3rd generation autoflowering strain. Tall-stemmed version of one of our most appreciated autoflowering strains: Green Poison Auto®.

Green Poison XL Auto® was developed within a recurrent selection programme of tall-stemmed Green Poison Auto® specimens across multiple generations. These seeds produce plants that height around 25% more than their ancestors, with a higher flower and resin production.

The tastes and aromas of this strain are very pleasant and intense, with sweet and fruity tones, a sweet Skunk background and hints that are reminiscent of rucola and walnuts.

Would be buying more. This is a nice auto! Popped 2 of the 5 I received and got 100% germ. We had 2 completely different phenos in size but both put off nice yields in a timely manner. Definitely not as fast as they say it is but worth the grow!

Grew this with little effort! Turned out really nice. Will definitely be ordering more Sweet seeds from Seedsman. Shout out to Laura in customer service. She took care of a problem with a quick response.

Plant grew nice and short (which is nice with my 3' tent), looked really healthy up until the flowering stage, when the fan leaves started to turn yellow (I think this was my fault - I didn't start giving nutrients until week 5). However, buds looked good and large throughout entire grow, and without any training my one plant yielded 30.0gs, with two other plants (different strains) in my 2x2x3 tent. Very impressive, resilient, plant, smokes somewhat harsh but certainly does the trick!
