#1318 CBD Harlequin x Black Domina

BlackVeined Sensi Seeds has always been one of my favorite seedbanks. I was very enthusiastic about the recent newsflash from Sensi Research introducing brand new strains on the market with modern genetics. Since I have always been interested in the Black Domina strain, the newly introduced CBD versions sparked utter excitement! I just had to buy both Black Domina CBD strains :). I chose Sensi Research #1318 Harlequin x Black Domina for this grow because of the 1:1 THC/CBD ratio as opposed to #743 2:1 ratio. The final result of this medicinal strain will go up against a future mystery medicinal autoflower strain! In this diary I will grow 2x photoperiod strains. After growing till the 5th to 6th internode I will top off to the 3rd internode and start mainlining. By mainlining I will create 2 main colas per plant (1 cola per square feet). When the 2x tips per plant are approximately 30cm apart I will switch to the new SolarXtreme 250 COB. I will still have to decide how long I will grow till I induce flowering. This is my second grow and on GROWDIARIES! As a cannabis enthousiast I am researching the latest genetics for medicinal purposes in small-scale home growing conditions. I chose photoperiod genetics to compare with my previous autoflower diary with US genetics. These days autoflowers seem more convenient to grow in small spaces and seem to reach the potency of photoperiod strains. I'm eager to test this. Expecting a better resin production on petioles and sugar leaves, we all just love frosty plants! Next diary will most likely include US genetics autoflowers again for a proper comparison. Setup: - Darkstreet DS60 R4 - Mastergrow 600W DUAL LED (100W Power draw) for vegative growth, bloom switched off. - California Lightworks SolarXtreme 250 COB (200W Power draw) for flowering phase.
