Another established hardware startup is turning to Kickstarter to help fund its next wares. This time it’s the turn of Click & Grow, maker of the smart garden that lets you grow a plant indoors with little or no intervention. After selling over 50,000 units of its first device, the Palo Alto, U.S. registered company with an R&D lab in Estonia, is launching a crowdfunding campaign to get its second generation product – the Smart Herb Garden – off the ground.
