ANY light will work. Buy the cheapest one you can find, $35 Amazon Blurples will grow as good as a $1500 powerhouse. If you're on a budget take care of your enviroment first, that's where growers need to splurge, enviroment. Treat yourself to an overpriced light after you've grown a couple crops.
But I get it, ACs and Dehumidifiers arnt cool. You can grow great buds with a generic light but you
cant grow buds in a bad enviroment. Your dehumidifier should be the heart of your gro-op. Buy the best one you can afford.
Researching lights is the worst. Millions of opinions, millions of salesmen, millions of opinions by people that have only used one light and millions of first time growers heralding the brand they chose. Caught up in the hype.
If you're growing in a room as opposed to a closed tent, look into HID lights. They're cheap. They cost a little more to run but in the long run they're cheaper...it takes several
years to save money with LEDs and by that time they may turn toxic, burnt out diodes, or die leaving you buying another expensive light.
Example: say your HID costs $10 more a month to run (high estimate), that's $120 a year. How many years will it take to match the price of a new LED? 3 years for a cheap fancy LED like
Spider Farmer or Mars. 9 years for an expensive LED and 15 years for a top of the line LED. Just something to think about.
Another thing to consider is LEDs don't have good light penetration like HIDs do (especially CMH). LEDs will grow buds at the top of the plant but struggle with the lowers and lower lowers. I'll add a pic of lowers grown under a HID if I have one. Then there's the heat rays, LEDs struggle to warm up your plant, that causes deficiencies. You'll need to run your
whole grow room warmer, mid 80s to make up for it.
If you're confused about what I just typed just know that you don't need an expensive LED, a cheaper one is just as good.
I'm not here to argue I'm just being real. Do what you want with my information, that's your choice. Either way you'll grow some nice buds.
