Instead of arbitrarily flushing my pots every so often I was thinking of getting something to simply test the excess water. Also I am curious about what's going on in there as in addition such information would be useful in telling me when it is time to change media instead of guessing and just arbitrarily doing it by a "rule of thumb".
I am thinking all i would need would be a tds and ph meter....after looking into it a little I do have 1 question in regards to the equipment.....obviously u get what u pay for but also there is no need to pay for all the bells and whistles one does not need.
I think one can get separate "value meters" for around $15 for each of them or pay 3x of the combined cost and get the combination meter for around $90. What advantages does that fancy *** meter have over the separate meters? Or am i just paying for a bunch of functions I do not need?
Is there an alternative i do not know about? perhaps a "value" combination meter i can find for about $40-$50?

Uhh, no! Take it from me who has gone through this! Here are several meters I would recommend:
1) American Marine Inc Pinpoint fluid conductivity meter. I went through three meters before this one proved extremely reliable for testing the mS of the water.
2) Hanna Soil Test - EC and Temperature. I have personally experimented with the levels of the mS of the water after flushing soil. The EC of water and Soil are quite different so if you think the EC of the water IS the EC of the soil, then I am afraid you are mistaken. This soil probe will help.
3) Blue Lab Soil PH kit. (Can't leave home without it!) I have found that by adding ONLY 3 drops, yes, 3 DROPS of General Hydroponics pH Down concentrate liquid acid, it drops an entire gallon of water to about 4.5 Ph and an mS of about 18. So start with pure rain water or store bought deionized. Otherwise your mS will start to sky rocket and potentially be problematic for your plants.
Yes, these are all quite expensive, however, you most definitely get what you pay for regarding the measuring instruments for horticulture. We just need to find a right balance to all factors. These three, though seem expensive, are the best I have found with all things taken into account and they are the ones I personally use.

plantguyty1: Does anybody need pollen? I have N. Miranda it's the first time it flowered for me so I do not know if its sterile or a good candidate. Is there anybody with an active female that would like to give my pollen a shot?

borneo: Yes, they work superbly. But you don't need expensive lights, cheap ones work well too.
