How do these lamps compare to switching lamps for the flowering stage? also any UK based growers have a lumatek 1000w digital ballast? my research suggests they have not been released in the UK? Regards
im useing a dual spectrum 600w bulb now because my plants will get the full spectrum all the way throu their life like the sun gives them the sun don't give them 6500k fore veg then thinks its time fore cannabis plants to flower now so ill give it 2700k. no it don't it has the full spectrum all the way so imo it makes sense to use a full spectrum bulb all the way. watch this video all the way through befor you reply because it MIGHT change your opinion on dule spectrum bulbs if you dont like them [ame=http://www.youtube.com/watch?v=5zgq7JGHTqI]YouTube - 1000w vs 600w Trees Yield.mpg[/ame] lumatek 1000w digital ballast i dont think its still not been releast in the uk yet iv had a look my self brov
i use the sun master bulb its brill but iv not got a digital ballast yet but i will get one wen i can afford it cos they give you 5-10 more lumens 600w HPS SUNMASTER DUAL SPECTRUM BULB / LAMP HYDROPONIC on eBay (end time 02-Feb-11 16:40:24 GMT)
I'm running duel 600w lumateks, during veg I rock one red one blue, then when I flower I switch to double reds. Then the last two weeks I rock the two blues.. Get buds as big as my arm
I use both HPS and MH thru my entire grow. The MH is critical for producing essential oils and flavors later in flowering.
