Viparspectra thoughts from people that have used them

What would venting the heat out really require could I just vent the other end back out of the closet and into the room

Just as a comparison. I use a 4X4, 7 foot tall tent. Leaves me about 5.5 feet of headroom.
With my xtracooltube, and 600watt hps, I don't need air-conditioning. Even during mid summer. The canopy never gets above 30'C for more than a few hours.
When the room temperature is low, the canopy sits around 26-27'C. Which IMHO is just right.
You do want to be recycling your air, in the room though. Not so much for the heat, but more the fresh air.
Just having a couple open windows with a draft would be sufficient.

Really starting to lean towards hps or cmh what size fan would I need and which would be better a xtracooled tube or just a regular air cooled one

In a 2x3 closet, I'd opt for as much cooling as possible.

I would look at utilizing 2x2 or slightly more of your space and go with a 135w quantum board kit.
If your not comfortable putting a plug on it and poking a wire in a hole then growers lights will provide it fully assembled for $25

Low heat. Good results.

And yeah 200w of QB would beat 300w of vipar.

No one has given me hard proof of why the quantum boards are better then the blurple lights though honestly just lookin for some honest data about that

Actually the recommended maximum flowering footprint of the above 135w QB is 2x3. So bonus!

Heres a pic of a one of my previous harvests. I give each plant 2x2 space and 135 of QB on that half of my flowring tent. Although i use 2x 260w QB kits to cover the QB side of my 8x4.

This was the runt of the litter.

Its because they are vastly more efficent. Meaning much more light output for every watt of power.
A blurple like vipar is less efficent than HPS lighting and a QB which uses samsung diodes is more efficient than HPS.
Vipar, mars and all those cheap lights use really old tech diodes where QB uses one of the most efficient diodes available.
Thats why cheap LEDs are cheap and QBs and other quality LEDs are not so cheap.
But with a small space its a great option and isnt breaking the bank.

Dont get me wrong though, HPS/MH and CMH grow great weed. You just need to vent more air to control the heat becasue you would be using more wattage

The quantum boards output a lot more light compared to blurple lights. They are a lot more efficient. I myself don't mind blurple lights. If your growing for personal use then the vipaspecta will be fine.
I'm about a week away from starting a auto flower grow using actual 600w at the wall from 3 blurple lights. Im planning on doing a grow journal. It should be an interesting grow and hopefully it will shut the blurple haters up. Any light will grow weed. Buy whatever you feel comfortable spending your hard earned cash on and maybe down the line when money isn't as tight invest in the "next" up and coming all the bells and whistles LED that everyone is screaming on about. LED is constantly changing and getting more efficient. In 6 months everyone will be going on how shite the quantum boards are.

If you want 'hard" proof (apart from grow journals), you'll need to do a deeper dive on the underlying science. As @coreywebster said, it's all about efficiency. Those blurples simply do not put out as much light, watt-for-watt, as Quantum Boards. If you truly wish to understand, there are many threads posted here that go into detail about the technical aspects of LED grow lights.

But what kind of yields would I be expecting with that 135w qb like half gram to watt ratio

It's not only the light that effects your yield. Experience, grow medium, nutrients and temperature all matter just as much as the lighting does.

I have no experience with anything of that sort diy that is and that’s why I have leaned towards led i have a very small closet space and heat from the lights making the space to hot is my primary concern I’m working with maybe a 3ft w by 2ft deep closet space

Everything the guys above have said is ALL true. Since you’ve said that heat is an issue I would encourage you to comb over the DIY websites and videos. Building your own kickass LED fixture is not that hard. We as a forum can damn near hold your hand through the process. The Vipar fixtures do grow fairly nice buds... not awesome but nice, you would be better off building a light. You can pick spectrum, intensity and light configuration to suit your grow space. I promise less watts out and more photons to your girls

What Esrgood4u said above i bang on.

Experience , enviroment ect means a whole lot.

My best was 1.67gpw

£230 from China. I'm UK and can't be arsed to convert that into us lol

pay attention to grams per watt and light efficiency.. the higher the better. proof gets no harder or honest, as long as the people reporting are honest that is.

Also, as already stated, most of the blurple lights kick off a good amount of heat.

Finally, you will probably want a carbon filter and air flow anyway so you will be venting regardless of light source.


Good luck!

I have a Vipar600 reflector series, it covers a 2x2 pretty well for a blurple light... not a 2x3 not even close. If you are new to growing and not into DIY shit and you can’t handle the heat then go ahead and get your feet wet with the 900 vipar. You’ll be just fine. I mean damn you’re not trying to win a cannabis cup just yet. Have fun and learn to grow. Peace

I don’t know much about hps besides the fact that they usually look very large and cumbersome because of the hood and fixtures they are in which limits the little space I have even more and I’m not sure how I would go about venting the heat out but is one of the newer quantum boards really worth it I could only afford one of their smallest ones at this point think it was around a 240w would that actually put out enough lumens to grow enough to justify starting off with one of their smaller boards at first

Click to expand...

That 240w will do better than a 400w viparspectra

GPW means nothing. You can either grow are you can't. Simple.
You want high yields pick a high yielding strain ffs.
Make sure you have total control of the environment your using.
Select the best medium to support the girls. Feed them correct amounts of nutrients (remember. Less is more). Ensure external airflow and proper filtration is constant. If 1st grow use a compost as you don't have to mess on with PH meters. Ensure you have timers on the lights as it's easy to forget to switch your lighting on or off. Provide enough light that they will reach up and pray to the light. Good luck whatever route you decide to go. You can grow for as cheaply or expensive as you want. I'm a cheap arse so no chance I'll ever put £300 into a single light.
