3000K vs. 5000K Space Bucket Update: 01-25-17

Time for another update on this log, but first, a quick note: I shut down the forum section on the site since it was causing a lot of problems with bots sniffing around and spam users registering. There wasn’t a whole lot of discussion going on anyway, so it’s easy enough to just do away with it. That being said, I’d still love to chat about any questions you guys might have, see your builds, or just shoot the shit about any other interesting LED stuff. From here on, just hit me up on twitter or Facebook, or use the contact page on the site.

Now, the buckets! These peppers are doing great. They look healthy and are moving along nicely. I transplanted them from their cups into some 1 gallon containers tonight, as their roots were starting to circle the cups. It’ll be a little more crowded in the buckets now, but they have a ways to go before they outgrow them. Both groups of plants are growing at about the same pace. Again, the 5000K Scorpion looks stronger than the 3000K Scorpion, but the 3000K Brainstrain is a little bigger than its 5000K brother. It’s pretty easy to tell the difference between the different peppers, just by the color of their leaves. Both scorpions are a lighter green compared to the Brainstrains.

Until next time.

  1. Well done on the A/B testing. Most people would not even bother with doing their own testing and just rely on what they can find on Google.So the 5K looks to be on top at the moment?

      Thanks! It’s been fun watching their progress. It’s neck and neck right now – I’d actually give a VERY slight edge to the 3000K at the moment. Check out my latest post for a picture I just took of them all together. I’ll do a detailed update showing which is which soon too.

  2. Sir,

    In your opinion, are you truly able to keep temperatures in check via an exhaust fan? If so, what is your ideal annual growing temperature inside bucket and how do you maintain such? More-so, please include your 4 season average temperatures where your buckets are located if varied. Would a digital STC-1000 fan controller help maintain such temps.

    Finely, your conclusion regarding the light spectrum for veg and bloom? Would you run just one spectrum through the entire grow?

    Again, love the site.
    Jim

      Hey Jim,

      The ambient room temperature will definitely play a big role in how difficult it is to keep temperatures inside the bucket in check. I had no issues because it got down to 14 or 15 degrees Celsius in my basement over the winter – it was actually a bit too cold for the peppers. Up here it can get down to -30C in the winter pretty easily and the summers go up to about +30C. Most bucket builders have no issue managing temperatures inside the bucket with a combination of intake and exhaust fans. A controller with contact closures like the one you’ve listed would be a great idea if you only wanted the fans to kick in when necessary.

      I’m sold on the idea of 1 spectrum for the whole grow. Both my 3000K and 5000K plants produced very well and the differences between the 2 are pretty slim. If you’re using one light fixture for both veg and bloom, I think mixing colour temperatures of the lights in that fixture would be a great idea to cover all the bases.

      Thanks for chiming in!
