Mh Bulb question.....10k, 4k, or one of each?

[wpg_breeder]

my pal who owns one of the many hydro shops around town gave me the option on 10k spectrum and 4k spectrum should i get one of each for my cool tubes or stick with 2-10k or vise-versa?

4k but if you have access 5500k or 6500k imo.

 

[wpg_breeder]

its for the limitek digital 600w and it going in the cool tube i have to choose 4k, 10k, or both

 

[BombBP]

I'd go with 4k. I have heard you can use a 10k the last week of flowering to bring out colors but i've never tried it myself.

 

[sdgrower]

BombBP is correct. You only use the 10k bulb during the last week of flowering.
4k=veg
6k=flowering
10k=ripening/resin production

The sunpulse bulbs are great!!!

Come in these kalvin ratings

3k, 4k, 6.4k, 10k, 14k & 20k

I use the 3 k for flower and 10 k for last 2 weeks.

10k bulbs tend to flicker and also the 4k's but seem to have no bad effect. Infact I think these bulbs are excellent. Better than HPS ime. Bloody expensive tho. But I won't use anything else these days.
