Harvesting using 3k Sunpulse Lamps

I just harvested four organically grown girls; Ace of Spades, Cheesequake, Blueberry x White Rhino, & Afghan #3, and experience a huge reduction of weight in comparison to past harvests. I am currently using x4 600w 3k sunpulse lamps.. In the past I have used HPS and Ceramic Metal Halide, which seems to have worked the best so far.


This harvest, I had a great resin count, but other than that... a sad excuse of yield. The Cheesequake did amazing, even under circumstances, but I could really use some help. I have another batch in the same room about 3-4 weeks out, and really need a better density/ overall yeild.


Along with the 4 600w lamps, I am using a A/C unit, and am injecting Co2 regularly. I will include photos, soon.

Well not to be negative, but the sunpulse is a metal halide light, not really the right section.

But that doesn't mean we won't help

Ayway metal halide lights are great for maximizing potentcy in both thc content inside and outside, but it really does hinder the density and overall yield. Thats why cmh is popular in the right circles, it combines both technologies, in a way.

I would get a few standard hps bulbs and at least do half and half, usually more like 75/25 hps to metal halide.

So add some hps in there and make sure the lights are as close as you can without burning your plants or sacrificing too much coverage area.

I was sold on the bulbs mainly because the spectrum availability.... I was extremely confused with that idea myself at first, but was reassured over and over again that even though they are MH, the spectrum available could be targeted towards flowering stages. When I began using the CMH, it got me interested in exploring other lighting out there other than HPS.

I will be honest, i am not too informed on these bulbs. Ill have to catch myself up a bit.


There is a difference in being able to work, and their ability to give you exactly what you want. I would still blame the metal halide's lack of flower power here, but like i said, im ignorant on these bulbs, so i need to brush up.


You might try posting this, as well as pictures, in indoor or a few other forums. A little broader traffic/response.
