i need help on growing

[newgroweroldsmoker]

This is my very first grow, i used from start till a few days ago a 400 watt HPS grolux without any problems....within 5 weeks from seed i've grown 4 big ones (and 4 small ones due to my mistakes) into 2 footers grown in soil without any particular problems and almost no ferts.....now that i am into 3rd week of 12/12 i have added one more 400 watt HPS....i did some research and found this particular type of HPS which is called SHP-TS....that is designed especially for flowering....it is enahanced in orange and red spectrum....in other words does the same job with an MV/UVB lamp without having all the unpleasant side effects of using a UVB lamp (skin burns,loss of eyesight,skin cancer etc.).....as for growing veg. i came up to some new type of floros made by Sylvania...they're called GROLUX as well.....with four of those 4ft 44w each tubes you can cover an area of 12sqft only for veg....total of 176watts emitting the lumens of a 250 MH bulb....the total price for the floros is more than the MH but the operating cost is less,the distance from the plants is less, the heat emitted is less and the life of the bulbs is longer......

Damn man, you are right! The blue spectrum is closer to the ultraviolet spectrum than the red spectrum. For the saying, "You learn something new everyday", it is true! So, I personally would go with the MH. I would sacrifice quality for yield any day. Thanks man, thanks alot!

I take that back. A MH may produce more trichomes, but a HPS improves the quality of the THC.

I have a 400w switchable ballast, and for the money,$200 (including the cordset and tax) it is the bomb... to switch from HPS to MH all I have to do is change the bulb and flip a switch, NO conversion bulb expense, and they are pricey. MH is best for Veg, and in the last week of flower I use it for it's UV-B output, (more tricomes) HPS is best hands-down for weeks 1-7 or so of flowering.

Yeah, but they are worth it. When I get older, I will buy mw a 1000 watt hps/mh switchable ballast.

before you guys go out and buy new lighting systems check out the conversion bulbs at discount hydro (or anywhere grow lights are sold)...i've been using them for years (sunmaster) and both mh and hps conversion bulbs are easy to find and much cheaper than switching your ballasts.
btw, i use both mh and hps (1430W total) together during flowering. makes for larger, denser flowers.
