Im keen to start a second grow and know this time lighting is key. After using cfls its time to upgrade. With this particular model QB is it perfect for achieving big buds. Are these ideal for a number of plants at one time or just one. Any help in deciding a perfect led light for round two would be mint HLG 300 Quantum Board LED Grow Light (Dimmable) 285 Watt Draw - Quick Bloom Lights
That light is great for a 3x3. Get the 3000K for flower and veg. @Tbone Shuffle will be able to tell you more about the combinations.
That is their more expensive fixture. I’d rather use two of their 135 watt kits or 4 120s or 132s. But I see your in AU so I am not sure what you can get your hands on.
