In case you have build up a THC tolerance, Excalibur by Eva Seeds is the sword that will cut right through it. Being forged from Amnesia and Diesel, both high quality and brain-thirsty metals with medals, it represents a true stroke of genius in blacksmithing with a very strong and intensively energetic impact on the clear head and a relaxing effect in the afterglow. Excalibur grows multiple blades with a large main handle and several secondary knobs. All it takes her is one strike and your train of thought is beheaded and yet you will happily anticipate the next swing.

Excalibur is hungry all the time, so feed her well during both the growth and flowering period (but dont forget the flushing before the harvest). She is highly adaptable and retains her sharp blade in soils, coco and hydro set-ups.

In an indoor plantation it is recommended to switch the photo-period as soon as the plants have reached a height of 25-50cm. Excalibur does not stretch much during the flowering period, when the harvesting time has come after 60-65 days, she ist only 80-100cm tall. But she is a great yielder, depending on cultivation method and allotted space you can expect anything from 55 to 80g per plant (at 9 plants per square meter).

Grown outdoors, you should consider sowing as soon as March through to June. And before you decide to grow her in a guerrilla operation, you better rethink your decision as she easily reaches a height of 180cm and has the potential to scratch at the 3 meter mark! Those trees are accordingly productive and can yield anything from 500 to 1,000 grams each. The buds are ready for harvesting in early/mid October.

The huge and densely packed buds are interspersed with orange-brown pistils and exude a delicious aroma of mixed fruit salad seasoned with citrus juice. Excalibur is an excellent choice if you are out for making hash - the abundance of resin is an invitation to do so. The flavor of the end product is very pleasant, it is fresh and lingering on the tongue and palate.
