Vertical in small tent possible?

I don't know if t5's would work quite as well compared to led strips? Can always change the HID out for a 10k mh towards the end for the UV?

My idea of growing vert in a small tent would be 1 plant vegged for 8-12 weeks, topped 2x, 315w cmh above, 400w of led strips (bridgelux or Samsung) on the sides and 200w of 2200k redmeat luxeon cobs up top? 3100k cmh could do with more reds and IMO that combo would work very well

Edit; here is my actually fully sick plant so excuse that, 315w cmh + 250w bridgelux EB strips

She still bulked up all the way down.

I was just agreeing that the op could use the t-5's for veg and save all the more powerful lighting for flowering.

I veg with about 250 watts of t-5 with 3-4 plants growing at different stages and plug in a 1200 watt Hortilux super hps flower room as they get harvested.

The iPhone flash was used to hide the hps light.



I am considering adding either my 315 LEC in the middle or some 4' uv+ bulbs along the wall about middle plant height.

I have been waiting for led to get as good as t-5 but don't believe it can be without uvb.

You get the flavor bump but not the thc.

Yeah considering all my problems she's packing it on and still has 4+ weeks left to finish!

Definitely could use t5 for veg then side lighting. I really think current (Samsung/bridgelux) leds will outperform in almost way a t5, during flower the t5 may give better quality than led alone but that's why the led is supplementing a 315w which has a broad spectrum?

You can buy 200w strips + driver for about $100 us which will last 10+ years and is 50% efficient.


Nice room! Why isn't the 315w in there at the moment is heat holding you back in summer?
Do you think changing those 2 x 600w HPS to 4x 315w cmh + 600w led strips around would do any better?

I spent all year before summer comparing hid's. I compared the 600 horti's and also a 600 blue mh and a 315 3100k Phillips.

What I found is what the university of Michigan has determined. Too much blue light makes short leafy plants. Supplement a little blue with the red is their recommendation.

For leafy greens the advice is reversed. Full spectrum with tons of blue light to grow leaves.

I can't say about multiple 315's as I only have one but the best nugs consistently came from 2 hps and 1 315.

Individually. The colors and smell and maybe frostiness was better with the 315. But the density, yield and general size and togetherness of the buds is better with hps.

1 of each mh to hps also was too much for me.

I am now comparing hps only to the other results. But I miss the 315 already. As a supplemental light it is awesome.

But it ultimately cost me 30% yield average per plant and the buds were much leafier and looser for the most part in my system.

Multiple 315's and a sog or scrog and you may have something. But no real penetration like an hps.
