whats a good brand/model?

Thanks for any help...ROOR
 
theres lots of home made stuf that can lower ur ph but it can cause a series of other problems. i would suggest dolomite limeu can pick some up at the hardware store
 
lime is a "buffer", it works at keeping a neutral PH (7.0) and won't bring it any lower. "Horticultural" lime should be added and mixed in "well" before any plants are planted for it to be effective.
I would suggest lowering your nutrient water to around 6.2-6.5 before feeding. "PH" down...from the hydro store.
 
Interesting thread, because like the poster of another thread, I too bought a cheapo Rapitest PH meter, and have become increasingly aware of the crucial need for a PPM and EC tester, as well.

I expect to hear that the Rapitest tester is not sufficiently accurate for the task at hand, but in keeping with part of ROOR's question, what tester (within reason $$$...let's say $75 or less) do the more experienced growers in this forum use, and recommend?

This one looks to be a good tester, but I'm not sure I like the lack of a digital readout, and it only goes up to about 3550ppm. http://www.marijuanapassion.com/forum/newreply.php?do=newreply&noquote=1&p=48588

Regarding that link in my above post...ummm, that's what I get for lighting up a bowl during the day! :D

Actually, now that I think about it, that's an interesting thought. How about a poll... "How many of you are totally stoned while you're reading and responding to posts?" Pass that doobie, Dude! LOL

Anyway, here's the proper link to that combo PPM/PH/EC meter I was looking at: http://www.nutra-wand.co.uk/

Almost everyone is using em most likely... I don't notice any difference between them.. i got one off ebay w/ calibration solution n the works for like $40 after shipping. Works fine for me.
 
hanna is a good name brand, i use the ph level drops which isn't the greatest method, but the cheapest...
