Heruk - Hydroguard is the Botanicare product I add to my nutrients to guard against root rot and other root problems. Liquid Karma is a vitamin, amino acid, compost, and kelp extract product that promotes vigorous growth.
Myrelic - My CO2 setup is really quite simple and I'm assuming it's working well, although I really don't have anything to compare it to. It consists of 3 one gallon milk jugs that contain pure water, bakers yeast, and sugar. The jugs are filled about 2/3 full with warm (not hot) water, one packet (1 tsp) of bakers yeast, and 2 cups of sugar. I also poke a small hole in the lid for the exhaust of the CO2, which is one of the byproducts of the fermentation process as the yeast eats the sugar. The mixture is then shaken up and within about one hour, carbonation bubbles are noticeable. I also place a balloon over each lid and poke 3 pinholes in each balloon. This way I know when the concoction needs refreshing when the balloon is deflated. To refresh, I pour out about 1/3 of the water and put fresh water and 1 cup of sugar back in.
The 3 jugs were started 2 days apart and numbered 1 - 3. This way there is a cycle of fresh mixtures every 2 days. All jugs are placed into a cardboard box that has an outside air intake consisting of about a dozen small holes near the top, and a 4" air duct line attached at the bottom (CO2 is heavier than regular air, hence the reason for the top/bottom setup). The duct line runs into the grow box and has an small computer case fan to assist drawing the air in from the CO2 box. THERE IS A PIC OF THIS SETUP EARLIER IN THIS THREAD.
That's probably a little more detail than you needed and you probably have already read about the yeast mixture elsewhere, but what the hell. It might help some other people that want to know about the mixture. I can smell the fermentation and yeast inside the grow box, so I assume it's increasing the CO2 level to some extent. I don't have a CO2 gauge, so I'm not sure what level it's reaching.
