Hey I got some plants in a closet growing under a ten dollar grow light i bought from walmart, i saw it thtere and it was so cheap so I picked it up. Anyway the plants have came up, but I was wondering the house its in has central heating and cooling at the house is somehwere between 70 -75 degrees all day, in the closet i have the light, 3 plants under the light, and a fan pointing on the plants. Anyway theres really no ventilation, the central airt and the fan, the door to the closet is open sometimes closed sometimes, anyway are they gonna be alright? Do they have to be open to the inside.
the ventilation issue sounds okay. I would get more lights if you intend to produce any bud. Mini-spiral CFL bulbs are awesome (IMO). Relatively cheap, easy to use (they screw into a standard light socket) and run fairly cool (compared to incandescent bulbs).
