I have one of those pH testers for fish tank where you take 5mL of water and drop 2 drips into it and shake and compare to chart but i have feeling this is very inaccurate so im looking forward to my pen!

how big are the containers you use?
I think the 16oz cups are fine.....i just ran clones in 32 oz gatorade bottles(cut down to about 24 oz and only filled with about 20oz of medium) with a one week veg...and by the end they were no where close 2 being rootbound.....I use the same kind of ph tester with the drops.....seems accurate enough for me.....i bought mine at wal mart for $5(i am investing in a pen soon, but the drops have got me by for a year now!).......and the containers i use are around 3 1/2 liters recycled coffee tins. Thanks for stopping by and feel free to ask as many questions as you would like! :thumbsup:
