Add weatherstripping around doors\/lids; tape seams to eliminate light leaks. <\/li>\n\n\n\n<li>Place on a stable, dry surface near a GFCI outlet.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Tip:<\/strong> <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Do a dark\u2011room test: turn on the light inside and look for leaks; seal any pinholes with tape. <\/li>\n\n\n\n<li>If using a bin, cut a hinged access flap for easy maintenance.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">2. Line the Interior with Reflective Material <\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Reflective material helps to maximize the light distribution within the grow box, ensuring that your plants receive an even supply of light. <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Apply mylar or reflective insulation to all interior surfaces (walls\/door\/ceiling). <\/li>\n\n\n\n<li>Smooth out wrinkles for consistent light distribution; secure edges with foil tape.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Alternative option:<\/strong> If you don\u2019t have mylar sheets, aluminum foil can be used, though it\u2019s less effective.

Set Up the Light Schedule (typical): Ventilation System <\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Good airflow is essential for maintaining a healthy environment inside your grow box. Without proper ventilation, plants may suffer from mold growth or poor air circulation, which can hinder growth.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Create low intake and high exhaust to promote vertical airflow.<\/li>\n\n\n\n<li>Budget: 80\u2013120 mm PC fan intake + PC fan exhaust<\/li>\n\n\n\n<li>Better: 4 in inline exhaust fan + carbon filter; passive intake (vent or gap)<\/li>\n\n\n\n<li>Size fans by volume: CFM \u2248 1\u20132\u00d7 box volume (L\u00d7W\u00d7H in ft\u00b3).
