thanks robin... i have had great luck with it... im thinkin adding an additional pump n a big airstone in the bottom will be perfect.... robin in my honest opinion ur better off gettin the 3 dollar bucket from lowes/home depot... grab a 10 inch net pot from worms way and a good air pump and stone... but then again with that u get everything good to go and ready... bucket / dripper / tubing / hydroton / and nutes...... pretty good deal all around... im eventually going to get a splicer and have c02 run into the same tube as the airpump....
