a kitchen fan , rated for continuos use can be had for less than £100, ducting tube is cheap add a few clips etc and a suitable hole to outside
lettuce probably do not need an activated carbon filter rig so even a small fan should do a domestic room
if lettuce do need a filter(spray booth kit is good value)a decent 6" fan should do the job against the back pressure so long as the ducting is short and tidy.
either way, getting the transpiration water out of the premises is required for plants, house and persons to stay healthy.
i am sans luminaire at the mo but the newish led stuff looks ace
go for decent kit, the amateur stuff is carp
ps re ventilation you might need a couple of circulation fans to stir the air about as well as extraction
if the incoming air is from the house the extra co2 is ok but clean outside air from an in vent is pretty good
one can go the full high tech mars mission thing but gaffer tape etc along with very safe and simple design works pretty well

Um, I’ve been leaving the window open an inch.
I will discuss it with the plumber. I’m having the washing machine plumbed in there, and a sink for laundry. An extractor wouldn’t be a bad idea, as I dry the laundry in there, too.

We are threatened with frost or near frost over the next couple of nights, which is very late for us, so some of my seedlings will have to come indoors for a couple of nights. Luckily I haven't got round to planting out yet as I don't have any fleece.

In fact the major problem this morning is the wind. It is gusting and north easterly, so have given up any idea of work as it is too dangerous with the risk of falling trees and branches. Thinking about it, as it is only going to be a light frost, I could use an old sheet just overnight as I have plenty of metal hoops for netting.
