pH Levels

[floridadread90]

What is the recommended pH level of my water used for watering my plants.

[Thothamon]

The same as the PH of the soil, which CAN be anywhere twix 5.5 - 7.0
There are so many 'depends on..' though, like soil type,nuts type,strain type yadda yada

6.5 to 6.7 if all other info is unknown.

[floridadread90]

appreciate it.

[Dr. Bloor]

Measure your ph in and then your ph out. Mine without nutes is ph 7, neutral. Ph out is sometimes 5.7. With nutes my water in around 6.7 to 6.5. A lot of differences. I think these girls can take it. I think if you are ph 7 or lower going in you are ok. Are you in soil. I am.

A chart for your reference. Shows both hydro and soil.

Not good info.
6.5 - 6.8 is the range for cannabis to grow happily in in soil.
Strain type and soil type are not important; while different strains do appreciate different nute levels, pH is fixed, and any deviations need to fall within this range.

[Dr. Bloor]

Thanks Stinky for that! I have a lower ph happening here out of my soils. I go in with a watering of ph 7 to 6.8 and run off with 5.7 or so.
So I need to adjust to a water runoff of ph6.5 to 6.8?

[Thothamon]

soil wasn't mentioned in the first note, so ya. 6.5 to 6.7 is what I said. *boggle*

weed does just fine down to 5.5 in hydro but that pushing.
Sorry but the info is NOT wrong.

[Dr. Bloor]

I am using a commercial soil with a ph of 5.5 to 6.5 . 3 different ferts on 6 different plants,I should really be checking the ph run off on all these plants. I only did several of them. The other clones I have are all getting Fox Farms Bloom Booster. Is that any good?
Stinkyattic : Should I adjust my water ph to alkaline ? How much? Thanks

Stinkyattic: Should that be water out or in? Sorry same question.

You SPECIFICALLY said soil in the first quote... it's still there if you care to look back.



Have you ACTUALLY grown anything outside this holy 6.5 6.8.?
Yes, I have. When I was playing around with using peat in my mix. And guess what? It died!



What we would really like to speak to, is YOU telling a first time INDOOR grower to use cowcrap in the mix they use.
Ya, noobs don't have enough to lose sleep over what with lighting, heat,ferts,watering,smell... lets raise the chance of them having a BUG problem along the way by about 60%!
Top 5 worst noob advice ever. EVER!

Any packaged product that has been processed for sale should be free of pests and weed seeds. Would I go down to the local farm and get a pile of shit for my indoor garden? Of course not! I recommend a SPECIFIC brand and source that I have EXTENSIVE personal experience using INDOORS without introducing either weeds or insects.
I stand by my advice to use that composted manure and humus product from the farmer supply.



Man, this whole place 'feels' like its Stinkys way or no way.
Heh, the old man thinks you work for leo, tryin to screwup noobs so they giveup LOL.

That's right, my goal here is to make everyones' crops fail.
And I'm a cop... :wtf:

I'm sorry you feel like that.

I'm leaving this thread open and up for the time being; can everyone please just chill out. I'm not taking much offense at this quite honestly, I'm just a bit disappointed.

[Dr. Bloor]

I find it to be an interesting topic. Something I am interested in. Sorry about that guy SA!

[stinkyattic]

Oh no worries.
As a matter of fact, I didn't actually ban the guy... another mod did.
One thing I will say on the record is that me being a mod isn't something I'd ever want to use just to get the upper hand in an argument over grow styles/information- I'll sit here and argue with anyone, lol; as long as everyone is polite about it it's good, and everyone can learn from both sides.

Now back to your other question of the water in vs water out thing.
It's something you need to get a feel for.
Say your tap water is 7.
Your runoff from an initial flush is 6.5.
You can then assume that the true pH of your soil is actually a bit LOWER than 6.5, and you will want to bump it up a bit.

When you have such a large discrepancy between where you WANT your soil to be and where it actually is, it will likely take a few tries to get it stabilized at the proper level. So after the flush/adjustment, let the plant chill for a while, let the soil dry out a little, and next time it needs watering, check once more and adjust again if you need to.

Fixing the pH of bad soil is as much an art as it is a science, lol. That's why I like my humus! Buffer = 6.8-6.9.

[Dr. Bloor]

Yes lets all stay polite and try to turn learn something! Well back to the topic I guess I may need to bump my ph in up a bit. Last runoff I collected and checked in clean containers was 5.7 with a ph of 6.8 going in. I will check some plants again tomorrow. Thanks.
This girl looks happy, but I think could be happier!

[stinkyattic]

That's a gorgeous bud, well frosted!

[Dr. Bloor]

Thanks. The plant has three like that on it. I was looking at them today with a microscope and they are getting real cloudy. I was thinking of taking these buds off and letting the rest of the buds go. The whole plant is covered in the same type of bud but, smaller. It is right on the greenhouse roof!

[Dr. Bloor]

Juicy Fruit and a clone. Smaller buds of the plant I think I will take the buds off of.

[Dr. Bloor]

I do need to ad some ph up on some of my applications. I noticed a plant that looked a little peaked, yellowish leaves I gave her a T of fish emulsion. Ph7 on water and then with fish emulsion added it was 5.7. The plant is close to harvest.

[Orzy]

damn, those buds are frosted. Nice work, :thumbsup:.

[evertking]

The use of dolomite lime and some humic acids in your soil will help you keep a stable PH.
Just some thing to think about next time.
Good luck!
