slow growing of seeds

[moria0672]

This is my grow box


I've problems with it because seeds are very slow to germinate (more than two months to see some movement).
I'm sure that's not a temp. problem (is fixed at 26°C) and 2 PC fans moves the air to uniform the temperature into the box
Light is switched on for 12 hours a day and are a saving lamp of 11W (like a 75W incadescence lamp) and a fluorescent tube of 18W with 10.000 °K.
The growing media are P669 and W2.5 from OSP. I'm happy because at the moment I've no contamination in the flasks but nothig happens.
What's wrong????
Maybe the light??
Please help me understand wher's the mistake.
Thanks
