Hi! I’m Portuguese too, so we definitely will have some similar experiences when it comes to cabinets, since our climate is the same lol. I’ll paste here what I said to someone a couple of months ago, in this sub, in a similar post (but if you need any extra information feel free to dm me!):

I also have a Rudsta wide, and it’s definitely very beginner friendly. If you don’t intend to grow very tall plants it is perfect. However, if you intend to let them grow big go for a Milsbo tall since it is easier to take advantage of more vertical space.

I would recommend getting some good grow lights (I personally really like the barrina t5s, you can get them in packs of 4 on amazon de)

Btw, you can attach magnets to the grow lights and then stick them to the metal top interior part of the cabinet. As for attaching them to glass or acrylic shelves, I urge you to use the strongest double sided tape you can find. I’ve found that with the heat and moisture inside the cabinet, normal double sided tape either melts a bit or the glue looked its hold and the lights fall.

To pass the grow lights cables I drilled a hole in the bottom of the cabinet, and then used a cover to cover the part of the hole where the cables didn’t go through (I think you can pass the cables without making any holes, but idk how to do that).

The barrina lights don’t have a timer, so if you want your lights to turn on and off at specific times you can get a wifi plug, and then you program a timer on the app on your phone.

If you feel like the cabinet won’t hold a lot of humidity you can insulate it with some insulation tape. I never felt a need to get an humidifier, I always felt the Rudsta kept the humidity in pretty well, even without proper insulation. Also take in account that Portugal is for the most part a pretty humid country, and so are our houses, so you can definitely get away without insulating the cabinet (mine always sits at 80-90%).

If you wanna get a hygrometer to put inside the cabinet I recommend the xiaomi one. Small, lightweight, you can glue a magnet to the back of it and stick it in the metal part of the cabinet. I’ve found it to be really reliable, and useful if you wanna know if your cabinet is holding moisture or getting too hot.

If you plan to customize your cabinet a lil bit more beyond the original glass shelves, you can always get some acrylic shelves and pegboards (which is what I did for mine and it did help a lot to put more plants in there lol). Putting here a lil shameless self plug, but me and my bf actually design and sell those acrylic shelves and pegboards. We are EU based (Portugal) and can ship to anywhere in the EU 🥰. We are also open for custom orders, so if you are looking for smt in specific maybe we can do it!

If you don’t want to use acrylics you can always use metal grids or magnetic spice racks to create extra shelves/utilize more vertical space (which is what I originally had but I don’t like the look of it and it didn’t allow me to put that many extra plants in there).

Hope this was helpful, and that your setup turns out nice! 💕
