    yea i was looking at a rapitest meter its 4 in1 ph,light,moisture, and fertility, i was wondering if this is any good? would the fertility be accurate? what is the best way to know how much ferts ur soil has in it? that goes for before u plant and after u plant? thanks for any help...:smoking:

    Fertility?? What physical property would that actually be measuring?

    i think it combines the n,p,k in the soil? but that doesn't seem very accurate to me, how would u know how much of each was in it?

    I used one a few grows ago, it was junk, never did read real accurate and then the fert meter always read low, one day just for kicks I mixed my nutes triple strength and it read just ok for the level of fert, if I would of put the ferts on the plant I would of fried them. But hey it could have just been a bad meter.
