The best way to keep your house cool naturally without air conditioning is, of course, indoor plants. We recommend you keep air-purifying, oxygen enriching plants like aloe vera, areca palm tree, snake plant and golden pothos at every possible nook-and-corner of your house. Since these plants are not easy to find, you can get them from Rise N’ Shine Botanical Boutique at Koregaon Park. This garden nursery has everything from orchids to bonsai and more.
