For instance, before the Phoenix Flower seeds are buried in the soil, they need to go through four high-temperature processes, and the requirements are very high.
Plant Mages can rent one of the high-temperature devices online here – it's a cubic foot in size, but the price is very high. Then they come over to operate it themselves for about half an hour each day. After ten days, the flower seeds are well-cultivated and they can take them home.
Do not underestimate such a high-temperature device; its price is very expensive, and some high-level Plant Mages do not even have one at home.
The cultivation of Flower Face Mushrooms initially requires an anaerobic environment. Where could lower to mid-level Plant Mages have such equipment at home? They come to this botanical garden and rent a small cubicle in the cultivation center.
Similar facilities also exist in the breeding gardens. As one can imagine, this training center will be very popular once it is built.
