Planting carrots now?

Hey, I'm a complete newbie when it comes to growing anything. So please forgive my ignorance. Is it ok to plant carrots in a greenhouse now? Currently early July. Also, can I plant garlic and potatoes? Will they grow or do I need to wait? Many thanks in advance

By the way. I live in the south east, near Ipswich.

 

I am sure many more experienced than myself will give you good advice.
In my limited experience, baby carrots will grow quite fast. Rocket too.
Potatoes, if you select the right varieties, can be planted all through the Summer, but they do take time to mature.
I undestand people will plant them in August for a Christmas crop

My advice, as someone who started growing only last Summer, is to research varieties of vegetables and plants which might benefit from a very early start in preparation for next year, along with things which might actually manage to grow even this late.

As you know, it is way to late for many classic crops, such as tomatoes, courgettes, cucumbers and so forth.
If you plant strawberries now, you might get good deals on plants and bare roots for instance, but few if any strawberries this summer. But it still makes sense to plant them, because by next summer they will be very well established, and therefore more productive than if planted in early 2020. You might also get shoots, which you can plant and make new plants for free.
A number of vegetables can be planted as plugs (tiny plants) purchased from garden centers and onlne (Sutton's are discounting some Half Price Veg And Herbs - Half Price Sale - View all Offers - Gardening - Suttons which might grow ok this summer).
Spinach varieties such as Gigante d'Inverno can be planted in late summer or even Autumn.
Blackberries, citruses and other plants can benefit from an early start now, to make them productive next year.

When I started I was disappointed how much more I could have planted if I began in early Spring, instead than early Summer. But then I realized that one can start planning in advance for the next year, which is not as exciting of course, but does pay back big time.
Same for preparing raised beds, self watering pots and similar. It pays back having them ready for the following year and it makes it more likely to find the actual time to actually plant things on time.

This is a pretty good site I was directed to recently, and you can set a planner to remind you when to plant too GrowVeg.com - GrowGuide Plant Index

Happy growing

 

Not sure I would sow and grow carrots in a gh robolist
Best outside and you could still get a crop.
