Hydro doesn’t taste as good as organic, and it needs to be flushed or you ingest a lot of nitrates, which is likely carcinogenic. Flushing requires careful planning and a system designed for it. You can’t just treat it like a fridge full of food. With soil you can just leave stuff in the ground until you want to eat it.

I’ve poured a lot of time and money into the hobby, and have settled on organic soil with some simple drip for indoor growing.

The water use is about the same. As long as you’re indoor the water has nowhere to runoff/evaporate to.

IMO the benefits of hydro/Aquaponics are nonexistent. Also, the whole system is a pile of plastics. The tote and drain pipe in the linked article are not food grade plastic, which would scare me away from this system.

The automation is way way way overkill. Hydro is very easy to tweak. The nutrient profile is a tiny percentage of the labor, and a $3 battery operated temp/humidity display is plenty for keeping things nice for the plants. They show the high and low since last reset, which is all you need.

If I had any outdoor space with good sun I would set up a greenhouse, but since I don’t have that I run leds directly off of solar panels on my roof (dc-dc step ups and downs as needed).

Kind of cool to see them rise and set with the sun.



Honestly, there is research out there that is a couple of years old that disproves the need for flushing. This is the first link I found. And the first of it's study that I know of. https://www.rxgreentechnologies.com/wp-content/uploads/2019/...

I'll see if I can locate the talk from Dr. Bruce Bugbee on flushing.


I’ve found that herbs like cilantro taste extra strong when unflushed (even I taste the soapy thing, which I don’t normally)

I take my cues from the cannabis hobbyists, and they’ve largely moved away from hydro because of the taste. Unflushed bud is known to be harsh, give a nasty headache, and leave extra salts in the ash for those who smoke it.


Regardless of growing in hydroponics or in soil cannabis growers still recommend flushing.


Doesn't "less tasty produce" from Hydroponics indicate a missing nutrient in the water, that they're picking up in soil? Couldn't this be supplied?


The plastic also scares me, who knows what’s leeching into the water from these non food grade plastics… endocrine disrupters and carcinogenic compounds would make me stick to simple soil


Who knows what's in that soil?

You can use the same plastics as in water pipes.
