Test fitting a 7 gal smart pot. Moved in a 2 gal smart pot Space Cheese. Will be up potting to the 7 (~5g as is) Cleaned and rehung the lights with ratchet ropes.

I'd have no prob bending or even tying branches in early flower. Or even super-cropping them, specially in the first couple weeks. But it may also depend on health and vigor. Train, lst, and scrog dem girls early on! I start LST in solo cup / 4" pots, then continue as I up pot. Selective...

I like it a lot! And after seeing/running these Vero 18 5000k @ 700, I think it'd work great to provide some of that Blue spectrum punch that the Cree 3000ks really do lack. I wish I had some blue[-white] in my flower tent just for my human eyes, but I suspect it'd help a bunch with stretch as...

Thank you! I think this design/setup would fit a 3x3 well, its a lot of light at 1400ma. I think the 5 chip 240 setup would be awesome, that is exactly what I considered as well (with the 5000k center). The fans worked on a 6v blackberry charger, but I run it now on a 12v source. All 4 in...

More specifically, "MAX" power is when the blue and white wires are disconnected completely on the B version Meanwells. It is very likely your pot does not actually go all the way to 100k ohms. Unless you are running an additional ~10k resistor (or whatever value your specific pot requires to...

Those components would work together. You could add up to eight 36v chips (~25w each) on that driver if you wanted, it (the driver) would run more efficiently then, but its likely not a big concern. You may not need/want the lenses, specially if you are running 700ma..but thats depends on your...

Some updates from Plink D67F. Trics are mostly milky now, still not seeing amber yet, but i'm still struggling to get a clear view from my scope a majority of the time.. Still seeing run-off ppm in the 1000s+, so she will continue to get flushed until I start to see some amber. Used the WD40...

By what I know from CPU heatsinks, copper is great for 'transfering' or 'moving' heat from one location to another, but it does not dissipate / radiate very well, which is why a lot of air cpu coolers use copper heat pipes attached to aluminum fins, for dissipation. I think copper water blocks...

Been a while since last update. I've since turned the light down further, ~80w total consumption range now. I have temps in check for the last few weeks, peaks in the low 80s *F, normally day-time temps in mid to upper 70s. The plant has shed/lost most of its fan leaves now, but the flowers...

Just an update. 7-8d since adding the Cree COBs. I have them dialed down to ~90w of actual consumption (including driver loss). Currently have about ~12" from light to the top cola. HS temps in the upper 80s, running fans at 12v. In-tent temp max has been between 81-84*F (~3-6* above ambient)...

By looking at data sheets for the driver it looks like 36v is its max (Update: I just noticed this has adjustable voltage up to 40v. Maybe it could work fine at higher amperage as well, I don't have first hand experience/knowledge w/ the A models and dual pots.) A single CXA3070 is rated at...

30v max output rating. (30v * 1.5a = 45w) I see little in terms of heat dissipation in that design.

Maybe I missed it, whats the ~PPFD for the area you flowered in? Anymore larfy/leafy than higher intensities? Most BD crosses dense up pretty nice on their own. Just curious if you have run the same strain under the same/similar lighting at higher intensity.

I've looked into that Blue labs ph/EC/temp meter. If/when my current meters fail (or even just one of them), i'll likely go that route. But I've had great success with these cheapo Amazon units. Used over a year now, no issues. Just got calibration solution for them the other day, they were with...

Removing the UFO lowered temps drastically, and soon after I transitioned to the Cree setup. Also sorting out some pH issues, and making sure all feedings/waterings are ph checked prior. Background is I had trouble with low ph through most of veg (peat based soil lacking perlite), trying to...

Began work on a PVC scrog insert today. >> Album << Designed to fit within a 2x2 ft tent. ~4" squares. ~21.5" elbow corner to corner. I plan to tie it off to the side poles and/or suspend from the ceiling poles. I'll have to see what works. I've learned for my own needs, that to keep plants...

Potentiometer testing results: Min-9 watts (very dim, but lights functional) Max-182w (89+*F hs temps) Switch Off/full power mode-232w (96-105*F) I have it dialed in to 101 watts (including driver). Temps are great! Canopy and upper canopy is now 74-77*F. Running a humidi outside the intake...

Wow, that 4000K spectrum graph looks sweet, broad coverage. Matching the 3000K in the red, but much broader. Alot more green-yellow? than both the other specs. And has a lot more blue than the 3000k, and likely plenty for vegging just fine too! Wonder how the 4000K V22 compares to the 3500K CXB...

Picked up a 100k pot. Tested at 84,300 ohm at max. Wired it up to a switch so I can open the circuit and have FULL power (~200w) OR close the circuit and use the pot (resistance) for intensity control. So I should have a max of ~170 watts with the resistance maxed @ ~84k ohm. This is...

I have a 5" elbow out the top hole, with 6" ducting connected to it. A 120mm PC fan (95 CFM) is fit inside of the 5" elbow. I could try puting the humidifier in the tent..but afraid of it misting the lights with too much moisture, or the plant itself. It does have a humidistat, so I can set...
