I managed to get a hold of Hydrangea seeds but haven't come round to planting them as i am not sure whether they will survive in my garden or as potted plants indoors.
We are almost going into a rainy season where it rains non-stop and the ground is usually soggy and wet for a long time but when it shines, it shines till all the grass is brown and dead (Tropics) Which is the best way to grow them?

Grayc, welcome to ATP!

This is not an absolute answer, as I have never gardened anywhere but Ohio... But, I can tell you that my mophead hydrangeas don't tolerate heat very well. They wilt and whine when sun hits them, and cry for water. If they're adequately hydrated they perk up after sunset. They don't tolerate hot afternoon sun well.

I'd try them in the ground, as I think the roots would be cooler and the plant happier. They don't tolerate hot afternoon sun well, even in Ohio.

You'll have better luck starting the seeds in small pots, Grayc. This way you can regulate their water/soil moisture needs easier. Once the seeds are up and get several true leaves you can move them to individual pots which are a little bigger. They grow pretty fast so it shouldn't take long. Depending on the rate of growth you should have plants big enough to set in the ground at around 3 months.

And definitely plant them in the shade as most hydrangeas prefer it.

Depending on which kind you have your seeds will germinate in as little as 10-14 days or take as long at several months. Any idea which ones you have?

Hope this helps!

Paniculata is a good, hearty Hydrangea so you should have good success with it. There are quite a few cultivars of it so who knows which one you'll get from your seeds. And by the way, if your seeds are fertile they should germinate in a matter of a few weeks, not the several months I mentioned above. If you have access to adult plants you may have quicker success, and just as much fun, taking some cuttings and rooting them...rooting hydrangea is about the closest I can come to describing "instant gratification in the world of plant propagation".

Welcome to the site, Grayc. Hope to see you around!
