RECIRCULATING DWC ANYONE?

I dont think im doing something right. I have about 8k watts dedicated to flowering yet ive never harvested over 3 pounds so yes im most definitely doing something wrong.
seriously?

wow. i would do like legally flying said and try like an ebb and flow . there are tons of setups on the internet with a 55 gal drum, a bunch of buckets and a controller. i,f you have 8K dedicated to flowering, even at .5gpw grams per watt you should be pullling like 7 lbs.

In situations like this it's usually a combination of factors. One big one is environmental control, another is 'too much' syndrome.

Can you tell us what/how you run your op and I'm sure we can help pinpoint some areas for attention?

What ttystikk says.... is this on DWC single buckets? If so, under that kinda light.... whats your water temps? That was the bane of my first attempt @ hydro... is Ph monitored regularly? Air cool n fresh? (or co2 infused)

Whats up bro ... I grow in waterpack acs .. Thats 4x waterfarms connected together and to a main controller reservoir with another topoff res over the controller res. Its by GHE .... I modified the waterfarms by enlarging the draininh holes which will allow yhe roots to grow and dip into the res (in a DWC fashion ) .. its starts as NFT then becomes a combo NFT and DWC ... the hrowth is amazing .... no water pumps in yhis system just airpumps .... the mechanism used to recirculate yhe water ajd also to drip it from the top actually enriches it with more aeration ...... it doesnt have to be THE system for you, but it certainly is worth checking out!
Happy growing bro

Check out my current TriStrain grow:

Well i just ran 16 hydros under 6k watts of light and i pulled 3.5 pounds. I use dwc, my buds came out very tight and nug like which i was happy about and the smoke was great. maybe its just not a high yielding strain. I make sure my ph in my buckets stay between 5.8-6.2 never higher or lower, i dont really measure my ppms. I keep my water at about 65 degrees. I dont scrog, however i did lollipop them. I only vegged them for a month as well. I just added in 2000 more watts of light, i used all air cooled hoods, but i just switched this run to parabolic reflectors that hang vertical or horizontal only because the temps are dropping and i want to expose them to the light directly. My last strains i ran were white widow, amnesia haze and ladyburn 1974, i got rid of the lady burn and white widow.

Any tips on helping me get better yields would be appreciated, in the mean time ill explain what im working on and my new strains, its something im trying to increase my yields. I created a 8x4 scrog net, i have 3 dwc's under it in 18 gallon totes i modified myself. I modified the buckets to have a drain valve and also a hose so i can always keep an eye on the water level, ill be pumping water into the buckets so that i dont have to move them once i start the scrog, if i successfully fill out the 8x4 net which is under 2 600 watt lights im sure my yield will be pretty good, i have 4 600 watt lights in total in this new room. on the other side im not doing a scrog im doing a regular grow with 3 dwcs and im comparing which way is better and im going to scrog them the same amount of time, i feel like right now im just wasting energy because im not getting the yields i desire.

Ummm.... shit, where do I start?

I was where you are a couple years ago and went off in a direction few would try... and yet, as the famous guy I don't remember whose name said something about the path less traveled by which made all the difference.

First, get comfortable with the inverse square law; light intensity decreases as the square of distance. This effectively means that the window of effectiveness under various forms of light can be pretty shallow between too close and too far away.

Your lack of ScrOG effectively meant that you were wasting a lot of light, and thus did not get the yield you sought.

The point of ScrOG techniques is to maximize the plant's growing surface area- that's leaves and buds- at just the right distance from the light. Too close creates shading and risks scorch, too far is larfy and fluffy.

Are you adding any co2 to the environment? It makes a big difference.

I used to run an undercurrent system with 600 watter and I would pull about a pound from 4 plants. I used a 2" pipe to connect all the buckets to the res. I pumped from the end of the system back into the res. not out of the res into the buckets. The pump used a 1/2" pipe.

The pipe basically created a U shape from the res. The 1/2" pipe ran from the center of the U back to the res.

It was kick ass system.

We use co2, about a month of "real" veg..I mean, the roots are in the water already. 48k watts in our flower room. 2 lbs a plant id what we hit when everything runs as planned.

The key to yields, in ordet of importance are as follows:
1. Strain
2. Maintaining distance to light
3. Use of co2... PROPER USE
4. Training
5. Training
6. Training
7. Proper nutrient management. And I mean some serious studying on cannabis nutrient needs.. not trolling fuck head threads about this brand or that brand. Mag to cal ratio, sulfur content, and N to calcium are very inportant. People that preach high phosphorous in flower are sooo fucking far off base it baffling. I should make a t shirt for growers that days " Got tissue analysis?"
 
A cheaper and less pain in the ass system then constantly recirculating is to use a central rez with a ebb flow control bucket.
Set it to drain and refill every hour. You can chill the rez with a chiller. This way you can make all your rez adjustments easily when the ssystem is drained.

This way you skip the big expense of large pumps, 4" water lines, and gaskets, roots clogging the water lines, and trying to ph balance the water without burning the hell out of the roots, and maintaining the right water levels.

You need the folowing:
1. Ebb and flow control bucket... the diy kit from aqua hub is excellent. $110.
2. Bunch of 3/4 tubing. $40
3. Two mag drive 3 pumps.. $100
4. Penguin 1/2 hp chiller. $400
5. Pond master 100 air pump $120?

DO NOT, I REPEAT, DO NOT TRY dwc without a chiller. The penguin chillers fucking rock! I would shoot for 65 degree water. We have had MUCH better results with colder water.

If only i could fit that in my bedroom lol

It may be tough. A 55 gallon drum would do it though. Better than constantly topping off ypur system. Plus a water pump running continously is not a great thing to have in your bedroom.

No Co2 as of yet but im going to look into it.
