Only new to the hydro scene our tap water here is 0600 ppm. If my seedlings need to have a ppm of 100 - 250 What then should my ppm meter read? Might be a silly question but I want to get this right.:joint: I will be using a flow through system with rockwool as the medium.

600 ppm's should be well water and not good well water at that. tap water should be 100-400 ppm's good well 400-500 and 500-100 should be checked cheched by a pro to see why it's so messed up. my well runs 180-270 ppm's

I would think so. if you let it sit some might settle but the pump would mix it for sure.

Does that mean I would need to buy bottled water because that PPM in tap water is standard in the area PS. Just goes to show the shit they put in scheme water

hope you don't drink that crap. Need some info from a real hydro guy. the soilds in the water are salts and other crap my ppm's run 850-900 at full nute mix but it's over 1000 when I add the molasses. also not hydro just soilless

Haven't started yet just want to get it right. Seedlings are germinating from today. Do you think at quarter strength our PPM meter should then read 850 that seems far to high.

I'm not sure about the ppms. As I understand it. the salt build up takes a little time and will start to block nute uptake in the plants. I flush once in veg with low or 0 ppm water. flush is 3to1 and then again at the end of flower to get rid of all the nutes. Where do you run your ph at? I also added some lime to the coco blend

thx stumps i run my ph at 5.5 - 6.0 and i use canadian xpress nutes for coco and some additives to help with enlargeing the nuggs i havnt flushed mine for ages or the last 2 cycles,only because the plants look so healthy with no side effects.but ealry on in my growing experience i had trouble getting a plant to 8 weeks and looking healthy it was on the way out at 8 weeks ,but after fine tuneing and good nutes they look like they could do 2-3 more weeks.

take a look tell me what you think.
