Description
G13 is a long-flowering hybrid that rewards growers for their patience with large, aromatic flowers. Highly recommended for experienced growers – you will need to have a lot of patience with this strain in order to grow it right. It comes from a combination between an original G13 strain and one of the best Mr. Nice’s Haze.
Indoors this strain does perfectly well under SCRoG systems, using a trellis net and placing 4 flowerpots per light. This will allow you to create a trellis of balanced, quality buds that take 9-11 weeks to finish flowering after flipping the lights. If you want you can place 9 to 25 plants per light and grow them using a SoG system. Its long flowering period makes up for the wait by producing amazing results – up to 500 g per square meter when grown in professional conditions. Check out Square Flower Pots In All Sizes to see which ones adapt better to your needs.
Outdoors this strain can get enormously big – due to the fact that it takes a while to finish flowering, we recommend planting it in a greenhouse unless you live in an extremely dry climate when it comes to November and December. This strain can produce two phenotypes; one that’s bushy and another that produces plenty of branches in all directions. Both phenotypes grow to around 3 m tall and generate up to 750 g each when grown under good conditions and given the right care.
Its intense, incensed aroma is quite Haze, as well as its flavor, with a sort of fruity hint. Its high is quite strong and mental; it’s perfect for relaxing or having a laugh with some friends.
Highly recommended for expert growers only.

Incredible for outdoors. The plants get huge, I had to put stakes everywhere, otherwise it's a disaster. The yield is really good and the smell... pff, a treat. It takes time, but it's worth every single second of waiting.

Incroyable pour l'extérieur. Les plantes deviennent énormes, j'ai dû mettre des tuteurs partout sinon c'est la cata. La production est vraiment bonne et l'odeur... pff, un régal. Ça prend du temps, mais ça vaut chaque seconde d'attente.

How much can the stem hold with those giant buds they talk about? I'm worried it might snap.
Translated from Spanish
¿Cuánto aguanta el tallo de los cogollos gigantes que dicen? Temo que se parta.
