Hi ..Once again thanks for your wonderful replies...Last night I cleaned the four HPS 250W housings ...I found only two with bulbs ...one bulb that looks alright and another that the E40 turns and white powder is escaping so I presume it has had it...I have already imported 4 New bulbs .....So these will be wired later today and put up ......I was doing some reading also last night and I wonder if I can get my "growroom" more light efficient..

I have 2 x 400W fittings which I understand are for Metal Halide bulbs and I have a lot of fittings/enclosures and the bulbs for 80W Mercury Vapour lights......The HPS at 2100K I know will help my tomatoes Ripen but I feel I might require some bright light IE round 6500K and am wondering if either the Metal Halide and Mercury vapour lights would be any good for this......

I also have a number of ordinary Flouro 5 foot tubes PLUS I have some LED five foot tubes and I have a 6 plus 1 E27 bulb fitting on its way from Newfrog?? so I could put up to 7 CFL bulbs in it .. I have tried to cover my bases for light but of course do not have the required knowledge on how best to employ these....I do understand the kelvin temperature I think?? My plants are now producing very small tomatoes So thats a relief.....Hopefully I am going to get a few years of enjoyment and all year round tomatoes for my effort....Yes it has cost money but at my age achievement is more important...Regards Ron
