Very well balanced auto-flowering strain, gathering the desired traits of both Indica and Sativa varieties.

It took way too long to get them and then the first two seeds I planted never sprouted. I think I will stick with ILGM from now on!

Could have been better. Got five seeds. One sprouted and flowered nicely in about 4 weeks. The others didn't even crack open. I've been growing for about 10 years so not sure what was the problem.

Big girl. An excellent, easy care plant. She's towering over the other autos, and has numerous bud sites. Very much looking forward to harvest.

AF Sweet Trainwreck. I am growing indoors under 600 watt LEDs. Temps have been running in the 80s so I am adding an AC in that room. Just learning how to manage ph, so this plant was compromised. Only got about 16 inches tall, about a half ounce. Quality is good, high fine.
