normally i wouldnt worry to much about a follow up to something like a reservoir change... but i was stoked after this one and thought i would share...
since the beginning of the switch to the hydro system i have been plagued with stupid issues... heat, PH, res temps.. it took almost 2 weeks of work but i finally got it all taken care of.. and it finally payed off.. finally i got some good news about everything..
first off i managed to get it done in under 2 hours... so it was less time than it took last change.. plus i was able to get all the pumps and the aerator cleaned out along with a full cleaning of the reservoir itself... due to the layout its near impossible for me to move it somewhere to clean out.. but i figured out a way to get it done without moving it today.. so that alone was set my mood off right..
secondly was the temp.. once i got all the nutes in, which i do while it is filling so they can mix, i plugged in all the pumps and the chiller again.. i cant run the chiller without water running through it or it will burn out.. the chiller pump helps to keep the nute solution mixed as well as the aerator so both are nice to have in the reservoir.. but im getting off topic... so the chiller has a thermostat on it that displays the current temp and set temp... well after i filled it up and plugged it in the current temp, which was the water temp of what i used to fill it, happened to be the set temp.. not really anything special.. just was cool it happened to be the exact degree as the temp i set the chiller to.. makes it nice that it wont have to lower the entire reservoirs temp, which means it wont have to run for a while..
third was the ph... quick note.. i am in the habit of calibrating my ph meter every res change.. since it stays in there i worry about the salts messing with it.. and since ph means everything in hydro its just a good habit to have.. the ph meter was spot on which is reassuring to see.. and after all the nutes had cirrculated well and i checked the res PH it was 6.0.. spot on where i wanted it.. i added a little ph down just to help it maintain the low 6's throughout the day until tomorrow.. ill see how much it goes up over night, which it will do... i havent figured out why it does it so much... or if its even normal to do that.. but i got plenty of ph down to take care of it.. i wonder if there are any affects of the ph down to the plants in large doses?? anyways.. i didnt have fuck to much with the ph which was nice...
and lastly was the EC/PPM... it was damn near spot on to what i wanted... 1.8/2.0 EC and 1000/1100 (x500) PPM...
it was seriously a perfect res change for me.. or what i would envision as a perfect res change... hopefully the few girls i got left at the moment enjoy it... they are looking good.. ill post a few new pics in a day or two.. and ill find some to stick in the pic for comparison so you can see the amount of growth easier...
ph.. i am in the habit of calibrating my ph meter every res change since it stays in the res.. i worry about it fluctuating, and since ph is very important its just habit now..
