Cheap PH down?
smokeyspartacus
started grow question 5y ago
Is it just me or is GHE/AT PH Down very diluted? I started with gGrowth Technology which is 81%. TA PH down has nothing stated on the bottle... What do you use as the cheapest way to get PH down in circulating hydroponics/DWC?

Not sure if it works with hydro/DWC but citric acid is a cheap pH down. It’s water soluble so I’d imagine it be ok. Worked great for my organic grows.

DIY fertilizer - Beet and sugar beet.
Beet molasses, has anyone had experience with that beside Biobizz products ? I was thinking to make an experiment with beet, but I can't find the sugar one at my country, so would any other strain be good for that? Any comment about diy fertilizer is welcome !!

Watering in Super CoCo
Hey there fellow growers! So I’ve been trying to figure out the best watering schedule and volume 🧐I’ve been told to always water with runoff, go by weight, top inch dry, etc. I guess my main question is runoff necessary when watering in Super CoCo? All advice appreciated!🌱

BioThrive Fertilizer Water pH & PPM
I tested my BioThrive Bloom+CaMg fert water for the first time ever today; I've been feeding 4.5 pH & 340 ppm fert water solution; Soil pH is 6.7-ish per the Rapitest meter. Should I add pH up solution to make the fert water 6.2pH? What if the soil pH increases over 6.7?

Wie kann ich die ppm des Wasser auf eine kostensparende Art senken? Mein Leitungswasser kommt mit 375 ppm aus dem Wasserhahn, was für mich ein viel zu hoher Wert ist. Wahrscheinlich handelt es sich dabei um viel Kalk im Wasser

Feeding advice.
What should I feed? I'm 2 weeks into my second attempt at a first grow lol. I'm growing an Auto in soil, outdoors in the UK. I'm trying to keep things organic. I've researched rabbit manure which I have and liquid seaweed. When can I use these? Do I need them?
