The Best Way to grow Sir Jack Auto by Exotic Seed Bank

Sir Jack Auto Indoors

Indoors, these plants grow big and wide, growing up to 1.2m tall if planted in 11L pots under 18h of light. We recommend placing up to 4 plants, bending the tips a bit on order to control its upward growth in grow tents. A decent grow system can easily give you from 500-550g per square meter using a 600w light; beautiful commercial yields.

Sir Jack Auto Outdoors

Outdoors this large plant is able to grow as much as it wants in as far as height and branches, so it can easily grow up to 1.2m tall with plenty of hefty side branches. You’ll need to give it the right nutrients for it to produce yields of up to 50-100g after about 12 weeks and a thorough curing process.
