Growing w/o meters?

I have 2, 5 ga. bubs.
can i grow without EC/PPM meters?
I will use ph testers tho.
thanks.

I did two succesful grows with pH test strips and no ppm meter. I still don't let my ppm meter boss me around and tell me what to do and when. Just follow the instructions on the nutrients.
You do have to have a proper pH.
Look at my Tutorial here:

Roseman's DIY Bubbleponics-DWC Tutorial

There would be a lot of $60 accessories I would give up before my ppm meter.

I have found that as long as your able to check your ph, and read the directions on the back of your nutes, then yes you can grow decently with out it. Check my grow for proof if you want hehe.

PH is much more important. I don't George Washington had a PPM meter.
