you should be able to especially in early veg where the plants aren't that big. you could maybe go 3 weeks even.

Not necessarily. Some people grow via Shallow Water Culture (SWC), including myself in the past. The reason I see is to save on nutes. If I'm flushing every week, I would be flushing lots of unused nutes.
Roots don't have to sit in the water. The roots not submerged get plenty of water from the spray created by the bubbles popping on the surface. If you fill a bucket half way, and you have a good pump, the netpot should be dripping with water, even though the water level is quite a ways away. It behaves more like an aeroponics system in this aspect.

That's what I was hoping

What I've seen, from doing searches on the Lucas formula, is that a lot of people have used it for a long time and swear by it. I have to believe there's something behind this.
If you see a story on FB that you can only find a couple of backing articles, its probably not very believable. But if you see lots of articles from reputable sources, there's probably some truth behind it.

how tall are you planning on letting them get? is your tent 8 ft?That's what I was hoping

Probably around 18". Nothing out of the ordinary for a tent grow.

if you look at the formulas for GH maxibloom and GH floranova bloom and GH flora duo bloom recipe, they are all Lucas formula based.

you'll easily be able to go at least 2 weeks even in full bloom mode. even if they drink a gallon a day, your res is big enough.

Yeah, I saw the Lucas formula for the Floro Nova series. Might switch to that down the road.

Really glad I went from buckets (20-25 gal) to totes (up to 80 gal). I have you to thank for that

i'm pretty happy with my nute regimen: dyna gro foliage pro for veg (3-1-2) and then floranova bloom for bloom. RO water. only additive is Silica. happy plants without spending a fortune on nutes

i want to see the bud porn when you get done! what strain are you doing?

I plan on getting an inline RO filter(s) at some point soon. I've got a reservoir that I was going to use for the buckets, with a float valve. Now, I have no use for it because it's way too small to fill the new setup with the totes. So, I'm either going to get a 55 gallon hdx tote, which I'll fill with RO water, or I'll directly feed the totes with RO. I have to imagine the first would work better because of how slow RO water would be making 50 gallons on the fly.

Yeah, it's sheer genius, use a completely unbalanced nutrient mix. Why didn't any scientists ever think of that? They probably did but then said nah, that would be stupid, so didn't bother doing it.

let me know when and where you got your doctorate in Botany, ok?
keep preaching the Hoagland solution. i'm sure a 1938 formula for 1 week of tomatoes during fruiting is completely balanced for growing cannabis. do you use mercury vapor lights? they were all the rage in the 30's too.

Totally retro, dude! LOL
Seems that the Lucas formula achieves balance, just using a different method.

If any stoners were smart, they'd actually use the Hoagland solution. Been around for a while, pretty well tested by this point, unlike the mucus formula. Fortunately there's a fairly wide safety margin with nute solutions. They'll grow with just about any formula as long as all required elements are present in some fairly reasonable ratio, so the mucus formula won't actually kill plants, just not work as well as Hoagland I suspect. Apparently stoners have a dislike for scientists or something but they just love other stoners and follow whatever advise they might dream up.

Just an fyi, Floranova used in DWC makes a fucking mess. As it does in any recirculating setup. Clogs filters, leaves a brown coating on shit etc. I'll sometimes still use that one part when feeding via pump and water wand, but that's it.
For recirculating setups, I rock the maxi instead, way cleaner and cheaper than the floranova. The maxi is also cheaper and less complicated than the floraseries including the lucas formula.
All three imo have the potential to give identical results, as does the duo with the addition of more Ca and Mg. Might as well go with the least expensive! Maxi for the win.
There's so many feed charts out now for the floraseries.Hey all, I'm in week two of veg with my 60-gallon UC system. I was wondering if the feed chart below's accurate. If not, does anyone have an adjusted chart I can check out?
The original on the bottle formula called for a total of 30ml/gallon of the combined parts(3-2-1, 1-2-3). Waaay too hot. Most of us had to find out the hard way back in the day that no more than 1/2 strength was where it was at. So when trying different formulas that are out there, look for the ones that use no more than 15ml/gal of the combined parts. And since you're in dwc, even less.
