most T5ho lamp u can get in the market are for aquarium use. There are dieferent spectrum for diferent needs/requirements. Being at 6500k, the light wil look like day light and look a bit yellowish. 10,000k less yellowish, 14,000k not yellowish and has little blue tint. 20,000k wil be very white and look blueish. wat i mean i put a 6500k + another 20,000k, i mean 2 lamps runing same time.. remember to keep your plants 1 feet from lamp at least. you may need to add lamp reflector to improve efficiency of your t5ho lamp. there are nice T5HO reflector selling at >rm50 too.....
