Week 17 – Harvest

It has been a very rewarding and refreshing experience for me, as this was the first time I used this type of lights.

I can say that it is a very easy-to-grow strain. The plants developed well despite the low temperatures and low humidity.

For my next run I will improve the net of my ScrOG, making the frames a little smaller.

Regarding the buds, besides being compact, they also have a very good size.

Trichome production was also very good, I just have to say that my grinder gets easily clogged by resin these days.

The final results:

  • Number of plants harvested: 2
  • Taste: Sour, tasty and sweet.
  • Dry weight: 198,45 grams
  • Positive effects: Munchies, relaxed and sleepy
  • Negative effects: Dry mouth
