LED Light - Veg & Bloom Settings

@StareCase I have a cheap duct booster pulling air out of the top. Temps sit around 82.

With the blurple set-up, it was really crowded up top and I had to put the carbon filter and fan outside the tent.



I know that this is not the most efficient setup but I had limited options. The filter and the blurple housing wouldn't play nice together.

But with the RSpec, I was able to bring it all back inside the tent and reverse that flow.

Thanks B. My temps were probably a little higher than that. I'm glad that I'm switching the lights for flower.

It’s in my basement that is quite cool to begin with.

Your light doesn’t even pull 250 watts. Leave everything on. The whole way. Keep it high. At least 22” to start.

26w/sqf isn’t enough. What kind of light ?

2020 HortiBloom Horticulture LM301H LM301B 3500k Full Spectrum 650W LED Grow Light

This is our best seller Mega Plus 650W, whose power draw is around 650W on the wall, the efficacy we can do is 2.6-2.8 umol/J, we use Samsung lm301b or lm301h plus Cree660 or Osram660 leds, 8 grow bars to cover 5'x5' grow space uniformly. We use mass 6063 aluminum materials on our lights, each bar weighs 1KG, which promise the best heat dissipation to keep maximum product lifespan and minimum luminance decline.

Please contact us for more details, we have more option for you to choose !

The only thing to say is I was planning to do a 4x4 table hydro. However I’m more interested in staying with soil. The light seems bright. Sorry for spamming that but it has the specs I ordered off alibaba.

Yeah that’s a really nice light! Im
no expert though but I still wouldn’t want to be flowering with 25 watts per foot. I think most of the guys on here say more like 35 with decent lights like that.

I haven't put that rig into production yet cause I am still in the early stages of vegging the girls and preparing for the SCROG.

I recall that the efficacy of the blurples was around .7 umole/j. The efficacy of the RSpec is around 2.83 umole/j. 4 times as efficient, great PPFD, low heat, better light spectrum ... really chompin' at the bit to get them into flower.

I figure another 5 weeks to go.
