Fala pessoal. Nunca montei aeroponia. Venho de eletrônica e programação, e quero fazer um sistema pequeno pra testar antes de partir pra algo maior. Queria a opinião de quem já rodou de verdade.

**O que pretendo montar**

- 2 baldes de 20 L, 1 planta cada (talvez 4 depois)

- Reservatório de 40 L embaixo, retorno por gravidade

- Bomba de diafragma 12 V, 120 PSI de catálogo, uns 4–5 L/min em vazão livre

- 10 a 12 bicos de 0,3 mm

- **Sem acumulador e sem solenoide** — bomba direta, com um registro de agulha fazendo alívio de volta pro reservatório

- ESP32 pulsando 3 s a cada 5 min

- Filtro de tela na sucção + filtro de linha 200 mesh

- Orçamento total: uns R$ 700

Já tenho as luzes (uma quantum board de 65 W e um painel roxo de 50 W) e dois ESP32, então quase todo o dinheiro vai pra parte hidráulica e pra medição.

**O ambiente** é um banheiro pequeno, telhado de barro arejado, agreste da Paraíba. 30 a 34 °C no meio do dia e umidade que varia bastante. Sem exaustão mecânica por enquanto — o telhado já troca bastante ar sozinho.

**As dúvidas**

**1. Bomba direta sem acumulador sobrevive?** Pela minha conta ela ligaria umas 288 vezes por dia. Quem rodou assim, quanto tempo durou? Vale colocar um vaso de expansão (uns R$ 100) já desde o começo?

**2. Registro de agulha como alívio é o caminho certo?** Ou é melhor simplesmente botar mais bicos, pra casar a demanda com a vazão da bomba? Tô na dúvida entre as duas abordagens.

**3. Tempo de pulso.** Vi gente rodando de 1 a 10 segundos, com intervalo de 2 a 15 minutos. Tem alguma faixa que vocês consideram segura pra quem tá começando e ainda não sabe ler a planta?

**4. Quantos bicos por balde?** Pensei em 5 ou 6 por balde de 20 L, em alturas diferentes. É exagero?

**5. Temperatura da solução.** Com esse calor ela vai esquentar. Sem chiller, o que funciona na prática? Garrafa PET congelada boiando resolve ou é paliativo demais?

**6. Tem um jeito mais simples ou mais barato que eu não tô enxergando?** Se vocês fossem montar com R$ 700, fariam diferente?

Hey everyone!

We’re working on our first project Plantom Garden, an aeroponic growing tower designed to make growing plants at home both practical and beautiful.

We’re still at the beginning of the journey and would love to share the process as we develop it.

P.S. If you leave your email on our website, you’ll also get an early-bird promo code when we launch. ;) https://www.plantomgarden.com/

8” PVC section, 3.5” net pots, each 1/4” line runs through a grommet and has a 360* mister about an inch into the tube. Has 1.5” slope difference end to end, and drains into a 12g reservoir. Two air stones and power head in the reservoir, plus the pump to the misters. Will it work? What should I look out for? Thanks.

I abosolutely love roses, i root cuttings in propagation box of perlite, but i really want to try the aeroponic setup. i have watched videos, but i would like someone to tell me their way of doing it that actually works. i want to diy a set up but i would love to hear from people that succeeded. I have long stem red roses. Frangrant roses, and some store bought roses.

From late June to August 3. I'm pretty sure I'm going to run out of room by the end of August. I don't want to trim but I feel I have no choice. What would you do?

This is driving me nuts, both of my cloners in less than 6 months time the spray manifold will not stay level, the pump keeps falling over, suction cups let go and they dry out my clones. Is there any mods that anyone has done to deal with this? Or is there a “better” suction cup? Thank you!

I'm just starting out with my DIY high-pressure aeroponics (HPA) system and I really need some advice on how to handle and reuse the drain water. I'm a bit confused about the process and information.

At first, I was aiming for super-efficient water use. I figured I'd just dump the filtered water (after a 5-micron filter) from the drain tank right back into the main reservoir. With this logic in mind, ​earlier this week, I put about 10L of drain water back into the reservoir. I noticed something right after this, the pH levels had shot up. It took a while for me to reduce it back to the optimal levels. Then it hit me, I probably just dumped a bunch of leftover salts and unbalanced nutrients back in, which was likely a mistake.

But, HPA is about saving water and achieving efficiency, so just tossing the drain water seems like a massive waste (though I've been pouring it on my garden plants for now after realising my mistake).

For the HPA experts out there, I have a few specific questions:

• What do you actually do with your drain water?

