Grow Diary with Big Devil XL Auto®

Big Devil XL Auto® is an autoflowering strain developed from the cross between our Big Devil #2 Auto® (SWS20) and an autoflowering Jack Herer from the Sweet Seeds® R&D Department.

With this strain we can see an increase in height, thickness and density of the aromatic resin covered flowers in regards to its previous version, producing plants of between 110 and 160 cm in height with numerous and long side branches.

Week 1 – Growing

Grow parameters:

• Light: 24 hours LED (150W)
• Temperature: 28ºC.
• Air humidity: 45%
• Distance from the bulb to the plant: 60 cm.

Nutrients supplied:

• 2 ml/l Voodoo Juice

This is my first time growing with an Autopot watering system. The growing was performed in Canna Coco Pro+ and expanded clay.

Week 2 – Growing

Nutrients supplied:

• Light: 24 hours LED (150W)
• Temperature: 30ºC.
• Air humidity: 40%
• Distance from the bulb to the plant: 60 cm.

• 1 ml/l Cal-Mag
• 0.5ml/l pH Perfect Sensi Coco Grow A
• 1 ml/l pH Perfect Sensi Coco Grow B

The plant shows a very healthy and explosive growing. The roots develop and expand correctly. In a short time frame it will be placed in the AutoPot so that it starts to absorb water and nutrients.

Week 3 – Growing

Nutrients supplied:

• Light: 24 hours LED (150W)
• Temperature: 28ºC.
• Air humidity: 36%
• Distance from the bulb to the plant: 50 cm.

• 2 ml/l Voodoo Juice
• 2 ml/l Sensizym
• 1 ml/l Cal-Mag
• 1 ml/l pH Perfect Sensi Coco Grow A
• 1 ml/l pH Perfect Sensi Coco Grow B

As the roots are already developed enough to be able to use the nutrients present in the AutoPot, it was watered with 10 litres of water with the nutrients mixed in it.

Week 4- Growing

Nutrients supplied:

• Light: 24 hours LED (150W)
• Temperature: 28ºC.

• 1 ml/l Cal-Mag
• 1.5 ml/l pH Perfect Sensi Coco Grow A
• 1.5 ml/l pH Perfect Sensi Coco Grow B

I performed a FIM pruning (high stress technique in which the harvest is increased, increasing the number of main colas in a cannabis plant, which instead of doubling the main cola, FIM pruning can result in more than 4 new colas). On day 24, the plant had grown fast and at full capacity. The daily water intake was approximately 1 to 2 liters.

It is visible at the naked eye how the plant goes from pre-flowering to producing flowers in abundance, with a good stretch and flowering production. La plant has been defoliated, which means that the leaves are eliminated in different stages of the growing stage with the main goal of obtaining higher quality and quantity in the final harvest.

The plant reacted in a perfect way to the LST and to the net that was installed. The bud development is already arriving to its end. It releases citrus and woody aromas.
