It's my first post and it looks like there's some sort of "permalink" set up for my question. As for tieing it down, I'm growing in a Phototron 6 (first time in one) so Im sort of tight on the sides also. I'm very very surprised at the results I'm getting! I've grown under a 400W HPS before but I'm getting what looks to be better results out of this Phototron thing. And I thought it was a rip off joke...I guess you can't believe everything you read on the net. It could also be the seeds too though but so far so good.:thumbsup:
