I will defer to @dbrn32 for expertise, but I keep notes on his recommendations.
For a 4x4 space, my notes say:
Two HLG 260 XL kits.
Oh, I just noticed you said you want to grow 6 plants. That will be tight in a 4x4 space - most people would grow 4 plants (4 sq. ft. per plant) in that amount of space.
If you decide you want to expand to a 5x5 space, the lighting recommendation would be:
Three HLG 260 XL kits.
Growing marijuana gets expensive quick!
Yeah, Tommy, growing can be very expensive but cheap in the long run if one nos what in the hell heās doing. Those kits are around $360.00 each so 2or3 would be over the top. I would have to sell my first-born son to pay for them. And heās an adult working in law enforcement and probably wouldnāt go for that. Can u recommend an LED under $200.00 that would allow me to grow 3-6
beanstalks like Jack climbed?
One final stat. I have an empty 18ā x 30ā room devoid of light so space is no problem.
I donāt believe such a fixture exists. You could probably go with air cooled 1000 watt hps fixture for probably $200-300, it would also require a duct fan.
Yep. HID (High Intensity Discharge) is the way you want to go. It was the defacto standard for a long time, and is still a perfectly viable solution. Expounding on what @dbrn32 said, you want:
1000 watt HID fixture, air cooled
Digital dimmable ballast
Metal Halid bulb for vegetative stage, High Pressure Sodium bulb for flowering stage.
Iām not endorsing this particular product, but I wanted to provide an example of what weāre talking about:
By the way, in case youāre interested: growershouse has a really good deal on a 4x4 tent package with just about everything you would need to get started: 1000 watt air-cooled HID setup with both types of bulbs, exhaust fan, carbon filter, circulation fans, outlet timer, and some pots to grow in.
It is part number 4x4-1000HID-S
Hey dude, thanks. Iām looking into it. So much info on this site.
Regular HID lighting is what I have worked with for many years. Works great but the heat is a major issue. The package deal above is worth looking at. If I have to replaceā¦I would go that way.
Not an electronic expertā¦no experience with LEDās. The price range stops me.
Will look into it once I win the lottery.
BTWā¦I made a pvc frame to hold the light. 1.5" pvcā¦a couple of 90 elbows and two tees.
The key to HID lighting is to use an air-cooled reflector. All the heat gets sucked out of the tent.
