tomato husbandry

[stanley]

Could anybody tell a 1st time home veg grower how much ventilation should tomato plants get during the day.I have a plastic greenhouse with a 60lt growbag with 3 plants in it.All 3 plants seem fine 1ft high with signs of tiny flowers appearing.Two 'shirleys' and 1 'gardeners delight'.As you can tell by the details,a novice has posted this but i've been bitten by the bug and can do with the advice. Cheers!

I open windows/panels equivalent to an area at least a third of the floor area of the whole greenhouse - more if it's hot, don't know why, must of read it somewhere!

I ventilate as much as possible during the day, but make sure it's closed up at night.

Mine are in my lean-to which is south facing and gets very hot during the day. My rule is if I am in I have the window & door open unless its raining. Always closed at night

As the others say, give as much ventilation as possible during the day unless there's a howling gale. ventilation allows pollinating insects into the greenhouse and helps prevent some disease problems.

If you've got steam and/or condensation inside your greenhouse: you need to ventilate
