Light question

I got the mars hydro ts 600 for my 2x2x4 so far so good. I would recommend that or the ts1000. Also it's cheaper on there site than Amazon and ebay

oops -- graph = table.... 2 tables of related use.

anything with lm301b/h diodes, some 660reds mixed in as low as 4% of total diodes and you are good. the spider farmer and hlg are awesome options. get a fan blowing on them to reduce to 25C or less to realize advertised efficacy. It may cost a bit more upfront, but will be cheaper over the lifetime and last longer than the ~$100 options that seem okay, but not so much when you get your electric bill. Please pick cheech or oimrausch rather than this answer -- i am not eligible for the contest related to these answers, so don't pick this. i just wanted to support both of those solutions below for the same reasons listed above. check out my submission for the GD Copywriter contest. I have a graph and it contains the min/max umol/s you'd want for that 2x2 area. math is done for you. With only 36" in height, the greater efficacy will be hugely beneficial to you. Low profile quantum boards or the SF rigs can maximize height and still have sufficient airflow above light. Definitely get some fans blowing up there. won't reach "2.7umol/J" if it isn't 25C.

I will be able to spend up to $120....this is my first grow. I've had great luck with what I'm using so far, but I think it's time to upgrade the type of light now with what money I have until the end of the month.

Hey Mikes Girlfriend, What are you willing to spend? For about 180 Bucks you'll get a Spider Farmer Led, that will fit exactly in your tent I guess.. And it's a good grow light. Hope this help, Cheerz and have a good one!🤘 OimRausch

For the money and the room you have to work with a bestva or king led brands are good for the price. A 600w should do perfect.
