You need a powerful light to grow things underground. Many plants require light level of 14.

I think you could use mese lamps (is that it's name?)

I just checked and mese lamps will work. Just remember that the light level drops as you get further away from the light. You will need a lamp every 3 or 4 nodes for many plants.

if mese lamps have max.light, wich is 14.
if plants require min light 14, they must grow directly next to the mese lamp.

# - mese lamp; O - grow; X - no grow

XXXOXXX
XOO#OOX
O#OOO#O
XOO#OOX
XXXOXXX

according to this, you need 1 mese lamp every 4th node and alter the pattern by 2 nodes in neighbouring rows.

XXOXXOXX
XO#OO#OX
XXOXXOXX
XXOXXOXX
XO#OO#OX
XXOXXOXX

or if you use this pattern you can grow 1 more plant for the same number of mese lamps, but you will need more space to build like this.

the light level of lighting nodes decreases by 1 with each block distance.
in your current set-up, the place above the mese lamp would have enough light, but the place next to them doesn't.
you need to put the lamps on the same height as the wheat.
also torches are not bright enough for crops, they can only cover dirt with grass.

you can also put the water below the dirt, it will still turn wet.
this way you can save space and fully utilize the mese lamps.
(only the 4 adjacent nodes get enough light to grow plants.)

great :D
now, if you move one of the lamps 1 node to the right, you can grow 8 wheat plants instead of 7.
(see my previously posted patterns for reference.)

You should be able to grow in the diagonal nodes too.
