Himalaya Gold - suggestions, advices & etc.

Hello there, i was completely forgot about 5pcs of feminised HG seed!
Now i'm thinking about indoor project, but i'm really curious about that what type of bulbs is alright to use, because i have only one 1000w. The other problem is that i can't decide where exactly to put the plants. So any ideas what's the smallest spot where i can put 5 HG plants? Also i want to know what are the most iconomic bulbs, i don'to know, maybe LED? I'm ok with the fertilizers & etc. but really wondering what type of lights will be the most felicitous and inexpensive way to do it right.
