and another question,
can I put 10 small pots under the T5 (4x18W) like for a week and then put them under HPS? that would be allrihgt?
sorry for silly questions, I'am new in this thing.

yea that would totally be alright.avoid putting them under HPS/Metal Halide bulbs until they are 2 weeks old.

but 10 plants under (4x18W) is alright? the light for the plants will be enough?

It honestly is all preference. Think of it this way.... Seedlings in nature aren't eased into strong sunlight and the sun is much more powerful (not sure the exact exponential difference than a 400w mh/hps) but i moved my seedlings under Mh (keeping it 3 feet away and bringing it down an inch every light cycle) after a week old and they seem to be loving it. Their greens are beautiful and i can already notice the stalks of the seeds getting beefier. If you do put them under HID invest in a few clip on fans or something of that sort, a thermometer/hydrometer with an external probe (i like to place it near the plants so i know what the temp is near their base) and last but not least a humidifier. If you are having problems with your humidity levels you can get a cheap one (relion cool mist humidifier 28$ at wallyworld) and i can not stress enough that you want a COOL MIST humidifier. Warm mist will throw your temperatures all out of wack.
But again when it comes straight down to the method you use its just personal choice. Have fun with your first grow and use it as a learning experience.

To add to something i left out... I did leave them under a t5 for a week before i moved them into the tent.

HID's ie. hps MH are hard on young plants they draw a ton of moisture out of the little ladies.....sometimes they can dry out and kill young plants that do not have sufficient root structure to keep up....so we place the babies further away than usual to protect them......BUT once you have moved them to a safe distance you loose much of the light's strenght.....so people use cfls, this way you can place the little ones dirrectly under them until the grow some legs that will help them run under an HID light. Also cool white cfls emit light in the blue spectrum, preffered by seedlings and vegetating plants.
good luck
