Well, it has an electric thing that disperses it when timed.. I'm putting that on another timer and was going to vent my tent slightly differently. I figured having this was better than not having it. Also, my mother (oddly enough supports all this) bought me the bucket because I mentioned I wanted to get CO2 in there. I think it's going to be better than nothing, and I FULLY intend on getting a tank and attachment later on. .... plus.. I've already opened it to check it out.. I didn't "start" the bucket yet, but I have everything out because I wanted to check it out.
I'm going to use it either way, and get a tank for the next grow. I know I know... buckets were frowned on, but this one with the electronics on it and being timed and a bit more controlled with hosing going around it from the bucket, seemed better than other co2 bags or other buckets I had seen. It doesn't just sit there, it has a thingie on it that's electronic that I can help regulate it with.
With that said, I'm sure you're smiling right now and nodding your head saying "mmmhmmm, here's another one going off and doing what he shouldn't" and I understand and accept that. hah
I dig ya THG, always looking out for me.
So much help around here, it's just great.
*UPDATE*
I have the holes all done in both the ebb and flo table and the res. When my wife gets home and I don't have to constantly look after my 2 1/2 year old, I'm going to head up into the room and get 'er all setup!
I almost want to germ my seeds, but I wanted to fully wait until the room was ready and I had at least run it for an hour.
