@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.
