Hey brother
When giving advice "Thinking something should be alright" is not a good idea, especially when the advice given isn't correct.
We all have the internet so please research before giving advice, seeds left in cold wet condition can kill of seeds, seeds which we pay good money for.
I applaud anyone who wants to lend a hand but please make sure your advice is good advice or you may ruin someone's day!
The ideal temperature is between 22° and 25° Celsius or 72F -77F and that will see your young ladies reaching for the light and growing big and strong. I personally use 24C and I keep it constant by using a thermostatically controlled heat pad/propagator.
