Like others succulents, this blue Agave plant doesn't require a lot of water. It's actually native to arid regions, so it's adapted to survive in drier conditions. When it comes to watering, it's important to find the right balance. 

You should water your drought-tolerant Agave Blue Glow thoroughly, but make sure to let the soil completely dry out between waterings. Overwatering can cause root rot, so it's preferable to underwater rather than overwater. 

In the summer months, during the growing season, you can water your blue glow agave every 2-3 weeks. In the winter, when it's dormant, you can reduce the frequency to once a month or even less. 

Remember to always check the soil moisture before watering. Stick your finger about an inch into the soil; if it feels dry, it's time to water. Also, make sure the pot has good drainage to prevent water from sitting at the bottom.  

If you are growing your Agave indoors, it prefers bright, indirect light. Place it near a window where it can receive plenty of sunlight, but make sure to protect it from direct, harsh sunlight, as it can scorch the leaves. If you notice the leaves stretching or leaning towards the light source, it's a sign that it needs more light. You can also supplement this glowing agave light needs with a grow light if necessary. 

When growing outdoors, this blue Agave grows well in full sun exposure to light shade. It loves basking in the sunlight and can tolerate high temperatures. However, if you live in an area with scorching hot summers, it's a good idea to provide some afternoon shade to protect it from intense heat. Just make sure it still gets a few hours of direct sunlight each day to maintain its vibrant yellow edge. 

Remember this is a versatile plant and can adapt to different light conditions, but it generally prefers bright light. Just keep an eye on how it responds to its current location and adjust accordingly.
