Advice please

Greetings world,
I have a small closet, want to grow two plants. The light I am using is a Mini Sunburst Sodium 150 watt grow light. In addition to this what else do I need. The walls are covered in tin foil. What do you recommend for fertilizer, I have been using Botanicare power plant. One last question, I need quality seeds but very hesitant to use my credit card to buy online. Has anyone ever had a problem with the law buying seeds on line? I know it may be risky, but it is my only choice.
Thank you all for your guidance.

In Uk it isnt illegal to buy seeds for souvenir purposes only illegal to pop them in water

ps ive bought on CC 3 times but i buy a few at a time so maybe i buy once a year.........but like i say in UK not illegal to buy only illegal to pop.....not sure where u r.............

Have ordered about 20n times from the attitude and all made it to me in the good ole USA...

Happy and safe growing.

i wouldnt use tin foil it can cause hot spots on plant leaves and burn them. especially with hps lighting. id either use mylar or paint the walls white. white paint reflects better then tinfoil anyway so ive heard.
a lot of people order from seed banks, very few have problems regardless of where they live.

Thanks guys, but what about my set up.... It the light sufficient ?

Very cool, lucky me the walls are white down comes the tin foil.

Should be,But might do better with one plant though.
