Im expirementing right now with a four plant sog type grow in dwc. I havent changed the res ever. Six weeks. Im going to check the ph because i havent changed that either, they are doing fine. I started them at 250 ppm and didnt really raise it untill they started drinking water noticeably. Ppm is at around 500 now. Hold on ill go check ppm and ph and snap a pic for you.
image.jpgimage.jpgimage.jpgI think the ph shows around 6.8 maybe lower. Never been phd or changed in .....37 days. The ones in front are trainwreck, in back are shishkaberry. Ive growen them both before and they are doing exactly what thier much larger sisters are doing on a smaller scale. Sensi a and b, pre ph perfect + calmag and superthrive. Thats it.

So WTF lol I have to add ph down on a daily basis and lots lol. When I do a res change which is every 7-8 days I have to add 100 ml per 100 L just to get it to below 7 and then its a real bitch to keep it there. Thats been my biggest issue to date! I would love to get RO but its complicated lol. No plumbimg in the shed! Like I even went as far to start using sulphiuric acid to be able to up the concentration I throw in. I also use Sensi ph and it will feed plants anywere between 5.5 & 8 I believe without lockout. But never had slime lol just something else to look forward to huh lol. Actually I'm on my way out to throw some acid in now as I pull on the rubber gloves lol.

Dont quote me on this but i think i remember somewhere reading that RO water is harder to keep ph in check with. Im not using the ph perfect sensi, i use the pre ph perfect. I dunno man, all i add is nutes the cal and the thrive and its ph is six everytime! And it seems to stay there. I dont know but you saw the pic above, shes holdin steady at 39 days lmao!:)
