You can also use a special sprouting bag instead of the original jar. Place the sprouting seeds into the sprouting bag and hang it over a sink or other area to allow draining. Continue to rinse every five hours or so.
Keep in mind that sunflowers planted in pots will not grow as big as sunflowers planted in the ground. Sunflowers are drought-tolerant, but you should ensure they get plenty of water while they establish their roots. They can also survive in wet, humid weather, but you will need to make sure they are planted in well-draining soil, like a sand or loam mixture. [2] X Research source
