PH Question

What is a good PH for soil? I hear some people talking about how PH should be between 5.5 and 6.5, but to me that seems too acidic, and not sure if that is for hydro or soil, if there should be a difference between the two. I have also heard people say that PH should be between 6.5 and 7.

If you are using soil and the ph of the soil is 7 is that bad? I would think that since 7 is totally neutral then there shouldn't be any harm, unless of course the plants are the type that need slightly acidic soil. Not sure if they are or not. Any advice?

the 5.5 is for hydro 6.5 -7 is soil i mix mine at 6.4 or so and my plants stay plenty healthy, hope this helps

by the way weed does like a slightly acidic ph

I use to keep mine at 6.2-6.5. If you were to add nutes to your plant ,which you should,your ph would skyrocket or dive if you didnt balance your ph.

6.0-7.0, preferbly in the middle. I usually ph to between 6.4-6.7.

Cool, thanks for the info

What about different PH's during flower and veg? say, 6.3-6.5 during veg and 5.5-5.8 during flower?

I havent heard of this. you're saying that you should change your ph for flowering?

I have a friend who does this... thats what I was asking. anybody know why?

you guys may be refering to riddleme's make it rain technique. He has 2-3 tutorial threads on it and other things, I do not adjust my ph like he does but i do follow the heavy waterings and well aerated soil like he does, it seems odd but the pots actually dry out alot quicker if you do it this way.
