Can I mix a reservoir of 10 gallons with Jack’s pre-mixed and then drip feed on a timer for a week or so?
Will it loose potency and can it hurt my plants?
Indoors in a tent.
pH tends to drift upwards so you need to check it about every other day and adjust it.
Potency wont change.
Its actually designed for hydroponics so a reservoir is no problem.
Question in this topic as well. Being that the PH goes up once it sits and I use lemon juice to adjust PH, will adding more lemon juice after it sit throw off acidity. If that’s makes sense and not be good for your plant?
I always use distilled water aerated for 24 hours and mix molasses and jacks and use immediately PH’d to 6.2-6.5
A pH of 7 is neutral. So anything lower is acidic already. I know lemon juice is acidic and works.
The reason pH down in bottle form works is that it is phosphoric acid. Phosphoric acid is a plant food so its safe as well.
I would not let lemon juice and molasses sit around too long. I also do no add either to my autopot reservoir. If I want to add molasses (which I no longer do) I would top feed and mix / add the day used.
I don’t let it sit. I mix after water is aerated and feed to my girls immediately. Was basically just wanting to know if I could save some time but no big deal.
So you think me using lemon juice is a no go? Should I just buy some pH up and pH down?
I would. Its a more stable predictable product.
Plus its just food for the plant.
Okay I’ll get some of that!! Thank you @Spiney_norman
Molassas makes my PH CRASH in a day.
In a week the solution get down to under 5.
Big trouble for my FFOF soil
I agree with others suggesting use of dedicated hydroponic adjusters for ph. If your res is aerated or equivalent you will be fine as long as you keep up with ph.
Okay. I aerate water in a bucket for 24 hours. Add jacks and molasses and water the girls immediately. Growing in coco and perlite.
