Tomato plant care advice.

[fiskies]

My early toms are about 3 inches in height now all in individual 3" pots. I put them out in my blow away today as it was measuring 25degrees in there at 10am this morning, they've spent all their time on a sunny windowsill since this. My question is is this too hot a jump for the day time and should I perhaps leave it a while before they are bigger. They are destined to live in the blow away someday. At what stage do I then plant them into their final pots in the blow away which are 45cm wide.

25degrees? Room for any more in there haha

Here's two pictures if helps with the advice, cheers.

I don't think a hot day will be a problem, if the temperature is up the sun will be out, so they will get all the light they need and the temperature will encourage them to grow. In a few weeks a blow-away will be needing some ventilation on a nice sunny day otherwise it will be over 30C

Tomatoes need to be 10C or more at night though (and during the day when it is not sunny )... otherwise the will stall and then take a while to get going again. But if you can bring easily bring them in for the night I reckon you are onto a winner

My GH was at the same temp today but left my tom seedlings aon the window sill in the house. I have heard somewhere (brain fade) that wildly fluctuating temps are a bad thing.

I don't think the temperature going up from 10C to 20C will be a problem (and it will happen over an hour or two in the greenhouse). However, I don't think temperatures much above 20C will be all that good for them - so some ventilation needed above 20C

Tomatoes need to be 10C or more at night though

That's the basic rule, right there.
Don't be fooled by Thermometer-In-The-Sun readings

Your thermom should be in the shade anyway, to give accurate readings

I was told by an old gardener not to transplant them to the final growing place until the first flowers have arrived

That's my rule of thumb too.

What about those I plan on keeping in the blowaway will they fare any better if transpalnted a little earlier?

[Davyburns]

I think the flower rule applies to all
