5th grow t5 or 600w hps veg

k_elliott99 · Jul 15, 2015

As the title states im in my 5th grow and I always use a 600w hps in my 4x8 veg room, bubble buckets, cyco nutes, I acquired a 2 foot 4 bulb t5. Im having heat issues so im considering using the t5 for veg. Also I figured also save on electric. Anyone wanna weigh in as to how much longer it take to veg under a t5 as opposed to 600w hps, pros and cons of each please, btw I flower under a lumatek 1000w and magnum xxl hood and pull 13+ off each plant

Spectrrum alone you would do better with the T5. HPS light spectrum is better for flowering, and MH or T5s are better in veg. 2 foot 4 bulb T5 will be putting out significantly less power than the light you are currently using for veg. So I guess my answer would be no, don't use only the new T5, it will cut your growth. If you were able to pick up 4 foot 8 bulb systems, that is entirely different, I highly recommend T5s, as long as you go with a big enough system. T5s put out much less heat, so you can put them much closer to your plants, and the light source itself covers more area than other lights. I would suggest you use your new T5 light as a cloning light, it is the perfect size for that.

i'd switch the 600 for a MH for veg. start them out under T5's, move to MH and flower under HPS.

Thanks guys my 600 is a built in ballast so I cant switch it to mh, and I had the t5 on them as they rooted as a clone and they so great I just was curious how much slower they would grow under the t5, under the 600w hps they are ready for flower in 4-5 weeks normally

I have a 2' 4 bulb T5 and it does grow them nice and squat with fat leaves, but it will take about 8 weeks or longer to match the growth of your hps during veg. I have tried both ways and I although I'm not knocking the T5, the hps will get you there faster with much better growth.

100 watts of T5 < 600 watts of hps

Thanks and with the upcoming outdoor harvest season approaching im considering the t5 as its not nearly the heat ao maybe no attwntion as my flower room if off during the day when they fly?

5th grow t5 or 600w hps veg
