you really need a hybrid, with your setup ... I'm also a 'sativa guy' ... my cabinet is 7.5 feet tall, and growing out my Willie Nelson sativas was a pain in the ass ... too tall, 14-15 weeks flowering, etc., it just isn't worth it ... do your sativas outdoors ... indoors, there are hybrids around that stay 4-5 feet tall, provide good yields, and have predominantly 'sativa-effects' ... do some strain reviews, find one that describes what you're looking for ... I have recommendations, but I'm sure folks are tired of me haranguing the same old names ... but, 100% sativas, in my opinion, belong outdoors where they can become TREES :thumbsup: ... :jointsmile:
