Ive never done a recirculatory but from the Hydro section on here most agree that DTW uses less nutrients over a growing cycle than Recirculate. A little run off here and there vs the dumping of the tank every few days/week.
I get the odd power outage and im a lazy grower so nt for me- id love to give it a try one day but id have to be more motivated.
There’s an abundance of misinformation and guys not doing recirculating systems properly out there. If you use the right nutes, have the correct size res then when you go to dump the res there’s only a bit left in the res. I.e just enough to cover the pump on a feed cycle. I’d say that would be equal to or more likely be less than what you’d use in say a DTW coco with 20% run off. You’re still using same EC so the argument of using less nutes is null.

The best hydro systems for using less nutes and h2o IMO is DTW high pressure or air assist aeroponics. And 0 media / substrate

The more i read about RDWC the more i like the idea although noise from air pumps and a decent sized water pump would become an issue not to mention getting the money together for it all as theres allot more involved then just getting some good lights an banging seeds into some soil mix. Either soil or soilless medium i would run a res on dtw setup an only need a smaller air pump to oxygenate the reservoir tank. All that said though still would be alright to give RDWC a crack.
It’s up to the individual grower but personally I just find it more work and effort than it’s worth.

with recirc you should be replacing the water/nutrients in the res as the plant uses them. Like if it’s hot and the plants using more water than nutrients the ec gets higher in the res and causes over feeding issues, if they are using more nutes than water the opposite. Sounds like your running your recirc system the same way most would run a dtw res. With a 100l res I’d get a week+ between res changes and no fluctuations in the res because the res has no inputs other than it being filled so no need to check ph and ec each/every couple of days

I don’thave any issues with it. Some think it is but plenty of guys have run it from start to finish with no issues. I’ve done multiple runs with just megacrop at its recommended dosage and no additions a few times with good results, I just getslightly better results if I adjust the levels in flower slightly to get the nitrogen down a tad.
I use megacrop...bertha has no.issues with it I
I will.stop using it by the 2nd week.of flower

I gave NFT a crack once. Growth was amazing, but had trouble keeping the res clean and ended up with heaps of little critters living on the roots. Went back to the tried and true coco after that.

having done both recirc/dtw with aero & coco I’ve found I use less nutrients and water as well as have less issues running dtw coco even with 20% run off. The coco acting as a buffer and it holding water means I need to feed less per cycle and have less issues if a pump fails/power loss etc. my goal is to keep the coco saturated with nutrient and use the cocos ability to hold do to my advantage.

$400. They will do the job in my small ass tent, probs 2 plants in 3 gal or maybe 4 in 2 gal sog. Tents only 3ft x 1.5ft
if your absolutely adamant on going that direction than yeah it’ll do the job. A single highlights board would be over kill for that space but. You’d probably only need to run it at 150w (which would mean you could get away without a heat sink on those particular boards) and run it closer to the canopy

anyone know if this is any good ?
It's great stuff
Not a fertilizer it acts to get all the goodies in your soil pumping ...kinda wakes em up
Add 25% perlite to soil
2 cups rocket fuel pellets
2 cups seamungus pellets
And u have a great soil mix for outdoor once you feed go go juice weekly to the soil
Pellets above are all nuetrog brand
Can also get seemungus juice for feeding

basic but it’d get the job done.

I don't use that mix now but 5 years ago I used to for fabric pots outdoors
personally I’d add more products. But that’s because if I’m using soil I like it to be as complex as possible for the microbes to have an easier time breaking it down.

Yeah but Nah :lol:. I totally get what your saying, and for most they would have to add water to the res and quickly that would bring the EC down. I don’t advocate adding nutes to a recirculating system ,as it just screws the nute balance, and you start running into other issues.
If you’re indoors hydro then to me the goal is to have your environment controlled, and every aspect of your grow dailed in. If you run a really tightly controlled VPD then you don’t have to add anything, including h2o. Just adjust ph for the first couple of days and then off you go. I get 12-14 days odd out of a 220 litre res on a 4x4 table.
What dictates a res change is when the ph falls out of range 5.5-6.5, or the level in the res gets too low to pump a feed.

Canna Aqua is unreal for this type of system.
