Veging monsters

Hi folks, I have a few plants, started with 4 now I have 9. all are in small pots and have been for months. I am moving and things went tits up so looking to keep them for months.

Question is, any tips to keeping them healthy under cfl and in smaller pots?

I was thinking training to grow vertical around cfls in cool tubes.... any ideas?

All in soil

Strain is Blue dream

I have a wardrobe I can use ideally use the height with 2 cool tubes.

extra soil will make extra insulation to keep cold away

best is 3 us gal pots under that then you come done with nute issue leaves

budget a gallon for each month they are with you

good luck
