i grow a nirvana new purple power indoors and im pretty sure it was an outdoor. but it grew really tall about 5-6' and just wouldnt stop. seemed like no matter how close the light was it would stretch. i dont thikn it really stopped till like the 7th week of flowering. got a total dry weight of like 200 grams dry weight. but it started out on a 60 watt houselight, to a 150 watt MH to a 300 watt HPS. stalk got no thicker than a sharpie marker but that was my fault. :/

it was just me and my setup.. but im gunna say flower pretty early and they will triple their height no prob. (again i dont know if this applies to all strains and whether it was indoor/outdoor)
iamhigh Reviewed by iamhigh on . Growing Outdoor Strains Indoors In general, what should be done differently to grow outdoor strains indoors in a small space, say 4' wide x 3' deep x 5' tall? I'm nearing the end of my first moderately successful closet grow with one known indoor strain (supposedly Northern Lights). The other, unknown. Meanwhile, I had Holland's Hope seeds delivered by mistake. Instead of raising a fuss, I figure I'd try to grow them at some point. Thanks for any insight or personal experiences growing...or using...Hollands Hope, Rating: 5
