Dbyrd Posted October 11, 2010 Report Share Posted October 11, 2010 Here it is http://www.amazon.com/gp/product/B000RUI9QK/ref=pd_lpo_k2_dp_sr_3?pf_rd_p=486539851&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B0000DI845&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=0X1W98HP299623T1QNGR I am wondering what should the nutrient numbers read for soil?

THC-Farmer Posted October 12, 2010 Report Share Posted October 12, 2010 The very first thing you should do is purchase some pH 7.0 calibration solution and test the pH readout on it. Those types of meters are never accurate at all. I've tried the RapiTest versions and can honestly say they are absolute garbage. I bought one just to test it out. I have pH 4.0 calibration solution and pH 7.0 calibration solution. Upon testing it in both solutions the readings were WAY off. In the 4.0 solution the meter was reading 6.9. In the 7.0 solution the meter was reading somewhere around 9. I would be just as skeptical about this one as well. You get what you pay for in this situation. I do not recommend either the RapiTest pH meter nor the LusterLeaf. Both are incredibly inaccurate and unreliable. Milwaukee makes an excellent pH pen for a cheap alternative. http://cgi.ebay.com/...=item1e5e59ff4d <<-- $30.98 w/free shipping. The pH600 is the exact meter that I use and have been using for about 2 years now. It is still very accurate. It needs to be calibrated about once or twice a week. But I check it before I use it every time. It's a champ. Still reads 7.0 like it was brand-new... I highly recommend this product. Quote Link to comment Share on other sites More sharing options...
Highlander Posted November 1, 2010 Report Share Posted November 1, 2010 THC Farmer is right. Cheap meters are useless at best and are about as bad as just guesswork. Quote Link to comment Share on other sites More sharing options...

Dbyrd Posted November 15, 2010 Author Report Share Posted November 15, 2010 Only thing I even use it for is the moisture meter and the light meter. Other than that yes it is crap. I use a liquid PH tester at the moment. Quote Link to comment Share on other sites More sharing options...
