Sorta wavering on doing a full grow with MH/HPS. I can see the plants are small and some grams/watt ratings have been catching my eye and haunting me. I haven't done a deep dive research on lights, yet. I have been trying to soak up comments you guys share about your lights, though.
Original Plan: Get a grow or two under my belt in this 2X4 and start forming opinions on what I think I'll want in a dedicated grow space. Hold of on upgrading the light until I can get something properly sized for the future space. I was thinking, why spend money on a quality light that won't be suitable for an eventually larger space.
Current Ponderings:
- The 2X4 could potentially see continued use for veg. Maybe, I can find a decent light, now, that will also suit for veg later.
- I notice that some lights can be daisy chained. If I find and like a light suitable for a 2X4 - 3X5 space, maybe I could add lights in a bigger space.
- Would it make sense to add some supplemental lights to the MH/HPS set up?
- Should I start watching Marketplace and try to pick up a fairly priced used LED light that may not get me where I want to be, but improves on current set up?
- Stick to my original plan and learn what I can from growing under MH/HPS.
Speaking of Marketplace: Someone recently posted a never used Mars Hydro set up with tent, light, exhaust fan, etc. Not a great deal, but I don't see many listings near me and I researched it a bit. The light is and SP3000. I've seen some negative comments about Mars Hydro's lights. Elsewhere, I've read more favorable reviews on their newer lights. In my head, a Mars light with Mars Adlites sounds interesting, if they're making decent lights, now. For all I know, there's no advantage to running their Adlites with their grow lights versus any other brand of grow light. I also don't know if their Adlites are good supplemental lights.
Since I'm already using ACI's UI, are there advantages to going with an ACI light? Or, should I forget about the brand UI and supplemental lights and focus on trying to find the best possible grow light?
Just for kicks I looked up a comparison between the Mars Hydro SP3000 and FC4000. Is it the Samsung diodes, light spread, both, or something different entirely that earns the FC series the better yield rating?

In that light comparison, the FC 4000 is better by a ton. Those stats are pretty much telling me one light can get the job done and the other will "work" but continually come up short at harvest.
Ignore the gram per watts stuff would be my suggestion.
Focus on the grow space and getting it dialed in. If it's as close to 100% dialed in as you can get, yields will come without even trying.
Your biggest yielders will be sativas and they're also the longest flowering and most challenging to grow indoors. If done well, buds the size of a small child are possible.
Next in yields will be hybrids. Most of the seed stock around is hybrid at 50/50 with some leaning towards sativa or indica. Hybrids can yield great with colas the size of human forearm to around beer bottle size with excellent density.
Worst in yields are indicas but it's not like they're not worth growing. Colas the size of large lemons or goose eggs, maybe fist size, very dense, very potent, and choice in medicinal grade.
Next, adjust plant count to max out that yield potential.
Say in that 3x5 and how I'd grow it would be 4 sativas, or 6-8 hybrids, or 10-12 indicas.
But yeah the first thing is get dialed in so max yield potential can be had then make the best fit possible in training, plant count, and herb needs.
The Mars FC4000 light and the ACI Ionframe lights are the same lights for the most part. Same drivers and diodes but maybe different count and branding. Those two lights and another brand I cannot recall are all coming off the same factory line in China. These are all very good lights. I have the ACI version and I'd rank them a 9/10 and can hold their own vs much more expensive options out there.
You can also run any light off the ACI controller. You'll need the UIS plug. You plug your light into the plug, the plug into the wall, and the UIS cable to the controller. Your controller will then become a light timer using the schedule feature.
Your source to create smart growing systems with components including advance grow tents, inline fans, clip-on fans, LED grow lights, and UIS™ controllers.

The results from the LED and the MH/HPS are very similar. The difference and why more use LED now is less power draw and more efficient spread compared to high watts and a single sweet spot.
Heat output is about equal. LED used to run much cooler but the good LED that deliver what we want run very hot.
I never know if I need supplement lighting until after a grow for the most part. I can use a meter to find out if I do today but before I had I just had to wait and see what I got and where I came up short.
I've bought and sold a lot of used grow gear and once upon a time was a sort of side hustle for me so I may have some useful insight about doing that....
Most often the equipment is somebody trying to recover cost of a failed grow they've given up on. Haggle the fuck out of these guys. They know they can't grow, the shit is taking up space, they need the money. You're in control of that deal.
But along with that, it's gonna be gear that was lacking performance, maybe mid-tier at best, and could be one of the reasons the seller failed at growing.
Look for date stamps on lights to give you an idea of how old it is and use that info in haggling. Ignore his "only used for 1 grow" sales pitch.
Look for hi end gear as well. There's not a lot out there but it's out there. You'll save a ton and get quality long lasting gear. People usually take very good care of this gear and sometimes it's new in box and just overstock on a commercial start up and could still be under warranty.
