Exotic Seeds Sir Jack Description

Exotic Seed Sir Jack Definitely one of the clones we like to work with and grow the most, selected around the year 2000, now presented in its "S1" version, crossed with itself so that you can enjoy this selection as much as we do; originally from Sensi Seeds Jack Herer. Sir Jack is a robust plant, which helps keep the weight of its large flowers. With an elevated level of resin, it is highly recommended for performing extractions, producing a super high quality "Ice-O-Lator". With Sir Jack we recommend monitoring the humidity of the room, since the density of its flowers, with a high relative humidity, can potentially cause Botrytis to appear. But if there is something worth highlighting about Sir Jack is its taste and effect, which has granted it multiple awards throughout its career, with a clearly marked incense and lemon flavour, which lingers on the palate, being a difficult taste to forget, like its effect, strongly brainy, which leads to a more Indica-type body feeling, without being disabling. This strain is not recommended for novice smokers.

Yield m²: 550-600 g
Percentage Indica/Sativa: 30%-70%

Richfield - 10.07.2017

This comment is connected to a Sir Jack review!


Die Sir Jack wuchs (innen) ausgesprochen stark sativa lastig

(schlank, nach oben gedrungen, mit großen und dünnen Blättern).

Die luftigen Blüten waren überdurchschnittlich mit Harz

überzogen. Die Sorte wuchs in der vegetativen Phase enorm schnell.

Sowohl in die Höhe als auch in die Breite. Der Ertrag war für eine

Sativa enorm hoch. Die Sorte reagierte sehr gut aufs Toppen und

bildete an ihren langen Seitentrieben sehr große Blüten aus.

Das Verhältnis zwischen Blüten und Blatt-Masse war unglaublich hoch.

Daher konnte man die Sorte sehr schnell und effizient ernten.

Die Sorte benötigte mindestens 9-10 Wochen um ernte reif zu sein.

Daher kann ich mir nicht vorstellen, dass man die Sorte

draußen in Deutschland anbauen kann. Ich kann mir aber gut vorstellen,

dass die Sorte sich draußen zu einer Monsterpflanze entwickeln kann,

wenn man die Sorte in der entsprechenden Klimazone kultiviert.


Die getrockneten Blüten haben leicht würzig und scharf gerochen.

Vom Geruch her insgesamt sehr außergewöhnlich !!


Insgesamt war die Wirkung der Sorte rein Sativa lastig. Vom High

und der Blütenstruktur her hat mich der Effekt ganz stark an

reine Landrassen Sativas erinnert. Die Wirkung der Sorte war geistig

stark anregend und zu gleichen teilen auch leicht entspannend.

Während des Rausches war man sehr motiviert aber nicht körperlich

energetisch geladen oder überdreht. Dabei war man zusätzlich

leicht angeregt und gut gelaunt. Die Sorte hat ebenfalls sehr

gedanklich angeregt. Insgesamt war die Wirkung jedoch nicht

überfordernd, wie bei starken psychedelischen Sativas.

Nach dem Rausch war man dann relativ wieder klar im Kopf.

Die Wirkungsdauer lag bei ca 2-3 Stunden.

Von der Wirkung her war die Sorte definitiv eine der besten

und vor allem angenehmsten Sorten die ich rauchen durfte.

Gerade das weiblich Geschlecht ist total auf die Sorte abgefahren.


Die Sir Jack war eine schnell wüchsige Sativa Sorte mit einem enorm hohen

Ertrag. Der Effekt, (ein motivierendes und anregendes aber jedoch klares Sativa High)

war leicht überdurchschnittlich stark. Eine klare Empfehlung für alle reinen Sativa

Liebhaber, die ein motivierendes und leicht entspannendes High haben wollen ;) this comment
