I don't understand why you would do that. 65 is fine. Some people argue that the variation is actually good during flowering. Without proper ventilation your plants will die. Don't do that. Buy a heater with a thermostat.

They are in Veg, less than a month old and I have new clones not even rooted yet in the tent. I just don't want the cold hurting them.

Week 5 of flowering in my 4x4. Tried my best to keep the canopy level but they are stubborn to work with.

Damn!! Nice looking bud!Week 5 of flowering in my 4x4. Tried my best to keep the canopy level but they are stubborn to work with.
Sup everybody!
Just scrogged my tent! Going to be flipping to flower soon and couldn't be more excited!
There's a lot of open space but the 3x3 tray i have the plants in is off-centered until I can figure out something to put my oscillating tower fan on... so it'll be more filled out once i center it =)

Gave the Veg tent the 1st trim today.

Is there a purpose to trimming? Mine are really starting to bush up, especially the Indica dominant hybrids, wondering if maybe I should trim them up some or not.
Anyways, got my screen in today and did their final transplant into 5 gal smart pots.

Trimming let's the light in like how some Growers will bend the plant over and grow it sideways.
I notice a burst in growth after I trim. Plus the tent was getting crowded.
I also trim lower branches that won't produce. No need in them sucking up nutes that should be going to the bud sites. There's many options and techniques.

Week 3.5 veg, plants meet your new source of UVA/B lighting .
Installed 2x2' T5 HO lights designed for UV production, here's their spectrum graph and them installed, hopefully it's enough .

That was just the spectrum for the UV fluorescent bulbs I added in
This is the P6 spectrum
There's no UV light on my P6 and really wanted to introduce some, so found some nice fluorescent bulbs for that purpose only .

My LED panel has a little "supplemental" UV fluorescent tube running down the middle. It has a separate switch, and actually has a separate power cord just for that so that the grower can use a second timer for it and run the UV bulb for less hours/day than the rest of the panel if he/she wishes. While this is a nice feature, a grower can do the same thing with a separate (and much cheaper, lol) fixture. The bulb is a ReptiSun 10.0 brand/model and, if I understand this correctly, means that 10% of the output (of that bulb) will be in the UV range. (Obviously, from the name,) it is sold in pet stores for reptile cages as many of them need the UV portion of the spectrum for proper health.
I'm a big fan in general of giving UV to the plants in one's indoor garden. Especially if that garden contains "high-altitude" (take that figuratively, literally, or both, lol) sativas. I would not follow the usual rule of keeping fluorescent bulbs as close to the plants as possible, though - instead, allow some distance as the UV component in these bulbs is much higher than "an average light source" so the small numbers can (IMHO) be somewhat misleading. IDK what the proper spacing/distance would be, though.
And I'd shut off the UV bulb before working in the garden.

I do shut it off while I work on it .
I'd looked into those reptile bulbs, but I kept searching for a bit to see if there was anything different and I came across these. It comes from a series of fluorescents which are like LEDs in the sense that they have specific bulbs for specific nm's(red/blue) and this one which is their UV output one. I started off with the 24" T5 HO bulbs, but they have them in various sizes too, with 2 of these that's 48w focused mainly on UVA/B, didn't want to over do it to begin, may add more or bigger ones down the line

Lot's of people are thrown off when talking about LED output. Few realize they use "Watt equivalent" and not true Watt output. Watts are a horrible way to explain the output of an LED light. I wish the manufacturers would get off watts and showed LUMENS and light SPECTRUM. That's what really matters. All watts are, are heat energy output.

I think they use that to confuse and in a way deceive the average person who doesn't know much about led's and what actually matters as u said. All we hear is watts this watts that but u must look deeper then just the watts. Great point
Er... You mean PAR, micromoles per meter per second, DLI, etc., I assume?

Yes and no, and this is where people gotta look into what they're buying and read a bit.
It's right that when a company labels something as 1200 or 1800w that number doesn't matter, but if you look into the specs it "should" label the actual watt draw, and that number can be used as a useful tool.
I started off with an "1800w" fixture and that number does nothing in help planning anything out, but the labeled 325w of drawn power can be applied to plan out your lighting for your space, it is a very deceiving marketing ploy.
I'm extremely happy with our sponsors P6, no deceiving marketing, a straight up 300w on COB mode, 320w on LED mode or 620w with both on, no gimmicks
620 watts? Nice.
One thing I've noticed about LED grow panels, especially the higher-output ones, is that they do seem to share HIDs' tendency to produce a big hot (in terms of light-energy) spot directly under the panel. I think that's one reason that the strategy of hanging one 50-watt COB per square foot is so efficient - you get equal light distribution throughout your garden's area. Also, the multiple light sources reduce shadows - a plant's leaves might shade some of the light coming from the COB directly above it, but the ones in the surrounding square feet help fill in those shadowed areas due to the different angles.
My panel is only 350 watts, and it's relatively large - but it still has this hot spot. I can manipulate things somewhat by deciding which of its six COBs I run the 90° optical-quality (IIRC) lenses under, but it's still going to be there to some extent. When I received it, unpacked it, and fought to hang the 35-pound thing by myself, lol, I kept wishing it was smaller in size. Now I wish it was larger in physical size, because that way the COBs (etc.) would be farther apart.
I'm just rambling....
