WTF!!!

A couple hundred pounds is cheap for the results you will get. Welding supply companies, ebay, and many more places have them.

a couple of hundred pounds aint cheap at all unless of course your made of money. im sure it would give good great results on a large crop but bare in mind many peeps on here grow for their own use meaning they wont get their money back and also most like myself only grow small crops. if your growing for profit and you are growing a large crop fair enough but you have to take into account that not all of us are here for profit. btw they didnt make that much of a difference when i tried it, well nothing worth jumping up n' down about.

Eh, for a very small PU operation you can rig up a vinegar + baking soda drip... Check the advanced section looking for CO2 related posts.
I like my tank system but admit that for a space much smaller than my 6x6x6 Borg cube it would be overkill.

I hear you with the problem of overwatering, but truth be told, the theory behind NTF is to maintain that nutrient/h2o contact with the roots at all times. Amazing if you have had success with on/off NTF in the past. Ive never heard of that.

I agree with the previous post about O2 vs. CO2. I oxygenate the roots and give the CO2 to the leaves only when the lights are on. As Im sure you know this, you might have gotten a bit high tech for your poor plants. IMHO I would save the "special" CO2 and just put a couple of small sugar/yeast reactors in with the plants during the light cycle. Someone else said it before, but CO2 is one of the last things to worry about. Get a system down pat, then add CO2. Trying to create "the best system" is what we have all tried to do, but doing it step by step proves to be more fruitful in the end. Keep your variables to a minimum and don't buy "special" CO2 when you're stoned

LOL!,well thats one concept man. Hi all,sorry I aint kept you`s up to date,PC probs!

Well... shes not dead, Ive stopped the co2 and the h2o2 and kept a close eye on the PH and shes still showing slight symptoms. Every time I try to up my ppm, it gets worse,then the ensuing 48 hr flush. This is a strain I am really familiar with so its fair to say I know this plant and how it grows and NEVER before have I had a falling PH ? Could this be due to limescale/salt build up in the tank? The tank and tray has a textured surface to it so I can never get it up to shop fresh finsh when I clean it, heres some pics any way. Peace, RM.[attachment=o211437]

Well, in my experience you just get some plants that don't want to cooperate for some reason. This young lady looks like she is not enjoying your 600 watts of light due to the fact that she is not willing to become a voracious consumer of nutrients.

You may be on your own here... I know its not usually a good idea, but you might want to think about cutting back on the light a bit. Sounds to me she just isn't hungry enough and the leaf browning might be due to a bit of burning. Not sure though man, you are getting a better look at her. Going 12/12 and backing that bulb to about 3-4 feet might not hurt. Thats my best guess, sometimes "weeds" need to work for their dinner to become a more aggressive growing plant (ie. letting roots go unwatered for 2 days etc.)

Keep me updated

Im probably just gonna play it by ear,Im pretty sure Im not going too far wrong with what Im doing.... As for reducing the light thats not an option as I dont have another,I can however move it up a couple of feet but even then its only a 2m hight tent so I dont have that much to play with. Also my uncle is having a few similar probs with a tent and a 400wtt(same clone source)Im gonna put this down to a shit clone source (clones were weak and starting to flower)and maybe a furry res lol. Will keep you updated dude. RM.