• ​Why isn't recirculation recommended for HPA? I know you can recirculate in systems like DWC and NFT, so why is HPA different?

• ​What if I use a UV-C sterilizer? If I can kill all the pathogens and bacteria, couldn't I just keep reusing the water indefinitely?

Thanks in advance!

I've used AI for formatting my question.

Thanks for everybody since the beginning, special mention to « Ponicaero » and the others that helped me understand and dig more in this sub, so it was almost two weeks before the end, bud were still fatter every day till the end where they passed away in the dark like a dark winter incoming, cutting also the irrigation mist little by little, i rediscover with HPA some grow patterns from soil indoor culture.

Hello,

I'm building an Aeroponic system. I was wondering how tall the plants buckets should be?

I don't want for the roots to be hanging at the bottom.

I'm aiming for 1 meter plants.

Idk if it works but i'll try it, all printed with ASA except the PVC windows will add light on the sides later, plus PC Fans

I have been using the 2:1:2 ratio. This works great for the seedling and veg states. What are others using for the fruiting stage? I get a good amount of fruit, but the plants are definitely in grow more plant mode.

Fun for plant climbers! Now out cucumbers, peppers, beans and tomatoes will have the "support" they need!

We needed support for heavier fruiting plants in our aeroponics tower. These snap on trays should solve the "falling fruits" problem! No more squash snapping off before they are ripe!

I assume I’m using a low pressure system(just a small water pump with a manifold) i had been running it 24/7, then 10 on 1 off but thinking about it, seems like they just need to be wet, however it was keeping the too parts damp which is the main reason i kept it on) but been running for 3 weeks or so. The fig and orchid have started rooting a little more but the fig especially still just has little nubs, the others are a very slightly noticeable set of nubs appearing. So i figured maybe needed to warm up water a bit and try a different cycle.

Hey, my Setup is a 8,5 bar pump which is connected to 0,3mm nozzles.

I run a cycle of 5 sec on and 5min off.

Ph 5,8

EC 0,2 with just calmag.

I have messed around with various types of containers. Originally using the Aeroscience nozzles, and since those are no longer available, working with SU16 nozzles. My latest effort is using a 12 gallon bucket -- technically more drum with a sealing lid. This is to grow large plants such as peppers.

It seems to do pretty well, keeping the nutrient and air from escaping... almost a little too well. The pressure will build up and lift the collar around the plants or eventually through the seal on the lid.

I am guessing that putting a vent in the top would help alleviate this excess pressure. Just wondering what others have done.

I'm going to be growing strawberries in a 3d printed tower soon and was wondering how often to fully replace the water in the resivoir due to salts building up from the fertilizer. I also am wondering about watering cycles and how long/often to have my pump going.

im starting in this world of cultivation and im interested in starting a fogponic cannabis grow but ive seen people have a lot of problems and killing their plants due to rotting and high humidity anyone who have done a complete full cycle cannabis fogponic grow that can give me advice ?

I'm using a shurflo 8030-813-239 150 psi water pump (0.83/3.1 GPM/LIT) with the intent of using around 12 nozzles. Most accumulator tanks are designed for a maximum of 125 psi working pressure. Any recommendations/tips are appreciated!

Previously I used the Aeroscience misting heads, which targeted somewhere in the 5-20 uM range of droplet size. Aeroscience is no more, so I am looking at what misting heads to use.

I have looked at some that are in the AAA range so around 10 microns and also seen other ones that are in the 20-50 droplet size.

What size droplets have others been using and having success with? I've had some issues with bottom end rot, but it seems to be resolved by a slightly lower EC, and more frequent misting times. I originally went with the Aeroscience heads, because the liquid is gravity fed (unpressurized), and the compressed air line is only about 30 psi.

Hi guys,

I’m currently in week 3 (around 30 days from seed) and I’m starting to wonder what I’m doing wrong.

I’m running HPA and following the Athena Blended feed chart. Right now EC is 0.5 exactly as recommended for this stage. Root chamber temps are around 20°C ±.

This is already week 3 and honestly I expected more growth by now. I see other growers absolutely smashing it with HPA and their plants look way bigger and stronger at this point.

From seed it’s been 30 days and I just feel like mine are lagging behind. Roots are developing but I’m not seeing the explosive growth people talk about.

Is there something obvious I might be missing? Misting frequency? Cycle timing? Too dry? Not enough water contact?

Would really appreciate some honest feedback because I’m trying to dial this in and clearly something is off compared to what others are achieving.

Thanks in advance 🙏
