ph question :)

[Django_TO]

The only reason DI water is anything but neutral is the variance in processing or re-absorbtion of environmental impurities or minerals. True DI will have no minerals or impurities a meter needs to give a ph reading. As an above poster mentioned, if DI isn't close to neutral, it ain't true DI.
That being said, I'm a biobizz light mix user and only use DI for 2-3 weeks with no adjustment.. I've used several different brands of DI but never noted any deviance from batch to batch that ever caused a problem. AAMOF, DI water is my controlled source when ph is suspect.

Hi. Can you tell me when/how you use distiled water? You start with it and use it for the first 3 weeks? And then you start "regular" watering with nutes? My first grow i always used tap water (rested for 24h and with ph corrected or ph perfect nutes), so i'm wondering if DI would be better for the new grow.
Thanks

Use PH up to get in the range that BioBizz recommends. I would recommend getting a Boogie Blue water filter instead of buying the gallons of distilled. They make a small size that filters 10,000 gallons and another that filters 45,000. https://www.boogiebrew.net/water-filter/ Great filter and wont have the waste water that an RO system creates, RO systems can waste 2-4 gallons per gallon produced.

thanks for the nice and simple answer i have been looking for hahaha i thought that i would need ph up and i will check wat ph bio bizz reccomends also. thank you this is my first grow so ill stick to the di water then maybe get a water filter in the future

Sure...glad to share my simple usage info. I am lucky to live over the largest aquafer in the USA and my water is from a private well in a large farming community.....but I buy DI just for seedlings. Germing in vented solo cups and transplanting into small 2 ltr pots of biobizz light mix makes it easy to know when to water. Been doing it for years but still double check with a cheapo moisture meter.
When I start with nutes, I switch to my own ph'ed well water. Ya just never know what municipalities add to what they wanna sell ya.
All I'm actually doing is eliminating any potential incorrect ph adjustment/ and or seasonal water table changes.
The variance in DI is much less than variance of tap water.

some tap water is to high ppm/ec to use. for me really as a beginner trying to learn like my water is very hard water and has a high ppm of like almost 2000 thats no good for seedlings and such a pain to use and figure out the amount of nuits i can use so iam planning just going with di as it has very low ppm /ec if not 0 ppm so its a good base for beginners id say well i think thats right from what i have researched hehehe

so you saying distilled should be 7ph basically ?if its not its not actually distilled ?

Exactly.
The pH scale is defined as pure water having pH exactly 7.
If some claimed distilled is far from 7, then it's not pure, and the distillation process was probably flawed.
Impurities must be present to change pH away from 7 if a batch of water isn't exactly 7.

ok i guess ill get to testing some water brands hahaha i never knew ph was to do with purity of the water i thought it was just a scale used to read nuitrent uptakes for various plants learn something new everyday

My Distilled Water tests at 7.8 PH. I don't use it for growing just my humidifier. No matter the source of your water you should PH test it so you know.

 

[LordRandall420]

6.5-6.0 for seedlings 6.3-5.8 for veg 6.0-5.5 for flower in the PH. This is for COCO coir.

im not using coco and im just going to try go with a straight as begginer ph maybe will vary between 6.0-6.5 throughout

hey guys just brought some distilled water its ph eventually balances out to around 7.4 i was thinking i needed ph up but it seems it need ph down
and my tds meter reads about 160
