When I initially mix my res, for now. I have been adding shock/uc roots first. I will have a cc/fc of around 3 ppm or so, but as soon as I add nutes the strips read 0 for both. Its just interesting. I am starting to think the biggest benefit of using sprayers is not so much the D.O. but the lack...

I am using pool shock/uc roots too but I noticed that once you add nutes the chlorine readings go to zero. Still seems to work though.

Do you ever measure your free and total chlorine?

Agree and disagree. If you need to ask something like "how to build an rdwc" and people have to tell you how to screw a fucking fitting into a bulkhead, hell no. Someone with basic plumbing skills and some knowledge of chemistry, sure. That person has a fighting chance of taking it to harvest...

My first grow ever of ANY PLANT was a homemade RDWC. It was a smashing success. I could not have asked for more. I think hydro for a beginner is good in the sense that if you fuck something up, you know it the next morning and you can relate that problem to an input. In soil, it seems like your...

That's a good idea using coolers for a dwc.

They seem to have survived the transplant well enough. I guess just patience for now. I am running about 100ppm of just GH three part. That's about 1/2ml of each part to 1 gal for me. When the sucker leaves yellow I will bump it to 250 the next week and 300 the next. My last grow topped at about...

Not at all man. I will tell ya what I know. My next setup will be a two-tote with a 20-gal can as a res.

I have a chiller. I think the problem is whatever is in my tap water. Pool shock is working great and keeping my PH much more stable than I am used to. Still working on installing a permanent RO that my wife can also use for drinking water. 2ppm FAC seems to not be a problem for the plants. I...

1. Bleach the shit out of the system. 3/4 cup bleach per 1 gal and ran it for awhile. 2. Obtain a starter tray/dome and some 1.5" rockwool cubes. Learn the proper way to handle rockwool. 3. Figure out how to run a sterile res. I bought some pool shock and at 1g/gal makes a stock solution of...

EPIC FAIL So, its been almost a month..... Long story short......Since my last grow was so successful I feel I did not learn some important things. This can be evidenced by the complete and total failure of my grow this year in several aspects. 1. Bennies worked well for me last year, but not...

No, that math is right btw. 1g into a gallon of RO@ 58% Cal-Hypo seems to make a 150-200ppm stock solution for me. Clear Res and UC Roots are both around .028 (or so) of HClO which is around 280ppms. I found this stuff called Pure and Clean HClO. Double strength as compared UC and Clear Rez...

Those banjo ones are some of best you will find. The rubber washer is nearly twice or three times the size (thick) of other brands of bulkheads and a much better rubber. Not to mention the material of the fitting itself.

Don't you have to add nearly twice as much since the HTH is only 62% CalHypo??

Thanks! Yeah I figured as much about the PPMs but did not know if that applied to PH. Now, if it evaporated that much to cause a PH drop the EC would have went up as well? Mine did not, thus ruling that theory out.

Once I soaked the seed, I covered the hole with a corner I had cut from the rooter. Each of the 3 JH's sprouted this big fuzzy-looking root and did much better than my first run. They all pretty much look the same now. See how I crossed out Headband on the lid and wrote Jack Herrer hahaha. It...

So yeah. I tried 4 headband seeds and three of them died but not from damping off or something like that. I figured out I was a fool and did not cover the hole in the rooter enough so that the root did not get exposed to light, wind, ect. My RH is very low, like around 30%. One survived, and I...

That 315 cmh is perfect for your 3x3 space, I LOVE mine. Enjoy those frosty buds!

By environmental control, are you saying you had it hooked to a heat exchanger of some kind to cool your space? It seems like that would be much more efficient than running a/c, no?

Thanks!
