DWC NUTRIENT RECIPES FOR HEALTHY FLOWERING

legallyflying said:

I am doing dwc... Or rdwc... lots of buckets and a central rez. It's a super duper top secret special technique.

It mixes once an hour but not continously.

Well, I never ever never change my Rez unless somethinh is wrong so I just add the tea weekly.

You put your circulation of DWC on once an hour? Why?
You never change the REZ? I am always scared of salt buildup and whatnot. How do you prevent this?

I can't avoid salt buildup personally. You'll always have dead roots and such. I run my RDWC 24/7. I am sure I could change my water pump to 30 minutes on / 30 minutes off or something but dont have a problem with it currently.

Use the main RDWC water pump to empty most of the water and than use a wet vac to empty each res. This is assuming you can pick your plant up and put it else where while you vac it out. I am able to disconnect my output from my water pump and re-direct it to a 20gal brute on wheels. =) System works well for a first go-around.

I really don't know what you mean by salt build up. If the rez gets a little too stron I add water. Little too weak, add nutes.

If you have the ppm dialed then it should stay pretty damn stable.

So my system us basically ebb and flow, but reversed.

200 gallon rez for 16 10 gallon trash cans. It takes about 100 gallons to fill all the buckets so 100 left in the rez.

The rez is chilled to 65.

Once an hour all the buckets empty into the rez, the returning water is about 67 and the buckets are filled back up...water now 66.

When there is only about 50 gallons or so in the rez I empty the buckets into the rez, add water and nutes till its full again and I'm done.

The large volume of nutes helps buffer swings and regulate temps.

I do NOT have dead roots or salt build up. If you have salt build up your nutes are too strong. Water and nute uptake should be balanced.

Hmmm... I can dig it. Seems that your system would help keep the heat production to a minimum. I just run my DWC with a float valve hooked up to a 10 gallon bucket that backfills with plain water, and it allows me to monitor exactly how much they are drinking(16 plants usually drink about 4 gal a day). I have never had problems with salt buildup at all, but I have always run the nutes light and use dripclean. My chiller is in-line with the systems circulation so it runs pretty often in the summer, and I wonder if I dropped the temp setting and put the pump on a timer if it would help with heat. What do you think? Here is a pic of the system

The problem is likely your eco plus chiller. It looks like an eco plus anyways.

I'm not really following how your system runs though.

All of the buckets are in-line with 3 inch connecting each one at the bottom, and a pump pulls from the end of each row, through the chiller, and back to the rez. It is an eco plus, and honestly it hasnt been a problem at all. When the water is constantly moving, I would imagine without a fully insulated system the chiller would have to work a lot no matter what, and thats why I like how you have a bigger rez to help buffer and retain temps. I remember seeing some of your pics before I think, barebulb verticals with the brutes on buckets, and that shit was sick. What brand chiller would you recommend? Got some better pics of the system? I remember wondering where the heck the rez was.

What chiller do you recommend then?

GH Flora Nova Bloom and Great White to help out the roots. thats what i use in my dwc setup

you could wrap your buckets in reflecttx..that silver bubble wrap at HD. That would help a little plus it bounces light around. If it's working fine I wouldn't worry about it.

We use penguin chillers. I take some pictures on monday when I go visit the room. Our Rezs our outside the room and it's like 50 or 40 at night so that I helping for sure. Summer time will be a different story I'm sure.

how cold is too cold for the res? i just checked the temp of my water and it was at about 56 degrees farenheit. I also have all my 5 gal buckets wrapped in that reflectx stuff its pretty great i think lol.

Way to cold. Slows down metabolism pretty badly. I would never go below 60.

not trying to im actually trying to warm them up. kinda cold outside which is making it harder to keep them warm. but thats good to know that 60 is the lowest i should have it.

just went and checked it again and its now at 57... i dont think ill have this problem when i put my hps lights in there. should i put a heater in there or maybe use some heating pads under the buckets?

My EcoPlus chiller automatically warms the water as well

when using lucas method and adding ewc tea..would the tea be considered as adding more veg or more flower..i understand its microbes but there is a nutrient component that the microbes create...

I suppose it depends on what you put in your tea, but usually there is not much nutes in there. I keep it simple and brew with a powdered micro benny pack of your choice, floralicious, and Ancient forest. Works great for me.

I wouldn't sweat it.

Isn't floralicious just a maxed out fulvic and amminos? Which I'm imagining if left brewing long enough would Just be food stock for the good guys?

all I know is a gallon of black strap molassis is $8. I'm quite certain florolicious is more than that.
