420DeepGrow Thanks to the team at Sensi Seeds, Xpert Nutrients, and Mars Hydro ā without them, this wouldn't be possible.
ššæ Pineapple Jack:
Feminized photoperiod genetic from Sensi Seeds. A variety that stands out for its tropical and fresh profile, combining pineapple notes with citrus nuances and a very particular herbal character.
Plant with good vigor and structure, with the potential to develop an interesting resin production. Its combination of tropical fruit, citrus, and that Jack touch promises a very attractive aromatic profile during flowering.
š
Week 0:
Starting indoors. Germination on a paper towel with a good success rate, showing a uniform start and stable initial development.
The first days focused on promoting a strong root system and clean growth. Gentle watering with a small dose of Master Root, keeping the substrate aerated and slightly moist.
ā” EC: 0.3
š§ pH: 6.2
š”ļø Water: 21Ā°C
š«ļø Humidity: 70ā80%
š” Intensity: 200ā250 PPFD
š„ Grow note: I was really looking forward to testing this Pineapple Jack from Sensi Seeds. That combination of tropical pineapple and the classic Jack character promises a very interesting aromatic expression. It will be exciting to follow its evolution and see how it develops its structure, resin production, and aromatic profile throughout the cycle.
Let's keep growing strong šŖ!

Mantengo la EC en 1.45 y continĆŗo con Sugar Shot, Silica Force, Enzymes, Sticky Finger y Bloom Booster en dosis bajas, sin introducir cambios en la nutriciĆ³n mientras observo la evoluciĆ³n de las flores.
