UPDATE: 29/10/2023. After a few months, i need to say it make the job done, but don't recommend for planting more that 2 plants (If they are big plants). It's a good machine for initiating plants but not for long terms because of the 3L tank and the plants drops out a lot of water in 1 week. Buy another brand with 5L+ tank___________________________________________________________________________UPDATE: 26/06/2023. After submitting the evidence of my issue, the support team contacted me. Performed a drive replacement immediately. I am surprised at the speed. NOTE: I need to test the new replacement.Now, after having two weeks with my old hydroponic, I would like to complement my comments:1.- The QR Code is in the manual on the back with the activation code.2.- The water leveler does work. If for some reason it doesn't measure the water correctly, just gently move it clockwise until it rises. I confirm that they are 3L of water.3.- The- water pump needs to move the water a little. If you see that your water pump does not move anything, then it is damaged.4.- Coriander Seeds: Never put aluminum foil to start planting seeds (I DID IT AS A TEST TO SEE WHAT HAPPENED) Fungus came out. The seeds that were not planted with the aluminum foil are growing without problems. I suggest once the seeds are planted not to move the top. So far, it has been growing for 8 days and the seeds are just opening.5.- If you need support with the company, go to orders and then to "Get Support"I will continue testing the performance of the hydroponic to leave a final comment, which mentions all the evolution, so far I am very satisfied and happy with my purchase. I am very sure that I will make a new purchase!_____________________________________________________________________________UPDATE: 24/06/2023: After thinking my water pump was a low noise, it's dead first because it don't move any water. I have right now 5 days with the hydroponic grow system, but i don't now if my seeds will grow correctly. I contact the seller and send the video they ask for. So i will change my rating later when they aproach to me and see whats happening or offers a solution.UPDATE: 22/06/2023 I must comment, that I have never had experiences with this type of "Hydroponic Growing System", I bought it because the price attracted me and I discovered that it was the best value for money compared to other brands (12 pods) (However, there are other very good brands too). So I will be commenting according to my first experience of use, reference to the concerns or difficulties that I had, since they are not clarified in the manual.Checking the official page has important information about your product, although I did not register directly. Just visualize the information in a quick way, but from what I read it has vital information.The second thing I noticed was how beautiful it is, however, I was so excited that I wanted to get everything going at once (and that's what I did). However, I was surprised that this machine does not have seeds, the seller has it specified in the description, fortunately my mother had coriander seeds at home and I was able to move forward.These were the steps that I was solving as I was assembling:FIRST: READ THE MANUAL to have the minimun understanding of whats you need to DO.TEST LIGHT AND PUMP WATER: check the leds on and off and the pump is active before continuing with the following steps.LED bulbs: remove the plastic that covers the led, otherwise the seeds will not grow. I did not realize it for my happy emotion, if I had not read the Amazon comments, the plants would never have grown and possibly I would have gotten frustrated thinking that the machine was not working, I have seen many comments about this, and it must be that they did not move that Protective plastic.LED schedule: I have tested the schedule of the lights and indeed the vegetable one lasts 16 hours on and 8 hours off. (I haven't tried the fruit/flower option yet). Time cannot be set. Simply turn it on at any time you want and it will start counting from there.Water pump: My first difficulty was that, in the manual, it does not indicate how the water pump should be placed, however, it does bring a sponge (the longest one must be placed around the pump) to prevent it from getting stuck. move and make some kind of noise and the short sponge you should put it in front. (There is 1 more spare). In my case, the pump seems to be not that powerful, which makes it very quiet (very good for bedrooms) but maybe not so good for plants. Above you must place the lid with the two tabs that hold it. Suggestion: plug it in and test it before filling the tank.Water level: In the manual it says that the capacity of the tank is 3L, however, the manufacturer tells us not to fill up to more than the "MAXIMUM" capacity that is marked, and in my case that was 2.25 liters of water. If the tank was filled more, the water would have been thrown out when placing the gaskets. It is important that you read the manual to know how the placement process is. (CHECK UPDATE)PLANT FOOD: I fill it with filter water (normal water) up to where it ends at the top of the release in the bottle, (it is suggested to shake very well)Add water: I did not have a water meter, what I did was fill it up to the "maximum" indicator, I suggest that you fill it to 2L so that you put 10ML of plant food for each bottle of "food" plants. READ THE MANUAL.Once you fill the water and have placed the plant food, you can continue with the sponges where you will place your seeds, I placed the sponges in water for 5 minutes, I soaked the seeds for 1 hour. It is advisable to leave the seeds soaking for 12 hours and then place them in the sponges 3 seeds per sponge, and cover them with their cover.Once these steps were completed, I turned on the machine and it is currently in the germination phase. I will be uploading progress in the future.IMPORTANT NOTE 1: To prevent the growth of algae, cover the holes with black electrical tape (from an electrician), since otherwise, you will be promoting the growth of algae.NOTE 2: I don't bother solving these inconveniences since I come from the world of 3D printing, in fact this allows me to learn more about the machine, however, it can be somewhat stressful for people who are not willing to take on the challenge, in my opinion They were manageable inconveniences and that's why I rate it this way.NOTE 3: I have seen many comments, where apparently the LED bulbs are not of good quality, after 6 to 12 months they stop working, I will be updating as some type of problem arises. For now, I have just 3 days with the machine and cannot talk much about this point i will see the evolution.
