why would one dump and refill weekly? this is nothin but a waste of money don't need to dump reservoir but one time at harvest thanks though, mister know it all for you 2 cents
ouch, lol. Once the plant has some size, and you start a week, with fresh water/nutes at 1800 EC, by the end of the week, it will be under 1000. so you have to add more. You mean you just dump fresh nutes in once in a while without changing the water? just want to make sure I understand you right.
no plant ever needs 1800ppm, first of all secondly, if your nutrient strength is dropping that much, it's because the balance is off and needs adjusting my nutrient strength very rarely moves in between topoffs so yes, when needed, i mix a gallon of nutes, ph to my desired number and add to the res
\t \t \t \tEC, not PPM PPM is a mathematical deduction based off it's EC value, so I just got the EC pen instead. PPM would be like 1300 I think?
good call, missed that bit but yeah, that's even too high imo as far as ppm's go, anything over 800 is unnecessary imo
With the reservoir though, you mean in a regular DWC, like a 3gal, its not worth changing the water? I didn't invent the method myself or anything, that was prob the most common search result on google when I looked for how-to. said to top it off with pure as the days went on, then 3 fresh gallons of PH'd, with fresh nutes once a week... how do you do it exactly?
i use 2-5 gallon buckets i fill with tempered water, set to desired ppm and ph once water level has gone down a significant amount, usually 2-5 days later (depending on stage of growth) i'll topoff as stated in previous post beneficial bacteria actually builds up in the res and dumping every week actually halts plant growth as they get acclimated to the new medium even towards harvest when it's time to flush i'll just add plain water at topoffs until ppm is next to nil these reservoirs were only dumped once, early on i had some issues when getting my tent set up but you can tell they are very pleased with their home. ppm 700, ph 5.9 topped off 2 days ago, when pic was taken View attachment 1730864
I saw your EDIT ..lol But I see what you mean. I guess similar to a fish tank, you don't neccesarily have to dump it once a week, but if possible, I'd still do it. If it's the same water, same PH, and its starving for nutrients, it would have much acclimation to do. I think it would love a whole fresh res. I get all my feeding numbers from the packages the nutes come in usually. and what seems to be the most popular on line. If I had a big remote res, I would totally understand not dumping it. Alright, I'm prob going to shut up and take a back seat to this grow journal now, lol.
i mean, they will still grow if you dump and refill (honestly, i did it my whole first grow a few years back, but not once since then) like i said, your just literally throwing money down the drain and, once you get in a groove; those nutes go real fast already a quart of nutes can last 2-3 grows instead of maybe 1
nice, I got the 400 and the 3ft x 20" x 5ft tent. I was trying to talk the OP into HID earlier on, you can back me up, lol
light will damage your roots, this is why the res need to be light tight just light hitting the water will create algae, and cause a various array of issues just a ph and a ppm meter is all you need really ensure you get some ph calibration solution as well
one of my concerns with the water changes, was about algae. It seems to be waiting for me whenever I let it go to day 8, without a full change. My res water might get a little warm some times though.
that'll do it temperature sways will increase the risk of issues gotta have a stable environment, took me a bit once i got the tent set up hence the dumping and refilling but now, res temp sits at 68-70 with lamp on and drop only 5-6 degrees and night time
hmm that's interesting mozey, see, since you started in a towel, your taproot is exposed. Mine tends to go south into the wool the second it's out, so not much light will hit it.
this is why i pop my seeds straight into the hydroton from the time they crack to harvest they never leave the net pot
It was a little better when I had my cool tube hooked up, but all the extra bulk and ducting got in my way, couldn't stand the noise of the centrifugal, and the cold season was here, so I went back to gull wing, lol. but now the res heats up a little to much.
