TtHE EXPEREMENT

[dontknownuttin]

DAY 37 WEEK 6! Outside temp. today is 112 todays grow room temp. now 72 above RH now at 25%. All newts at 100% CalMag at 5ml per gal. 100% RO water grow. Leaf curl must be due to light and not heat lights on 24/7

🌱 Despite the heat they look like the buds are developing well! 🌱

As many may know, I was buying MANY bottles of Distilled water for my DWC at my local store each bottle cost me .95 this really adds up to the grow cost weed is a thirsty plant!!!. I got a 5 stage RO filter and a TDS meter I have been using it for all DWC watering needs.
My first water bill came today it went UP by a whopping $3.00!. My cost per gal. for DWC water, is now 4.1 cents a gal. The RO filter in itself will save about $120.00 a grow!. The filter provides me many gallons (they claim 500 gal.) of low 0-5 TDS water for a low price. (note) I also saved $62.13 on electricity by using the reduced wattage 400 Watt 10K MH finishing bulb during vegetation instead of a 7K normal vegetation 600 Watt one . All together I figure I shaved about $200. on grow costs. My goal is to reduce grow cost to about what a garage freezer cost to run but maintain a respected harvest, or balance between cost and pay out .

DKN, how much did the 5 stage RO filter cost? Do you have it in the kitchen? How do you fill your reservoir?

[dontknownuttin]

Now, if only we could talk Fox Farm into charging less then $1.00 a tablespoon for nutrients!

The R.O. filter is a ON DEMAND table top model (I keep it in a bag under my desk in the dark between uses) Initial cost of filter from Amazon was $119.00 (shipping included). Filter replacement cartridge kits are available for $75.00 This unit says it will filter 500 gal. between cartridge change out. I guess it would also depend also on how hard the initial water is you are filtering. The water I filter has a initial TDS of 172. After filtering I get a TDS reading of (2) I check every R.O, gallon I make with a TDS meter before use. My house water is hard at 172 but not bad enough to tax this filter it seems. I store the RO water in gallon jugs for DWC use. I keep 5 gallons plain on the ready for PHing and future use.

Thanks DKN. Very helpful information.

[Aloner]

I'm guessing it's this one, is that right?

[alltatup]

Aloner Thanks!!!

Sounds like the Stage 5 is an awesome addition to your grow, DKN.

Some day I may knowsumttin!

PERHAPS that day is today!!!!!

So it leaves 7% of the total cyanide in my water????? just kidding... but still...

[dontknownuttin]

starting with TDS rich water is like painting a picture on a smeared canvas, the cleaner the canvas the better for optimizing mineral availability

[Tazard]

House And Garden recommends that you stabilize RO water to 180ppm, how do you do this? My tap water is about 180ppm at 7.5pH but I have seen it at 8.9 pH.

[Tazard]

Beautiful ladies you have!!!

Day 46! Hot outside today 113! At canopy level the temp. is 71 degrees Temp. at roots is 65 degrees RH high today at 35%

[dontknownuttin]

I wonder why they call this plant the "Auto pounder?

[alltatup]

Don't you mean Quarter pounder?

[dontknownuttin]

At this moment it is a no pounder

[alltatup]

Let me ponder the no pounder. Do you think your root temp. might be a bit low? I have read that too cool temps on roots can stunt growth. Nebula says:
"Many growers aim for their reservoir water to be between 60-68°F because cooler reservoir temps prevent some bad organisms from growing in the first place, and cool water can hold more dissolved oxygen in the 60-70°F range. However, cannabis can grow and thrive in much warmer reservoir temperatures as long as beneficial organisms are present to fight root rot. In fact, I personally have found that hydroponic plants tend to grow a little slower when their roots are cool, and grow fastest around 75°F (as long as you're using a supplement with beneficial organisms to kill root rot).

Of course, at that temperature you don't have to worry about root rot at all.

The experiment was a success SO FAR. Week 7 in a few days.

[dontknownuttin]

DAY 54!!!! I figure about 6 more weeks! I still wonder why they call this plant the AUTO POUNDER?

[alltatup]

Wait about 35 more days and you'll know why!

Lookin good, DKN!!!

[dontknownuttin]

Height: 60cm-100cm
Harvest: 70-80 days from seed
Stone: Deep body stone
THC: Medium/High

[alltatup]

DKN, why do you figure that you have 6 more weeks? If you're at day 56, you shouldn't have more than 3 weeks to go to get to day 77.
