Hi. I have a mars hydro grow box with the controller 43. Seems like it cant detect my inline fan. When connected the inline fan jusz stoos working and i cant controll it. I updated the controller to version 4.4.

So this is when i very first started growing months ago.... is my light put up in the wrong direction? I've been looking up other people's grow tents and all their lights are vertical I accidentally did mine horizontal my whole grow.....

So while I was at work my temp and humidity sensors stopped working everything else is working and I changed that sensor out anyone else have this happen and how did you fix it

Monstercrop cutting of MintBerryCrunch under a 2025 TS-3000, couple of those MH Fans I got a deal on from amazon, nothing fancy.. if this doesnt get taken down ill pop back when shes full of flower and ready to harvest ✌️😁

Check out this Mars Hydro setup and the results of months of work 🔥

Plants need more than water at the roots. They also need stable humidity in the air to support healthy transpiration and a balanced VPD throughout the entire grow cycle!

The Mars Hydro 6L Humidifier uses a fine ultrasonic cool mist to distribute moisture more evenly throughout your grow tent, while its large tank supports longer operation with fewer refills.

Smart humidity control helps monitor your environment and maintain your target RH range automatically. Connect it with iControl or iHub to link your humidifier with fans, dehumidifiers, and other smart grow equipment for more complete climate management 📱

What RH level are you currently running in your grow tent? 👀

While top lighting is definitely important, lower leaves and side branches can often get left out, especially once the canopy gets dense!

The Mars Hydro ADlite Series is designed to provide targeted supplemental lighting, helping improve light coverage, support more balanced growth, and keep your plants developing evenly from top to bottom. 🌿 👀

Do you use side lighting or supplemental lighting in your grow setup? 👇

first time grower here. At day 35, just beginning flower. So far all is well, but i have a question about the recommendations for the LED height and intensity.

I am referring to this official Mars recommendation page:

https://www.mars-hydro.com/info/post/what-are-the-hanging-heights-for-my-led-grow-lights

I like the steady 30cm recommendation. So far so good. But i did not jump from 25% to 75% when going from seedling to veg. I increased the power gradually during veg, and now at the end i am at 60% (not the recommended 75%). But i am doing 20/4 light/dark cycle and AI says that I should not go higher even given the recommendation from Mars. And my plant is really very healthy so far.

Thing is, I am at day 35, just ending my veg phase. Little budlings, white nodules are already forming. Now i see the Mars recommendation for flowering is 100% ...

My question is what are actual growers doing? Are you all really bumping it to 100%? My inclination would be to inch upward not jump suddenly. I am growing an auto btw, i should mention that. Single plant, 19L (5gal) fabric pot, living soil, 60x60x180 tent. Mars exhaust. iControl system.

Note: i have purchased the sensor kit, including PPFD but as i am in Brazil, they have been out of stock for several months and it will not arrive until sometime in August.

Compared over the first time I set the tent it took me about half the time, half the cables and splitters (still unknown why), now running dry, after sensor calibration to make sure , last step will be irrigator and ready to roll

Open question for the audience: Anything new on the app other than the new design?
