yeah, what crispi said. it isnt the first 2 wks that stretch your plants its the light change(mh to hps). it will do it anyways. mh will actually stretch more because its not really the spectrum for flowering.
twoguysupnorth Reviewed by twoguysupnorth on . blue for flowering stop streaching!!!!! when clones go from veg to flower they streach the first week or two. So can i use a mh or maybe cfls 6500k for the first 2 weeks then switch to hps. will this stop the height and will this have a negitive on the bud set or # of budding sites Rating: 5
