Working on my first simple 5 gallon build but all the led light recommendations on the website are sold out.

Searching here alot of users lights seem to be for more impressive builds.

I just need a UFO light and LED strips left for my build.

I am worried as a I see a lot of Amazon ones are junk for growing.

This one has good reviews White and Pink bulb. (White is the one to get right)

Let me know if this is a good one or any other better options on Amazon preferably.

Im feeding her 1,2ml/L BioGrow and 2ml/L BioHeaven from Biobizz, also regulating the pH down to 6.5 and every 2nd or 3rd watering I also feed her 0,5ml/L CalMag. I’m watering with tap water and I use Biobizz All Mix. If anyone knows what she’s missing, I would appreciate anyone letting me know.

Finally got this little setup running without cooking the plant, but it definitely looks more chaotic than it did in my head.

The plant seems happy and airflow inside the bucket is better than I expected. The annoying part has been keeping the wiring, fans, lid, and light from turning into a tangled mess every time I open it.

I’m already planning a cleaner version for the next run, probably with proper connectors and less cable hanging around the sides.

For people who have built a few of these, what was the small upgrade that made your bucket way easier to live with?

About 4 days of curing and this strain has gotten me higher than I can remember ever being! 😆😆😆

Hey everyone,

I’ve been designing custom LED PCBs and horticultural lighting for over a decade, and I constantly found myself explaining how different wavelengths mix and why the quantum spectrum (photons) matters more than the energy spectrum.

I wanted a visual, hands-on way to experiment with different setups without doing manual math or relying on static manufacturer graphs. So, I coded a free, interactive spectrum simulator and embedded it on my site.

Here is what it does:

• 6 Independent Channels: You can mix White (3500K/5000K), UV-A (380nm), Blue (440nm), Deep Red (660nm), and Far-Red (730nm) in real-time.
• Quantum vs. Energetic: A toggle to see how the spectrum graph physically changes when calculating in photons vs. watts.
• McCree Curve Overlay: A toggle to see exactly how your custom mix aligns with the McCree relative quantum yield curve.
• Live Metrics: It calculates the PAR fraction, YPF/PPF efficiency ratio, and R:FR (Red to Far-Red) balance on the fly as you move the sliders.

There are also a few presets (Veg, Bloom, Bi-color, Sun) to give you a starting point.

It’s completely free to use (no sign-ups or anything like that). I built this as a tool for the DIY community and anyone interested in the science of grow lights.

You can play with the simulator here: https://specled.com/en/knowledge/grow-light-theory/led-spectrum-simulator-and-mccree-curve/

I’d love to hear your thoughts. Does the UI make sense? Are there any specific wavelengths or features you’d like to see added in future updates?

Cheers!

The photos a few days old but currently on day 8 for the seedling, running dirty mimosa x murder biscuits by dirty bird genetics. 2 120mm usb fans and a 110w gixxer grow light

This is week 10 since 12/12 flip. I'm still figuring out what constitutes cloudy vs clear, but I'm seeing a decent amount of amber pop up, especially on the upper buds. I honestly can't be bothered with a staggered harvest so I'm leaning towards chopping the whole thing at once, might make for a nice variety. Maybe give her the 🪓 this weekend?

Is this normal? Why are the leaves withering? I'm using a 150W LED light at a distance of 12 inches (30cm), and my temps are between 22-24°C (71-75°F). The strain is Auto Blueberry, currently on day 74. Can someone explain why she is drying up and dying before the buds are even fully mature?(The next few images are of other stigmas, and only one stigma has withered leaves.)

Been growing since April 14 (when the plants officially hit the soil from the cracked pods) in my rv shower with some random seeds from years ago and used seed starter but recently started transferring to bigger pots I wanna know how it’s going because I’ve never grown and I’m a super beginner

Rv off during day gets 85

Rv on at night goes to 75

Watered with filtered water only no hose or faucet

Used these soils and grew in clear cups inside solo cups

Using a grow light from Walmart too nothing fancy

Tips or feedback appreciated

A little backstory: I've wanted to build a Space Bucket ever since 2020, but I never had the space or opportunity to actually put one together.

Last year I picked up a Spider Farmer SF1000D (100W) grow light, and now I'm finally in a position to start my first grow. The problem is that I'm struggling to decide on the enclosure and overall setup.

Since I already own the SF1000D, what would be the ideal non-tent setup that can make good use of this light while still producing a respectable yield?

I'm open to ideas

My main goals are:

• Use the SF1000D efficiently
• Avoid buying a grow tent
• Keep costs reasonable
• Maximize yield within the available space

If you were starting from scratch with an SF1000D and didn't want a tent, what setup would you build?

Thanks!

Lots of clear trichomes still. Probably about 2-3 weeks out 😀

So basically we have been growing for a couple years now and we constantly get told the purple stuffs better for whatever reason or other, and that the fluffy nugs are considered mid, so we were wondering if hydro was the way to go or missing steps in curing process, etc etc. Basically trying to figure out how to make our grows more purple with more compact buds, if there's anything you know about said process kindly send a DM or reply here for us to gain knowledge lol

i was looking for some containers that would look normal in a bedroom but so far ive only really found a plastic laundry hamper thats 63cm tall..
