There's nothing worse than seeing a seedling you've been nurturing for weeks indoors get washed away by the first heavy rain. Tender transplants are also vulnerable to drying sun and cold winds early in the season. These oh-so-durable and generously sized cloches create the warm, humid and safe microclimate your seedlings need to grow big and strong. Four shallow reservoirs in each top collect rainwater and disperse it gently, drop by drop. An upper ring also rotates to create as much or as little ventilation as desired. Though they're pretty hefty, we recommend staking them into place with Earth Staples (sold separately) — especially in windy conditions.
