Hey Zero,
Yup pet stores and aquarium stores are great places for RO units,pumps and other stuff youll need.Sounds like you are on top of things,if I can Ill give you my two cents on the nutes you are using.Yes I have bought the 4L bottle of Voodoo for almost 200$,etc etc.I think the AN stuff works but is very overpriced but then again maybe you get what you pay for.That being said I also think their charts and suggested use is way way to high.I basically use the root stuff for vegging and cut it out when I move the girls into the flowering room,AN's chart calls for two weeks of the expensive root stuff into flowering.Im sure they know more than I do but I also think its a way to get the average grower to spend more money on their nutes.I go way way on the low end of everything they suggests,and the comment you got earlier in the post about ppm's being a bit high for your little ones is spot on.Its easy to add more if you see they are yellowing out a bit,but if you burn em' or fry em' that is hard to take back and will set you back either weeks or on your yields.Easy does it is a great way to think about it.I take notes on everything I do so that I can look back if I have to and see if I made a bone headed decision in regards to nutes if the plants are in distress. I dont really want to get into a discussion about the merits of certain nutes and companies,I just responded because I have used what you are and was hopeful my post would be helpful.Post some pics of your gals as Id love to follow along and see how everything turns out for you.I am probably a month or so away from making my own bubbler setup so I will be watching,take care,be well,and most all be safe.
