impsvi Posted June 17, 2002 Share Posted June 17, 2002 if growing indoors you will need a high intencity discharge lamp (HID) these come in HPS (high pressure soduim) or MH (metal hallide) form, i recomend a son-t-agro light bulb to fit onto one of these hid lamps. When plants are young and in vegitive stage they should be getting at least 18 hours of light a day. When plants are flowing the light should be on 12 hours a day and off for 12 hours a day. Plants only need a lilttle water. Saturate the soil with water and when the soil drys out (should take some time) water agian. Beware its very easy to over water cannabis. Best day temp is between 25-30c at night between 20-27c but as long as the night temp doesnt go below 0c and at day time it doesnt get hotter than 34c it should grow!
