HELP! DWC growers Please Help!!!

The point of me saying it was "a waste, in my opinion" is simple. Plants, in soil or hydro for that matter, do not drink 5-10 gallons of nuted water per week. baring extreme weather or circumstances. Even at a gallon a day that's not all nuted water. Since many reservoirs are in the 5-10 gallon, I run 7gal, it stands to reason that if you change a similar sized reservoir every week there is waste involved. Beyond that a simple PPM/EC check shows they haven't used all the nutes in the water in a week, they generally haven't used even half, let alone a majority of the nutes, so again waste. It's simply a fact of any water/nute system it's just more apparent in hydro.

The absolute perfect conversion would be to let them drink the entire res. and then refill, but that isn't practical, and would be a nightmare to even attempt to maintain. So some waste is going to be involved anyway.

The plants don't actually uptake water and nutes at the same ratio day to day let alone over the course of a week. But you can get that ratio closer than changing every week, It's clear when you get close to right by tracking top off water against applied nutes. There's still waste involved but it's close to optimized.

That was what I meant, it isn't a deciding factor, for me, but it is a consideration. The deciding factor for me is being involved in that manner with my grow makes me track stuff and stay engaged and focused, which is both highly beneficial and therapeutic for my condition.

And now I must go kill a cat. The ass jumped the barricade and ate my seedlings. Ok he isn't going to die, but his ass is excommunicated until I get my 2nd tent...

These are great discussions :)
 
hi folks!
im mid bloom on my 2nd dwc grow.
5×5×7 tent, 1000w hps for bloom, ac ducted to intake, light cooling fan pass thru. carbon scrubber recycles inside tent.

dwc is a strange beast. anyone can set it up, and if ur a quick intuitive thinker even a new grower can get from a to b successfully. but getting true dwc results takes time to get a feel for how plants will behave in the system. you need to learn how to read ur plants and act decisively with any issues and training techniques.
by observing results of my actions in the tent i am learning to achieve and maintain the rapid growth associated with dwc and get awesome potency and ridiculous weights for a new grower.
my first run was a freakin juggling act from hell, but still managed to get over 2 lbs of badass night time smoke. emphasis on night time.
this 2nd run has been a breeze system wise, and im expecting similar weight and potency, only this time IM DOING THE STEERING!!!
i do not use a chiller. the only time i chilled down my reservoirs was to help speed up a root rot recovery, and frozen water bottles are enough for that. if your environment is set up anywhere near properly, ur res temps will always be less than average tent temps. cool air flowing around the res takes care of that.
also, i only use tap water. ppms are quite low here, so the only bitch i have is the ph buffers they love to throw in there. takes a day or 2 to stabilize.

i am a new grower on my 2nd grow. the magic and mystery of propagating great medical cannabis is rapidly being replaced by science for me. because it works. much more reliably than all the spells and potions and miracle combinations flying around out there.
jesus i ramble. and on the verge of rant... best finish now, lol.

DWC is awesome in concept. im just finding that it will take a.year or more of back to back grows to truly get a handle on absolute control of the system and get the most from my grows. just not one of those things you try out once or twice, lol.
 
Well-spoken, harvester!! An intensive, hands-on learning process with good observation skills.

I alternate between feeling both things about this plant: the science and the mystery of growing cannabis. Then smoking it.
 
" Plants, in soil or hydro for that matter, do not drink 5-10 gallons of nuted water per week". Mine do.
I'm about to harvest my second hydro grow. I use the GH recirculating 12 week feeding schedule 100%. Once the girls get into flower, I'm adding .5 gallons of pH balanced H2O morning and before lights out. That's seven gallons of water per plant added to a 2 gallon res per week. Sometimes they take more H2O, I change nutes every 5-7 days. One has (2) 300W LED's, the other a 315 CMH.
If I had hydro plants lagging in development behind soil, I'd be looking at light and air movement, if all else was identical.
I often do a flush when changing nutes at the end of the week. Two gallons of balanced tap water in the res for an hour or so, then empty and put in the nutes. I my head that helps clean things up a bit for the roots to be happy with the new food.
 
Ppms can be comprised of any parts that doesn't mean that they are the right parts. When I go to the grocery store I usually eat the stuff I like the best first.
 
I added over 2 gallons of nutrient solution a day to the plan in the picture.. I always top off with nutrient solution not water.
 
That's just it, all else isn't the same, there's an entire history of testing and abuse with those poor plants. They were never really meant to be harvested, that just developed over time as life situations changed.

I do like the idea of a mini flush.

As I said before I suggest switching every week, it's beyond doubt easier and safer. My preference is to not do so. As long as one is producing what they need at a quality they like, it's all good in my book. I put together a system that works for me, it does what I need it to on many different fronts beyond just the weed. This grow started off as a proof on concept putting together research and getting plants from clone to harvest upgrading from a couple sterlite tubs stacked together to a full blown tent. I can't even guess how many clones died as I practiced each skill in them, from cloning to manifolding and ScrOG to playing with nutrient ratios.

They may have had a lag at switch and still be that timeframe behind, which means they aren't still slow but as far as density, trich production etc. They're way ahead of the soil plants.

But anyways I just like to talk about how different people do things and learn new interesting ideas like the mini flush. I just wish the DWC didn't feel so limiting to me, which is what has spured me to go F&D. I think it's just something about having the plants in containers that works best for me, I don't really know, I'm just glad that DWC transitions so easily to F&D. lol
