We sent a WhatsApp message to our customers about our discounts and promotions, hoping that our customers would know about our events. The customer replied that there is an experimental project now, and they want to plant green leafy vegetables. The site is about 40*15*3.5 square meters, using the NFT system or hydroponic towers, but the customer is not sure to pay attention, because this is a company project. We suggest to make two plans for the customer's reference. After the customer agrees, we are now discussing the plan with the customer.
