Light
Super....Hope your trial goes with few errors....
Hopefully thats not a mercury vapor 400w,,you will have trouble growing(wrong spectrum..high radiation) especially with hydro..... I believe BPP has a link for low cost hid ...good luck ![]()

7-10 is fine, depends on amount of fluid, less water (like a gallon or 2) 7-10 days fine. If your reservoir is bigger (4 to 5 gallons) you can stretch it out longer, like 10 to 14 days. Just keep an eye on the EC and when it starts to peak and you have to start adding plain tap, no nutes every day. Time to change. Here's a spare hint: Expect to see pH rise early on on the cycle, veg through early flower. You almost always grab for pH down every time. Then later on when she is really flowering, the water almost always goes acidic and you have to add pH up to get the reservoir back to the standard range.

zig864...mulli
If the MV bulb you are using is phosphor coated(white)it will still grow(slow and inefficient)but it will grow..until you can provide an alternate....but hurry..keep a good distance from the bulb...(high radiation output)
Also,, depending on ballast type,wattage....there may be an alternative to buying a new ballast ,,, by replacing bulb with a Multivapor,or Metalarc bulb..which are halide type bulbs.. ![]()

The bulb has got a white coating. It's a lamp looking thing, it was orginally from an industrial site. They must been doin' a bit of work at night.
Anyway I got the MV 400w info from a sticker on the ballast. I have no idea what globe is in the actual lamp, there is no writing on it at all. So I assumed from the info on the sticker that it was that type of light!! I do have another ballast....somewhere. Actually I'll go and suss it out.....hang on....I'll be back... |
