ph and hydroponics
Hydroponics New ...?
I am new to hydroponics, and I just want to make sure I have all this right before investing time and money into it .... what monitor everything they do when they grow plants? You have a tester of nutrients (PPM) and the use of nutrient solutions to increase, decrease levels of PH You monitor with a different tester and have a separate solution to adjust pH? Not sure what else to monitor? Also, how do you know what plants need PH / PPM levels at which stages of development? Do not buy from Solutions with specific instructions to plants? Thanks
Hi it does monitor the hydroponic nutrient solution, either in parts per million "ppm", or electrical conductivity "EC" hydroponic plants have different pH values "for which there is a table hobby site below me", it is also necessary to control temperature of water solutions as well, you do not want to drop below 21, and there is never any instruction in the hydroponic nutrient solution I-mate fear.
6.8 PH is Good and Hydroponics Makes No Sense?!?!?!
