halogen do well in flowering , i have a freind who done a ghetto grow with flurecent tubing for veg and 4x 500watt halogen for flowering he grew 10 nebula seeds and hic yeid was exellent , the only prob with halogen is heat but if you have the space with enough ventilation they do ok but the are not as good as hps , no where near it but if financies are low and you have the space they do the job, cause we are talking £5 to£10 for a 500 watt and thats pennies to grow a good smoke
