Im looking to keep plant around 3 feet
Counting the container or not?
If not, then you'll want a 7' tall tent and HPS or CMH (or LED growlight fixtures, if you're intent on that. Or, household LED lightbulbs, which would be inexpensive in the long run, but can be work to manage, especially if it's a 4x4 tent with 4 plants.).
If you are counting the container, then a 4-5' tall tent would work. T5HO works well in that. As does the lightbulbs. Or, some LED fixtures, if that's your thing.
Unless you have a reason to use LED, I'd stay away from it. It's a confusing topic and a lot of predation out there. What I like about *not* being into LEDs anymore is that I can focus more on growing. Lighting is just a means to that end. LED turns into growing to demonstrate LEDs. Growing becomes a means to finding the LED holy grail. It's different. It's not as fun. And, there's religious overtones to it. It's hard to be objective about it because people are growing at 80w/sq ft but bragging about the buds as wonderful. You can't compare that to HPS or CMH (or T5HO, or lightbulbs) when decisions are made from those kinds of testimonials -- which evolve from "I liked my first fixture so much, I bought two... and the results are spectacular. I think a third one would fit in my grow space." (No mention of how that will be 120w/sq ft.).
IMO, it's a proverbial pandora's box. It's not so much a matter of whether the BS "1000w" fixture will grow (within 1 or 2 sq ft). It's more: do you really want to be part of all that? It's like rolling the dice on lighting. There's a reason the old standard lighting has virtually no controversy. I'm sure you can find some no-name crappy T5HO tubes. But, it's not the *norm* the way LED grow-light BS is. You'll just grow, and replace standardized tubes/bulbs/ballasts. You don't have to get into whether a fixture's specs saying "Osram" really means it really uses Osram diodes, or just includes *one* so they can say that. (That stuff really happens, with the majority of the fixtures you'll looking at.).
But, $80 isn't a lot to roll the dice on. People have spent far more on fixtures that ended up in the dumpster a few months later.
There was a guy on another forum 4-5 years ago who went
completely off the cliff with TopLED/Mars/Sara lights. He had some kind of legal judgement which was a windfall, and he was going to grow *big* all at once. Thousands of dollars for lights. He bought two dozen Mars fixtures, giving the finger to everyone saying "I wouldn't." Within 2 months he was buying COBs and heatsinks, making his own fixtures and admitting he wasted money. (He made a video of him beating the crap out of his fixtures in front of a dumpster.).
I haven't looked at LED for 4-5 years. It could be better. But, from what I'm seeing, it's still like a timeshare presentation.
