Ph

Ok so we need to control our ph in our nutrient solution/ medium for healthy plant growth and good nutrient absorption. Weed likes a slightly acidic medium. For soil plants I keep my ph around 6.2-6.8. For hydroponics I keep a lower ph of 5.5- 6.5.

So how do I figure what my ph is? Its simple, buy a ph meter. Duh. Mine is a cheap digital meter that cost me $75. Mine is for water but they sell them for soil too. They can get expensive into the $300 range. If your tight on cash you can also buy ph drops. Its been a while but I think they are less than $10. So now you got your meter and need to change your ph. I go to the local hydroponic store and buy a bottle of ph up and ph down. Makes things real easy to adjust. You can also use baking soda to go up and vinegar to go down.

I stole this off my ph up bottle.
