Because Amnesia Bilbo can grow to a towering height, it is not the best strain for stealth growing. But if you have no choice but to rear it outdoors, there are ways to limit its vertical expansion. Left to its own devices, it can easily develop into a small tree of around 2 to 3 meters (6.5 to 10 feet). Therefore, it must be trained early by either topping or fimming it. Not only will these techniques produce a shorter, bushier plant, but they will also encourage more bud sites to emerge.
Unfortunately, that is not the only concern when growing this strain in the open air. It can be very fussy about the climate, preferring tropical or subtropical conditions with lots of sunshine. It could also attract pests and bugs because of its enticing aroma, so you should consider protecting it with a natural pesticide like neem oil or insecticidal soaps. Give it the extra love and attention it deserves, and your plant will gift you with 1500 to 2000 grams (53 to 70 ounces) of delicious, sticky buds around the end of October.
If the maintenance and preventive measures sound daunting, you should take your operation indoors. A grow room or tent will allow you to regulate all the environmental conditions better. Especially during the 10 to 11-week flowering phase, the temperature should be kept within the 21 to 28-degrees Celsius range (70 to 82 degrees Fahrenheit). Concurrently, you should maintain the RH (relative humidity) level at 40 to 50%.
Inside, the maximum height of the plant will be about 190 cm (6 feet). That would not be a problem if your room has a high ceiling; if it does not, you should employ a combination of low-stress training (LST) and the Screen of Green (ScroG) method. If all goes well, you can expect a bumper yield of 650 to 700 grams (23 to 25 ounces) per square meter of grow space.
Feminized Amnesia Bilbo seeds produce an all-female crop because they do not carry the male genes. Without any male plants, the females’ blooms will not be pollinated, thus ensuring a bountiful harvest of smokable buds. Taking care of this strain requires experienced hands, but if you are a gardening neophyte, you will be glad to know that it has another version that is easier to grow.
