Why cant i achieve huge autos in dwc?

Been growing a few years but every time I dip my toe in the dwc tote my results are less than satisfactory I started in coco and averaged 7/8 oz an auto ( why didn't I just stick with that) got bored tried and failed dwc then went to living soil still hitting 5oz + a plant got bored tried dwc failed went back to soil got busted set up again dwc just getting somewhere got busted again 18 month on got bored caution from 1st bust slap wrist for 2nd fuck um I say so here we are again dwc plant looks healthy enough just not getting these amazin results I see
Barney's farm critical kush auto in a 19l oxypot good fizz from air pump water temp stable 20° ec 1 pH 5.8, 3x3 tent extraction circulation steady 26 ° on the picks the 2 photos in coco are great the auto just looks stunted to me to boot 8/9 wk is now on wk 14 and nowhere near ready yet wtf am I doing wrong???

Hydroponics gets bigger yields from accelerated vegetation. Photoperiod benefits the most from it.

Hydroponics does not give better yields per se. So auto flowers do not get more yields with no elongated vegetation period.
The only benefits I can see using DWC for auto flower is to manage all nutrients and supplements, and if the right container is chosen can allow infinite root availability to maximize healthy root growth.

You should.be getting better or same results with dwc.dwc just keeps the root allways full of o2 and nutes.if you made mistakes with feeding that could make them grow slow

There's definitely something going in with your grow but some info is needed to try to figure things out.

Are you still interested in resolving this issue?

The auto finished but didn't yield much the calyx never swelled properly I've just cut 2 phots in coco down n am gonna try dwc again now with a clone see what I can do

Great attitude!

DWC has more "moving parts" than soil and coco so perhaps something went sideways in your setup. I realize that this wasn't your first grow but something might be amiss in your grown environment. It could have been the seeds but the attached graphic might help you to get everything set up correctly. It's not my handiwork - it's a screenshot from a Bugbee video.




Funny thing about your grow - the plant had good foliage so I suspect that a lot of the "parameters of growth" were good. Running through the numbers - 5 gallon buckets (good size), water temp good and oxygenated, wind OK, and pH good.

The amount of foliage indicates that it got adequate light but that's faint praise - what PPFD were you using?

What about nutrients - they look healthy so that tells me that you're probably feeding them at the "sufficiency" level.

What's your process for res maintenance?

Am thinking I went overboard with the juice my ec was up around 2.0 in flower she never indicated tho only the slightest bit of tip burn she just seemed to pause about week 4 of flower for a a couple of wks then limped over the finish line with about 40% amber but hardly anything you would call a swollen calyx hey ho live and learn am gonna try n get it right with a photo p 1st then try auto again ive bust 10 Oz off an auto before but in a 50l fabric pot in coco with nutes she ran 10 wk in veg then 8 wk flower giving me just over 11.5 Oz and I see these triffid like autos done in dwc and feel a touch of jealousy lol ill get there one day

I don't have the facility to measure ppfd acurately I run qbs Samsung diodes meanwell driver 240 w In a 3x3 my buds are firm enuff, I picked a couple of clones up earlier am gna try again lol

As for res it's a 19l oxypot changed fortnightly in veg then just topped up thru flower until last couple of wk swapped for phd water ph never went below 5.5 or above 6.5 whilst being fed ec stable seemed to be eating and drinking at the correct rate like I say am pretty sure too much juice my prob a pal of mine never goes over 1.0 and smashes it 20 Oz plus per gal so am gonna work with his feed sched this time I don't go for all the voodoo juice 10 part bollox, just veg n bloom 1 part dry food and their shine for flower

Thanks for the info.

Res maintenance sounds good - two weeks for a 19 liter res sounds about right.

Same here on the nutes - no "pretty bottles" for me. I switched to jacks (dry, two part fert) after my first few runs. No need to pay to ship water around.

EC 1.0 is pretty low. I start with 0.6, second res will be 1.2, and I'll hit 1.6 in flower and then back down. I feed through to harvest because the plant is still respiring but that's a minor issue vs this grow that never really got off the ground.

RE. 20 oz - I look for 16 oz and up per grow. I do one plant in a 2' x 4' res and I "feed" my plants well meaning that I get them to 900µmol ASAP. As with the different in nute levels, the difference in light is not why your auto stalled out. At this point, it sounds like it was genetics.
