With a 250 I don't think that's enough light. However if you have a sealed room with no vents you need it to keep up the level of co2 just for growing. If you can vent the room it's better.

With co2 you need alot of light and bring the temps up into the low 90's. And keep the water cool. That's the problem, keeping the water cool.

Another thing is co2 can displace the air and flood a room or house making it imposible to breath for animals and people. So be very careful if used in a people living area. It's odorless and tasteless so you don't know it there.

Oh yea you got enough light to grow you a good crop. It's just to use the co2 to help get a harvest a week early you need more light and hotter conditions. It only gets you a week off harvest. Not really a bigg deal or worth it to most of us. So just a little would help but not make a lot of difference. A couple little fans moving air and breathing on them alot helps just as much.

My roots are deep in Scotland, hope to visit some day.

Excellent, got a good fan on now...and don't have to sweat it with the co2 lark. And on the other subject of roots were abouts in scotland do you know?, I've a son in Arkansas... yeah had to spread my seed across the pond lol stayed in the states for 7 month back in 2002..4 months over my welcome time....it was all that mexican food couldnt get enough of it....back to growing...keeping the nute res cold will be no probs..i'll have to stop it from freezing lol...cheer again bro and will keep you up to date..
