You usually dont give them nutes if your in soil for 2-3 weeks. Usually just 2. But ph balance your water to 6.5. Also if you do use nutes, just 1/4 strength of the dosage recomended on the label.

As for the 250 watt, it will hold out for 3 plants, 2 would be better yield. If you get some cfls to supplement you could do 3.

It's enough light for 3 small plants. If you want to grow small indicas and use about 3' total of that 10' height and only 2.5sf of floor space then that's ok.

If you are wanting to use the whole space and grow as big as you can or tall sativas you'll need more. You'll also need good ventilation and a cooltube.

I suggest something like this:

Or better yet, there's this:

Yes you could use 600w in that space.

In addition to the above you'll need some ducting, and a duct fan

No nutes for the first week or two, wait for some full leaves, then 1/4 strength nutrients and work up from there if there's no sign of burn.

thank you for the posts
