For now you have enough light but in soon future that wont be enough !
You have a large closet . What are dimensions ?

For that space a 400 w hps would be great ! She have around 45000 lumen's ! You need at least 25000 lumen's per sq/m !

You can grow your plants with less then 25000 lumen's but they will be poor !

Ventilation => try to put a exhaust fan in the closet because when you go on 12/12 the closet must be light proof . Thats mean that your door must be closed !

For now you must install more light !
DreamerGirl7 Reviewed by DreamerGirl7 on . 1st grow! Check it out!! Here's my set up so far. I will remove the shelf when the plants get bigger, but for now I'm using it as a "nursery." Total Lumens is close to 1,000 all CFL (24hr on). The temp stays around 75-80F. The large fan is for added circulation/cooling. The soil is a local mix (Okolona Mix) with added perlite. The pH is around 6.8. These plants are 2-3 weeks old. What do you think? Suggestions, criticisms, advice is always wanted and appreciated! Rating: 5
