Why soitainly, nyuk, nyuk, nyuk. :bigjoint:


I appreciate the kudos, and the thanks for my help. I do it because I like to help, and spread the knowledge. But it's nice to get some rep points, too. While I get a lot of thank yous, hardly anyone clicks on my rep. I've always wondered why that was.

Happy growing! :mrgreen:

The leaves are usually the first to show that something is not right, and once they are damaged, they will not recover. They may still do their job, but not as well as could be. The only thing you can do is fix the problem, and let the plant do as best as she can.

the bottom leaves r yellowing and i have no idea wat to do ???
i use around 4 gallon of poland spring water i never used tap water i sterelize my system every week and i have no clue wats making the ph go up

Spring water is not Distilled or RO water
and your pH fluctuation is due to the minerals in the Spring Water.

When I obtained my 2nd tank, it allowed me to do many comparison studies and experiments.
The most impressive experiment was draining one tank empty, waiting ten minutes and replinishing it with the same water and nutes. I always got a growth spurt when i changed the water, I'd get a fantastic growth spurt. After a while, i leanred I didn't have to add NEW water and nutes to get that growth spurt. After many test, I am certain that exposing hydroponic roots to air, allowing them to breath for 5 to 15 minutes really excites them to growth., even when adding back the same water and nutes. I am afraid to go beyond the 15 minutes of dryness.
I saw a remarkable difference when I added a 2nd and then a 3rd airstone is what gave me the idea.

I think you discovered aeroponics.

I turned my DWC into a aero tub
by adding a drain, a rez and a pump.

It's my camera skills and not the roots.
The color is hard to get right in the tub.

When you harvest could ou take some pictures of that top. I'd like to see how you hooked those sprayers on if you don't mind. Did n't mean to jump your thread potroast, just looks different and I'm the curious sort. VV

All right! Hydroponics is what I know, and hydroponics is the way I grow! :bigjoint:

This forum will be great, we can discuss anything hydro. No dirtbags here, We haul water!

We can compare the different nutrient salts, and all of the additives. Plus the kinds of soilless media and what irrigation system is best for each. And of course, pH and TDS measuring equipment, feeding and flushing, etc.

And all the while, we'll make fun of those guys hauling big bags of dirt! :blsmoke:


I can't think of any questions right now, what do YOU want to know?

Hey Potroast......great forum, lots of useful info. Here's my question.
I recently started my first hydro gro. I purchased a General Hydro Waterfarm eight pack, set it up and filled it with plain water. City water is max 200ppm with calcium and magnesium under 34ppm max. The day I filled it the water was 170ppm. As soon as the water reached the fourth bucket in each of the two rows the h2o was over 600ppm. I assume it was from the h20 dripping through the new hydroton rocks. Have you ever run across this problem? Makes it very difficult to adjust nutes, I don't really know what's in the water. Any suggestions?
Gro started out a bit shaky but the ladies seem very happy for 3 weeks.

Did you rinse the hydroton well before use? I've never heard of that large an increase in ppm from only growrocks, but every new system needs some time for break-in. One easy thing about hydro, all you need to do is change the res.

Thanks for the pictures. The close-up shows the first effects of overferting, the slightly brown, curled tips. Young plants don't need as stong a nute mix.

Potroast,
Didn't think of rinsing the rocks, obviously should have. I kept the nutes to about 150ppm over what was already in the water. Should I have run plain water for a couple of days? The plants looked awful immediatley, I thought they were going to die. I think the 1000w MH light might have been a bit too much for new clones also. I went back to fluorescent for a week and a half til they perked up. Now they're growing amazingly fast.
Thanks for the diagnosis.

for anyone wanting to know more about pH and its properties/adjustment, there is a chart called a titration curve. do a search and you will find more than enough info about what pH is, how its measured and how to develop
a titration curve to accurately adjust pH balance to desired levels.

this info will also explain why there is such a drastic change in pH if making adjustments is done incorrectly.

i just got an aerogarden and will try to apply these techniques.

i woould have posted this under the arerogarden thread but its closed.

hope this helps anyone whose interested.:spew:

i just wanted to know if my 1 sq. cubic feet indoor hydro system can handle 3 clones of og. and its like 4 feet tall for growing space. im going to have short ass plants,right

I'm a new grower, using a General Hydroponics AeroFlo system, with coconut pots and clay stones. The plants I have are going into their 8th week of veg., and very healthy. :hump:

I guess my question is this: As the plants go into flowering, producing buds, do the roots need any additional support in the chambers to prevent the plant from tipping over?

Thanks in advance

Dont know much bout hydro but I would have to agree the 1000MH too much for clones, especially if they where just cut, haev to let them relax a bit.
