Description

Jack Ultra CBD with 600w Grow Light
Indoors, these plants produce plenty of resin and aromas from the second week onwards, and it begins preparing its branches to hold up its hefty buds. It should be able to hold them up easily although a bit of training wouldn’t go amiss if you’re looking to increase bud weight. You can harvest a decent 600g from around 10 plants per square meter when using a Lumatek 600w Dimmer Kit.
Jack Ultra CBD Grown Outdoors
Outdoors it’ll grow much larger than indoors because it’ll have much more space to grow out its branches and the central calyx into a sort of chandelier structure. Its leaves turn a dark green color outdoors, and with the right temperatures the buds can grow a sort of grey color. You can help it flower by adding extra sugars and fatteners, which results in incredibly thick and juicy buds. One plant in a 20l flowerpot can produce up to 600g.

This strain is awesome. The perfect balance, you know? It doesn't knock you out, but it's not just a placebo either. For aches or after work, an absolute blessing! Anyone else use it for that, with effects similar to rica CBD?
Translated from Spanish
Esta genética es una pasada. El equilibrio perfecto, ¿sabes? Ni te deja K.O. ni es solo placebo. Para dolores o después de currar, ¡una bendición! ¿Alguno más la usa para eso, con efectos parecidos a la rica CBD?

Great for relaxing, without that annoying paranoia. The grow was super smooth, yielded well and the plants seem very resistant. Better than many I've tried! The effects are smooth and pleasant.
