SF4000 is 4x4 flower and 5x5 veg (or so they claim). Depending on your budget there are some good choices for a 5x5 flower footprint, but the ones with the best flower spectrums and PAR maps are pricey.

Unfortunately, plants don’t read the labels so they don’t know what the mfr wants them to do. There’s no one size fits all feeding protocol for all strains/phenos. It does look like a bit of nute burn. Try cutting back the concentration by 5-10% and see what happens.

It looks like part of your problem is the plumbing itself. The drain tubing is stressing the grommet/ silicone seal. Try putting in some 90 degree elbows instead of bending the tubing against another bucket. Won’t fix your leak but it may help prevent another one.

If I've found the right light on Amazon, you have the Exlenvce 1000w @ $108 which is a 132w fixture. When you answer HydroKid239 about the size of your grow area, we can make some suggestions.

The Photontek 600w is the same as the Lumatek Zeus 600w Pro that Migro evaluated and raved about earlier this year. They're the same company - Lumatek for Europe and Photontek for US. They use Osram and Philips diodes ... much like FLuence ... and have very comparable stats with the Spydr 2p...

Each 5x5 grow is a single strain and has it's own nutrient reservoir regardless of whether they're in a 10x10, 2 5x9s, or 4 5x5s

That's almost a recommendation for 4 5x5s :) And who in the world can smoke a perpetual grow 10x10?

Shhhhhhhhhhhh

Good point. Although I can partition off sections and run a 24hr UV-C sterilization process in the larger tent.

Love to but the space doesn't lend itself to that format. Bringing in tent(s) doesn't require any approvals while sheet rock and 2x4s will cause some issues. I'm leaning towards the 10x10 but if there are any negatives to the large format vs benefits to the 5x9s, I figured this would be the...

This setup is just for flower ... veg and mothers have their own "habitats" :)

Getting ready for a total rebuild and I wanted to hear your thoughts on the relative advantages / disadvantages of the 2 flower options I'm considering. Either way the lighting options will 4 x either FLuence Spydr 2i, Gavita 7000e, or Photontek (that's the US version of Lumatek) 600w. The grow...

I've been growing hempies in 4 gallon square buckets ... top fed ... Botanicare Ready Gro Moisture Blend over 2" of River Rocks. I'm looking at switching to 5 gallon round pails for my rebuild with the same medium and I was looking for a way to keep the coco from mixing with the stones in the...

Note to self ... drink morning coffee, read panicky notes from suppliers, search forums for confirmation, THEN post requests for additional info. Duh.

Just got a note from one of Samsung's Chinese strategic business partners about Covid related shortages of these chips and that they're temporarily changing to lm561 S6 chips and redesigning their strips to maintain high ppfd. Anyone else hearing rumbling about this?

I only continued correcting you this long so you wouldnt make newbies make poor decisions. But now that it's Brady and Brees I'm out.

The cost of the better 600W+/- Alibaba LED fixtures, landed in the US is $700-$900. You're living in a dream world. Here's a good Meiju fixture https://www.alibaba.com/product-detail/Meijiu-A8-2020-New-650W-LM301h_62499513956.html?spm=a2700.icbuShop.82.16.3d6c660dACeD57 Roughly $475 FOB China +...

So taking outdated costs for a 600w DIY LED fixture, and figuring that you need 4 of them for an 8x10 room, and considering the increased costs for goods at the moment, at a minimum you'd be looking at $2800 - $3000 ... and that assumes someone has the time, skills, and desire to build 4 lights...

Unlike that Vivosun HPS fixture, a 400w LED fixture doesn't put out enough hear to bother your house framing. What you will gain from having reflective walls, ceiling, and floor is a lot more light on your plants and the ability to maintain a "mi Depending on where you live and the temperature...
