the only way i would flower with that is if i flowered clones right after they rooted. its a good light but the penetration is less than an HID would be.

the reason i wouldnt flower at 10 inches is because there is a great chance the plant is not fully mature to throw into flower...resulting in a longer flowering time and a taller plant.
but thats my opinion, i have been interested in a t5 for a long time now, whatever you plan on doing, i would be interested in the results with the light.
keeko Reviewed by keeko on . ? on lighting indoor grow Hi, I am new to the whole grow scene so I have no idea of what I am doing. Would a 2' 8 tube t5 unit be big enough for 4 small plants? I would flower them at about 10" so they stay small. If I flower at 10" how tall would the plants get when ready to harvest? Maybe 24"? Rating: 5
