First Grow: Linfa Weezy with Royal Dwarf

@Qenzhi, That‘s very true. But the Linfa box is a fully automated grow environment. The grower has no way of altering the nutrient supply or the watering frequency/watering amount. The latter could be done manually though. The water tank (the water level itself or partly changing out the water) is the only „tool“ a Linfa grower has to manipulate the nutrient concentration. That seems to me the greatest weakness of the Linfa system. I will probably start another grow early next year and if that one then also fails, I’m gonna curse myself for buying a Linfa and instead get a small grow tent.

@Honkytonky, I don't know what to recommend to you, considering you're a beginner. I'm not familiar with this growing system, but I'm sure that a decent result can only happen with good luck. I don't understand how this system can regulate growth throughout the entire growing period. After all, the plant grows, and over time it needs an increasingly higher concentration of nutrients, and you're saying it feeds the plant once a week by adding macronutrients. And if, for example, 2 plants die and only 3 are left, will the system continue to feed the plants assuming there are 5 growing? How does it regulate pH? Even feeding once a week, is there really a sensor in the system that takes samples of the nutrient solution to understand what the concentration of dissolved salts is right now and conclude how much needs to be added? I don't trust such a system, unless it's for growing basil.

@Qenzhi, The Linfa is, as it turns out, a fairly basic grow box with a lot of shortcomings. A “fully” automated one though. The carbon filter is a joke and is basically just a very thin filter mat. If one uses the box during summer, it is not too big of an issue since you can leave the window ajar during day and even night - dependend on the neighbourhood of course. There is no built in regulation of the ph-value or adjustment of the nutrient supply. It runs a pre-programmed schedule for the nutrients regardless of the actual usage. The only thing it measures during the grow cycle is the water level and it gives the user a warning message via the app once the water level gets too low. However, now that I slowly but surely get the gist of things, I’m optimistic that I can make it work for my next grow project. I have now purchased a ph meter and tds meter as well as a bottle of ph-reduction liquid and some nutrients for the blooming stage, that I can add to the water if need be. Next time I will be closely monitoring the ph and the tds-value right from the beginning. Both of which I can now manipulate up and down to the desired values. I am already curious as to how the next grow will develop. The current one I’m going to ride till the (bitter) end. Meanwhile more with experimenting than harvesting in mind. Thanks a lot for your help. Very much appreciated. Thanks to you and the advice of the other helpful commentators, I got myself the neccessary ph and tds meter. I realise now how important these items of equipment are. Funny you mentioned basil. That was, I gathered, the initially intended purpose of the box. As an afterthought, the people at Linfa added a very basic filter mat and put in a stronger LED light and thus gotten themselves into a new market segment. Two birds - one stone so to speak. The Linfa box is in my opinion only for the absolute micro consumer who doesn’t want a tent in their (small) appartment.
