Is my tent to small for vertical grow?

tHey there

I'm just approaching the end of my first grow.

really excited about starting my next one, iv been on a tight budget and feel that my second grow will be much better.

I currently have 4 plants in an 80x80x160 tent. I'm using cfl's.... I have 1x 300 wat under a reflector above the plants and I have a 105 watt CFL hanging vertically between which has bade a huge difference.
for my next grow I will be purchasing a dimmable ballast and a cool tube.

is it possible to tun a cool tube vertically with any reflective part removed so its 360 light... If so... Would my tent be to small so that the plants will be to close o the tube?

I'm looking at many different ideas... So open to suggestion.

I'm also toying with the ide of just running 2 plants but mainlining etc to make 2 big plans as appose to 4 plants.

I'm also thinking about a kind of vertical scrog net that could surround the light.... If this doesn't seen a possibility then ill just go with tour standard scrog for this grow.

there are so many options and I wanna make the mist of the small space I have.

id appreciate any help/ ideas you may have. I'm open minded and all ears right now lol

thanks in advance for any comment

peace

2 plants will work fine, but you can grow 4 - seems that you might need more light for such a large tent. but add more side lighting 3 more for 2 plants and (4 total) and 8 for 4 plants - you do know that sidelighting can increase yields by 50% + Many use 500 watters only $25.00 - - bit 105's will work MORE LIGHT = MORE BUDS Why not LST - must look at your lighting suitation; easier tho -vertical srog knowing wrong with that -- they tend to take extra time/issues
