    Best grow light for a 4 x 4 ?

    in Grow Community

    Hey guys, Newbie here thanks for your input. it’s seems like the more I read about lighting the more confusing it gets. I’m currently In the middle of flowering of my first indoor grow. I wasn’t sure how serious I was So I started fairly cheep. but now im ready to upgrade some equipment. I’m looking at lights and I kept going back to the Mars Hydro TSW 2000. I appreciate your input. Tks.

    i run the tsw2000 and its great light plants love it . its for 3.5x3.5 for flower but judjying from the power that it has i think it will be ok for a 4x4 . i run it on a 3x3x2 and i have never managed to go over the 75% mark on the dimmer . so if money is an issue in my opinion it will be ok for a 4x4 . but look more about it cause im also a beginner . hope i helped you

    budget, no more than $650 - a $700 range. ( any more then that and the light should also water the plants for you!) I guess what I’m seeing is:

    Mars hydro TSW 2000. Spyder Farmer SF 4000


    Advertised 4 x 4 5 x 5 coverage

    fine print

    coverage

    Veg. 4 x 4. 6 x 6

    Flower. 3.5 x 3.5. 5 x 5

    Power. 300w. 450W

    cost. $270. $559

    so the Mars is not giving adequate coverage during flowering (3.5 x 3.5 coverage in a 4 x 4)

    and the Spyder is a bit of over kill for a 4 x 4 and draws 1 and 1/2 times the power. . I guess the bottom line would be quality and yield. Is the Spyder worth it?

    There are a lot of people that run the SF4000 in a 4x4. Since it now has a dimmer on it you can reduce the output if you feel necessary. I ran the SF4000 for a grow and didn't have a dimmer on it. I wish it had one. I would rather run 2 of the SF2000 in a 4x4 instead of one SF4000. Two of the SF2000's would provide more flexibly like if some plants were to grow taller than others you can move one light up and leave the other low for the smaller plants. It also provides a better light spread across the footprint since you can space them out more. I haven't ran the TSW 2000 so I don't have much feedback on it. Also if you go with Spider Farmer, I do have a discount code so you can save a few bucks. Spider Farmer discount code: MRGROWIT5 Edit: I forgot I have a Mars Hydro discount code too lol.
