Papa_T
started grow question 5y ago
I’m just curious as to what PPMs people’s tap water comes out at. I’m currently at 58 PPM but I’ve seen 71 at the most. What’s you?

90 ppm, you're going to need a calmag supplement till you reach 256 tds ppm wich is 0,4 ms/cm some products have calcium and nitrogen in them so check the % of calcium or mg in to adjust the amount of calmag.

My well water is about 170 ppm, mostly with calcium and magnesium. It has a pH of about 7.6 but both number vary season to season and year to year.

Rainwater pH?
Should I worry about rainwater throwing off the pH of my soil? The water that I give them is always pH'd to 6.3. Will the pH of the rainwater inhibit my plant's ability to take in nutrients. Rainwater is slightly Acidic from what I've read.

Storing compost tea?
Any ideas for storing compost tea? Plants on differing watering schedules due to taking in water at different rates. Started a tea today to help correct some issues but 2 of 3 plants won't need water for another 12-36 hours from time it's finished.

Buongiorno a tutta la community, volevo chiedere ai growers più esperti, quante volte può essere clonata una pianta partendo già da una talea? Mi spiego meglio, si può creare una talea da un clone di una pianta madre? E quante volte si può ripetere questa procedura?
