It really depends, there's too many variables. In general I'd say it is going to tend to gradually get more acidic over time if you didn't lime it and especially if you use high-N fertilizer. However, one of the main factors here is actually your water source. If you use hard tap water it is most probably alkaline. In this case the soil pH could stay steady or gradually increase. Again it depends what if anything else goes in the water or the soil, aside from what the water is like in the 1st place.

I'd give you a more technical explanation, but for some reason I doubt it would help.

The amount of time a plant is grown indoors isn't nearly enough time to bring a well balanced soil to an undesirable pH state. Start with a well buffered soil with lime and don't worry about the pH of your soil, or your runoff or any of that shit. Unless your feeding it some ungodly amount of nutrients then don't worry about your soil pH anymore. Good Luck

Yea, I check the run off my ff soil when I first water the soil and it stays stable most of the grow. Run off is usually 6.2 every time I check a new bag of ffof...

As a general rule of "thumb", when I used FF soils (especially OF). I would add a handful (about 1/2 cup) of Ag lime to a whole bag (1.5cf) to cover late pH fluctuations.

I used to see those with synthetic use.......That is directly connected with what Nullis said!

Doc

When ive used ffof my ph would always go low. A couple of times very low. Once my runoff had gotten as low as 4.0. To solve this problem i started using 1 to 2 tbls per gallon of dolomite lime and never had a problem since. Now i grow organic using subs super soil. Now i dont ph anything. Water going in, runoff nothing and haven't had a ph problem. Ever.

I agree, every few weeks I sprinkle a little more lime over the top of the pot and water in. The odd occasion I check run off it always seems to stay pretty stable, so I've just left it alone now.

Any buddy gots Sphell Chex ? .. Jus axin

more important is to understand about the ec level in the soil and as the soil drys out the ec level increases

so if you been feeding your plant high strength nutes and you let the soil dry out too much you can kill the plants
