Hawiian Snow: Need advice

Anyone have any experience with this strain? Just turned her to flower after nine weeks of veg. She's massive, almost five feet tall, 18 to 30 inches taller than everything else. The base of her stalk is over an inch wide. Topped her at five weeks trying to slow her down. It did for a little while, a couple almost caught up to her. My problem is I think I'm going to run out of headroom. This is my second grow, just wandering how well she'll do going horizontal. My kush did pretty good being tied down on my first grow. I'm pretty sure I'll have to tie her down. I don't want to top her again at this piont, pretty sure that would greatly decrease yeild. I could use some suggestions/tips/ideas/advice from more experienced growers. Thanks to all who reply.

Have you tried Pinching the main stalk? LSTing? HST? Fimming? Supercropping?

Tying her down is a good idea. Also look into Supercropping, and DEFINITELY pinching. People over at IC have trained taller sativas by pinching and LST.

WeayLay is right on target here, slowly training the branching to the horizontal and Supercropping is the best answer. Practice pinching on lower branches first till you have the hang of it and then go after the main colas. This should restrict the highth of the plant and increase the girth of the buds.
