Avoid saturated media. Reduce mist as soon as possible. To reduce stretch, transplant on time. Apply preventative fungicide spray after sticking. Reduce mist as soon as possible. Scout regularly for Botrytis. Move rooted cuttings off mist quickly to avoid stretch. Ipomoea URC do not like to be stored, so stick immediately. Cooling cuttings can actually do damage, so it is recommended that, if you do store cuttings, do not put them in a cooler, and maintain temperatures at 55-60°F (13-16°C).
