It then compares that against the known light requirements for your chosen plant category and tells you clearly whether natural light is enough, marginal, or insufficient. The logic is calibrated for 59\u00b0N latitude, where winter light levels are dramatically lower than most guides assume.<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>This tool answers:<\/strong><\/p>\n\n<ul class=\"wp-block-list\">\n<li>Does my south, east, west, or north window provide enough light for what I want to grow?<\/li>\n\n\n\n<li>How much does distance from the window actually affect my plants?<\/li>\n\n\n\n<li>Can I grow herbs or fruiting crops through a northern European winter without artificial light?<\/li>\n\n\n\n<li>If I do need a grow light, what kind should I be looking for?<\/li>\n<\/ul>\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n<h2 class=\"wp-block-heading\">DLI Calculator<\/h2>\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"649\" height=\"208\" src=\"https:\/\/indoorgarden.ee\/wp-content\/uploads\/2026\/03\/pilt-3.png\" alt=\"\" class=\"wp-image-5014\" srcset=\"https:\/\/indoorgarden.ee\/wp-content\/uploads\/2026\/03\/pilt-3.png 649w, https:\/\/indoorgarden.ee\/wp-content\/uploads\/2026\/03\/pilt-3-360x115.png 360w, https:\/\/indoorgarden.ee\/wp-content\/uploads\/2026\/03\/pilt-3-300x96.png 300w, https:\/\/indoorgarden.ee\/wp-content\/uploads\/2026\/03\/pilt-3-600x192.png 600w\" sizes=\"auto, (max-width: 649px) 100vw, 649px\" \/><\/figure>\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/indoorgarden.ee\/tools\/dli-calculator\">Open the calculator<\/a><\/div>\n\n\n\n<div class=\"wp-block-button is-style-outline is-style-outline--2\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/indoorgarden.ee\/et\/varia\/mis-on-dli-ja-kui-palju-valgust-su-toataimed-pariselt-vajavad\/\">Read the full guide<\/a><\/div>\n<\/div>\n\n<p class=\"wp-block-paragraph\">DLI \u2014 Daily Light Integral \u2014 is the total amount of photosynthetically useful light a plant surface receives in a day, measured in mol\/m\u00b2\/day.
