Sorry, never used a hortilux light so don't know much about it. Use NPK fert with high conc of P for flowering. Use no more than recomended amounts on packet, I find it works better to give half the recommended strength twice as often, If your growing hydro, I don't know (I grow soil only). To flush, put your plants in the bath and turn the shower on warm/cool. Flush water through the soil untill liquid coming out of the bottom is almost clear, hence the name 'flushing'. Hope I've helped
amstron Reviewed by amstron on . How far do you want the light during flower, and do you give the same amount of nutes I have a 400 watt hortilux, and was wondering how far to keep the light from the buds during flower. It has a hood with a glass cover and one of the buds is touching the glass. It's not hot at all (the glass), but it looks like the lower buds have more crystals. Also, do you give same amount of nutes you were giving during veg? Last question, I water probably every 4 days, do you reccomend flushing? And if so, when and how do you flush?
