PH is the most important thing in growing hydroponically.
A too high or low PH will quickly show up in plants, sometimes being fatal. Even fluctuations in ph will stress plants, it is important to keep it constant. If you have to adjust your water to use, then do so in a seperate container.
the second most important thing is nutes or ppm. plant s don't use all the nutes in the res., just what they need at that time. as the res lowers it can be topped off once with your ph adjusted water, then check the ppm's and raise as needed. when it needs water again clean the tank out along with the pump, reassemble, refill, test and you're good to go.

heartsurgerysurviver Reviewed by heartsurgerysurviver on . Question about REZ level and NUTE concentration i was wondering this, my 5 gallon REZ level lowers naturally due to evaporation, uptake in plants or whatever the reasons. so when the water level lowers like this, does the concentration of NUTES increase? or is there actually less NUTES because the plants have eaten them up? so is the water evaporation/plant uptake in proportion to the NUTES being used up? okay, this question is getting to weird sounding... basically, if the water goes down in level, what do i do? i know i'm getting an Rating: 5
