There is such thing as too much light, and this is especially true for young seedlings. However, you will probably be ok with just flouro's and cfl's. Even so, I use only a 21w flouro for the first week that the plants are above ground, after which I put them under my HID.

Yes a thermometer is very important... you will also need something to measure humidity. Something to measure ph and adjust ph is also a must.

Hoping you get some ladies:thumbsup:
