We are happy to announce you from PevGrow, which you already have available on the market, the arrival of the Seed Makers seed bank, a very curious and unique new strain, the result of a genetic fusion between a little more commercial plants and plants that have been true champions, which makes its effects even more attractive and amazing.



Silver Jack, is a feminized strain of Hybrid character with a sativa combination in its 45% and clearly indica in its 55% which makes it oscillate a height inside of 1.8 m and 2.5 m outdoors achieving an excellent production of its buds and very satisfactory effects.



This strain, if well controlled, is capable of fluctuating in only 65 days of flowering 500 g per square meter indoors, with a high quality in its wondrous and strong specimens.

Outdoors nothing is too short, as it is immune to any external threat such as fungi, has an easy care as it can withstand both light from the light bulbs as the sun and in its maximum flowering period, which usually occurs in mid-October, reaches 700 g per plant.


Aroma and Flavor

This weed is made to measure to the delight of your taste buds, since, due to its peculiar genetics, it manages to offer you earthy flavours much in demand by authentic tasters. A taste that will certainly not disappoint you.



The effects caused by this variety are very characteristic of the indica because they work as a relaxing and clears your mind, but Silver Jack, has a feature that distinguishes it from others, will make you laugh like never before due to its smiling effect, perfect for days of slump.



Silver Jack is suitable for all types of crops, both indoor and outdoor.

In indoor cultivation our experts recommend using 11 liters pots, so that it acquires its greatest expression and gives us the largest number of buds possible, with a LEC system due to its gr/w ratio.

In outdoor cultivation, it is advisable to use a quality substrate such as Asturhumus earthworm humus or also worm humus, as well as quality water to provide it with the nutrients it needs. We recommend that you use 18-litre permanent pots, so that you don't see the need to transplant it and stop its growth.


Don't just sit back and enjoy yourself like never before, you won't regret it!
