Hydro Questions: Help!!!

[MaryjaneMenehune]

Alright, I was hoping to learn about co2 production...for now, ill just show you some experiments I have been able to make to feed the little girls.
Photos:
first is of all three different methods, one being yeast in sugar water that has a tube that goes into saltwater so the bacteria dies and the room remains sterile, second being a milk jug filled with baking soda used as a basin whose lid is glued to a water bottle which contains vinegar (there is hole drilled through the lids that are glued together)...the water bottle has a tiny hole at the bottom of it, so when flipped upside down, flow stays constant and the vinegar can funnel it's way down to the baking soda which reacts to produce co2 which is piped next to the plants.......long explanation. and lastly there is the last which has more detailed pics, you can figure it out, same baking soda and vinegar reaction...

2nd shot of holes for co2 to travel through in pot.
3rd is of same bottle from second method (upside down) filled w/ vinegar
4th is of whole contraption in full functioning mode...
lets in light.....
co2 supply......
paper filter to allow air transfer(good or bad?)......
notice how it is propped up so it is as close as possible to light (used cigarette box for props).........(you can tell if you look real close in last pic...lol)
i think thats everything.
peace

Forgot to ask, should I be giving the plants supplements like that in such high concentrations or is it better to give them a little all day long...if so, how would i do that ? (preferably low budget, but if you can increase results dramatically for on an advanced set-up, let me know about it...scuba tanks are off limits)

Mary, very inexpensive and free fertilizer is urine. dilute 1:10 or more. 1 part urine:10 parts water. If you have nothing else. It worked for thousands of years before we had monsanto making our fertilizer.

I added a tiny bit of urine to my molasses and shultz plantfood mix and despite what people say about going low budget on hydro, i am pretty impressed at how this little guy has bounced back...
oh yeah, one more thing...would the co2 produced from the baking soda.vinegar want to rise or sink in the air? i have been using warm vinegar in case it likes to sink, but it is an exothermic reaction, is it not? i am pretty clueless....

look at high times /ask ED pro that give you any info you need

One good and easy source for Co2 i've found is dry ice with some water to cover it. The plants seem to be doing fine, but some are a little yellow on the newly forming leaves. Is this normal? Should I start with ferts even when they are only two weeks old?
Finally, should the leaves that were apparently overwatered start to spring back up or will they stay pointed down kind of?
The hydro plant seems to be doing fine, but i have yet to order any nutrients... planning on gh 3part, superthrive, liquid karma for now...
Is ebay safe to buy from, i've heard a lot about them selling their suspicious buyers list to the dea?

imp: heres' how...Answer to your first question...1)The marijuana plant is very hardy meaning, it can withstand temps as low as 40 deg. before it has major effects on growth (slowing) it depends alot on variety of plant. (which you failed to mention) Or the plant can withstand temps. as high as 120 deg. (don't recommend) The ideal temps. uaually fall in the range of 60-85 degrees the more light available, the ideal temp. for normal output increases. Night temps should be about 10-15 deg. lower than in day. In plain english,80 deg. daytime 65 deg. nighttime.2) MOLASSES????? Try cow manure,chicken manure,blood meal,dried blood,worm castings,Guano (bat shit), cottonseed meal,greensand,feathers(breaks down slowly),hair (breaks down slowly) OR 3) try mdhydropnics.com or hydroponicsonline.com. I really hope this helps. Need more info? respond.imp:

Mary, I read an entire thread written by a guy on overgrow that used urine for his grow. That's all he used for the veg cycle. For the flower cycle he used urine and bloom nutes for extra safety. He only used the urine water every other time he watered. He was using a drip system with rockwool. It turns out the rock wool was acting like a pond filter and beneficial bacteria could live in there and protect the roots from the buildup of bad bacteria. So to make a long story short, dilute urine will work for dirt. Since the dirt acts as a filter. This will only work for hydro if you use lava rocks. Some said hydroton would work and others said there wasn't enough surface area. I've tried this using lava rocks in a swc container. It does work.

1) How long would a quart each of the 3part nutrients last me in a 18 gallon resovoir(dwc)?
2) And how frequently do you need to change out the water to prevent buildup?
3) I was thinking about putting some lava rocks into the tank to help filter out the bad bacteria; how effective would that be and is it worth it?
4)besides the gh flora series, i was looking to get liquid karma, megagro, and also some superthrive... sound complete enough or should i be looking at any other products? (ill think about bloom bud and big bud when the time comes, for now, they are babies)
5)can any of the previously mentioned nutrients be used for soil grows with any success?

Question 1. Depends how often you change your nutes.
Question 2. This varies depending upon the individual. I've heard as often as every week to never. Watch your plants. They will tell you when something is wrong.
Question 3. I have lava rocks in my swallow water culture. It can't hurt and yes if you are using urine, you must have this as the beneficial bacteria can live in lava rocks. They can live in anything porous, scrubbie, etc.
Question 4. I don't know, never used any other products except superthrive and I'm not sure about it.
Question 5. I'm sure you could use those nutes for soil, but why would you? There are much cheaper products out there for soil grows.

Remember opinions are cheap. Best advice comes with experience. Try it.
