Why would the growth be slower? If anything they will grow faster with those lamps. Use them they'll be great.i have a mini grow goin just 2 girls, i have 2 75w hps lights will these be ok for the girls to veg? i know the growthrate will be alot slower....will it be much of a difference?
What your using for veg now is fine, But if you want faster growth Then IMO use the HPS. I Put my vegging plants in my flower room during day period just so they can get a bit of faster growth rate.Man thats more then what im using for m y veg process!!! Im using 6 clf's that equal to 104 watts!!! And its for 7 ladies!! I ahve a 600 watt hps that i wanna use but ppl say that what i have for veg is fine???? I dunno!!
