Best Bulbs for Ben B
I love the UV and extra trichomes! LED does not make sense for us yet and these bulbs make CMH really inexpensive. We run them with generic square wave digital ballasts and they are perfect. You only need to change the bulbs every 12 months in 12 on/12 off flower. Ask for the buy 4 get 1 free promo! We got a couple extra bulbs that way for spares with our last order (bought 8 got 2 free! Hell yeah Vivagrow!)

Glad I switched to cultilux
I've had experience with other lamps but these have exceeded my expectations! Excellent customer service too!

Super value
Got the discount deal with a free bulb. Came out to less than half of the price of the bulbs we were using which are USHIO 315's. Next we are gonna mix the 4000k with 3000k and see what happens in flower.

UV for me
If you want trichomes get these cultilux bulbs

Bright boy
We have 10kw indoors, switching to more cultilux 315s over time while our bulbs wear out. Vivagrow supports these bulbs no problems

Tent lights
Way better than 600 watt HPS in a tent, these bulbs run cooler and we are getting more yield.

Awesome bulbs awesome price
These bulbs are the best I have ever used growing indoors. That includes Hortilux and Philips. These are half price or less! The extra UV really helps develop more trichomes and the plants just look better all around.
