kudos on how healthy they look top to bottom that's definately not easy to do :thumbsup:

What's the smoke report? after 11 weeks I bet it's gotta be packing a punch even for a sativa was it just the size that took the time or the strand?

The 1000w lumateks are the best as far as I'm concerned even though 600's can get a little closer the drop off in intensity is unacceptable if you were buying new

modest benefits I came by while reading...

240v is better and works out cheaper than 120v and the 1000 240 is more efficient than the 600 240
bulb life and performance(the 1k's have a bigger filament) ages much better
ballast efficiency(1k produces less heat per lumen output)
less reflectors/hangers/venting setups/wiring etc

thanks for all the answers on the last few questions I've had by the way I'm still trying to get everything put together and maybe if I'm lucky it will come out 1/2 as good as yours ;-)
