once you've add ya nutes to the res check the ph and if needed add ph up or down as required,then ilet it run for 30 mins and check again..
i check once a day until i kno where its going to be roughly but i still check daily ya pH will probably drift after a day or 2..start at 5.8 and don't go over 6.2..
gluck some 1 else will be along soon hopefully they will chime in..
mickrick Reviewed by mickrick on . pH when to check? Hello! I am growing hydroponically in a 5 gallon bucket with a rockwool cube. Also using Fox Farm Hydroponic nutes. I have a hannah ph/ec reader. My question is when do I check the ph? I change the solution once a week. Do I check it right after changing the solution? Do I wait a day? I'm barely getting my calibration stuff this week so I'll FINALLY get to start using my meter! I just wanna make sure I do it correct the first time.:thumbsup: Rating: 5
