Yes. Let's say it's a candle spell. On the first day you would charge it with energy, and light it, visualize and let it burn 1/3 of the way down then snuff out the flame. The second night [roughly the same time] you would put more energy into the candle, light it, visualize and snuff it out when it's burned down another 1/3 of the way. Day three you would charge, light, visualize and let the candle burn down completely. This way you've put a lot of energy into the spell. It's also believed you should end the spell on the full moon since the moon will be at its strongest. [If it was sending something away like a curse you would try to finish the spell on the new moon for the same effect] of course this all depends if you believe in moon phases effecting spells.
Generally falling under affirmation, candle/lamp magic, or a work which is continually worked (i.e. poppets, jars, sachets, etc.).
In the case of candles, as above, you generally work one (set of) candle(s) for that particular work. It is beneficial to allow a work to manifest instead of doing a 'ritual' over and over to accomplish a single goal. Lamps, on the other hand, you would continually add oil to and it would be one work, just worked continuously. You wouldn't have three lamps going, unless they were covering different aspects of a situation.
Poppets, sachets, jars, and affirmations fall under the same aspect of lamps, they are crafted and worked until the work has been accomplished. Affirmations work on a more subtle level, but they work towards as a goal, as the others.
Now, to confront the idea of 'triple casting'. It can be undermining, especially, if done out of doubt in your tools and ability. Allow your working time to manifest, otherwise, you can impede yourself. Have confidence!
