Jack 47 XL Auto Autoflowering Marijuana Seeds

The autoflowering marijuana seeds Jack 47 XL Auto are the new giant-size version of the already famous Jack 47 Auto. Developed by Sweet Seeds Bank through the genetic selection of large size Jack 47 Auto this third generation autoflowering promises all the flavor and power that made this strain famous but now with even higher productions and XL size.

Jack 47 XL auto is a strain very easy to grow and retains all the vigour and characteristics of its auto-flowering sister. With a height that can reach 130cm, it is a strain that growers must attend constantly and, when grown indoors, must have enough space to develop its full potential. At the end of its flowering present an interesting amount of dense and compact buds, with lots of resin and unique aroma.

The production of Jack 47 XL Auto is very high if we bear in mind that this is an autoflowering that takes just 9 weeks from germination. Indoors, with the help of lights, their yields can reach up to 600 grams per square meter. If it is grown outdoors, in sunlight, production will be around 200 grams per plant.

Jack 47 XL Auto is a powerful strain, probably one of the most powerful autos you can find on the market right now. Its effect is quite intense and balanced and comes with a strong cerebral high to, over time, go down to a very relaxing, almost sedative state.

The aroma and taste of Jack 47 XL Auto is preserved in relation to its normal sized sister. It has interesting citrus, sweet and fruity aromas with notes of incense.
