I transplanted my girl into a 13-liter grow bag. I surrounded the bag with lots of dried seaweed (as thermal isolation) so that it doesn't get heated by the sun too much and doesn't cool down too much by morning.
Long before the planting, I drenched the soil with water and added some mycorrhizal powder and left it all cook for a few days. Hope it helps.
For the whole of the second week, I didn't have to water my plant once.
