Need help with ppm

Cropster · May 23, 2009

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.

is that stright from the tap it reads 600.mine does to.
if you let it sit for a day check it again tomorow it should be clear.all the shit they put in the water.

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

once I turn the pump back on it will mix it up again and bring the PPM back up to 600.

I'm no expert just read what it said on the meter.

stumps · May 23, 2009

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

Cropster · May 23, 2009

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

sorry guys i get my water from a treament plant and with all the chlorine and god knows what else they put in it takes a day to clear all the shit away.

how big are your plants are you feeding already i have used it straight from tap before with no side affects

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

hey stumps do you grow in coco?

and may i ask a ? on your ppms u run and i see alot on riu are quite low to what i run mine at i grow in coco and are at like double those ppms u r running with no adverse affects. :peace:

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.
