Looking to upgrade in 2x4

[Phillihp]

Alrighty,
Bought myself a SpiderFarmer 2x4 "kit" last Black Friday to start growing. It came with the SF2000 light. I've got two grows on it with pretty good results...
First grow was Grimm Genius Juice x C99

Second was SpeedRun Pound Dawg


Anywhoo, while it worked fine, I'm not keen on the idea of running something "weaker" at 100% all the time as opposed to running something stronger at 80%. I like the idea of having some "extra" in reserve if I need it. Anyway, I was looking at the SpiderFarmer SE4500, but then I started looking at the Mammoth Nova Sun individual 40" bars. Thoughts on those? Also, I'm also running an ACI Thermoforge (tent is in the basement, and got pretty chilly in the winter months), and a Cloudforge (I won in a Bud of the Month contest) which reallly helps control VPD.

Oh, and I'm using Promix HP in 5 gallon bags, tap water, Jack's (veg and bloom formulas), with FF bushdoctor calmag.

I got the SE4500, just about finished my first flower run with it. I am pretty happy with it!

Your setup sounds solid! For the lights, if you had the extra cash, I would def go with the nova sun 100 watt bars, just for the fact of they are multi purpose and mobile, so if you ever decide to go to a 4 x4 , you could repurpose them elsewhere as undercanopy, side, inter canopy, etc lighting. Mammoth also from what I understand has very good customer service. Your wattage you have now though is probably sufficient if your not supplementing CO2. But adding a 100 watt mammoth would definitely be in the sweet spot for ppfd and yield increase. And why in the heck are you growing with 5 gal bags with salts. Max size you need indoors is 2 gal, especially using pro mix. Just a thought brother. Believe me, you will grow faster healthier plants in smaller containers. When growing with salts,initial runoff and drybacks are essential, hard to do drybacks in anything larger than 2 gallons.
