hey everyone im completely new to all of this and need some serious help! right now i have 5 small stems that have been growing fine untill now. my setup is a small box lined with white wrapping paper on three sides and then one side is covered with dull aluminum foil. the lighting that i have up is a 150 hps that is about 2 ft away from the plants. i have a fan blowing directly on the plants to help with the heat issue because it is getting up to almost 100 degrees in there. it is an open top box thats inside my closet. the plants are about 5 inches tall but i havent seen any new growth in about a week now. all of them have 2 oval leaves and 2 pointy ones. i need some serious help! i am trying to do this as cheap as possible. PLEASE HELP :/
