Fhydro, I got those skunk specials doing great, 1st week flower. Thanks for your post. Female Seeds .nl thanks you too.

This is my 3rd grow and I think I finally have the perfect "cocktail" of hydro nutes because my pH is the most stable I've seen. I do have a slow rise like I am supposed to. THis is a good thing because that way I know the plant is using the nutrients. I don't know how much C02 effects the pH though unless it is injected (like Zandor said) into the resevoir.

One thing to think about..... I think pH up bottles and pH down bottles lose their strength and stability after a while. I had a problem with a weird drop in pH (from 5.8 to 4.5 in 12 hours). I have never seen or heard of this. It's always been a fast rise in pH and not a fall. I couldn't figure out what the hell it was so I asked around the message board. Zandor suggested I use new fresh pH up. I threw out the last bit of older stuff I had and tried new. I brought the pH back up to 5.2-5.5 and there it stayed. So....if you have old pH adjusting liquids, I would buy new ones.


what nutes are you using? Tell me exactly what kind of water you use, supplements, everything. I'll see if theres something I can do for you. If you want my recipe, I will gladly tell.
Stormcooker Reviewed by Stormcooker on . PH stabilization in bubblers system Yes, it's very hard to stab the PH in bubblers system or in any system where water is aerated by air stones. I notice that i start a rez with PH 6 and the day after it's 7 so i've got to lower it, and under some particular conditions, the PH is 4!!! Now i've got the exponation from an aquarium seller. When there is few CO2 in the air, there is more oxygen, the PH goes up. When there is a lot of CO2 in the air, less oxygen, the PH goes down. When i saw py PH to 4, i had added CO2 the day before Rating: 5
