Greenhouse only effecting certain blocks

[arielessar]

I have this hobbit like green house that's 7x7. The roof is laid out like below (where g is glass, and w is wood with a little dirt on top.) nothing is blocking the glass and its above 50% of the roof.

g g g g g g g

g g g w g g g

w w w w w w w

w w w w w w w

w w w w w w w

g g g w g g g

g g g g g g g

Now the weird part is that, the game registers some of it as a greenhouse. Is there like a period where it slowly effects every block after building? or should all the blocks update at once?

According to the wiki, the game only checks every 4 in game hours +  a few seconds. If you made your farm tiles after making the green house it may not have updated them all at the same time. Waiting should fix the issue.
