That cut off end needs to be replaceable otherwise light will get into your water and create algae.

I hated that strain so god damn much. Huge biomass in Veg and absolutely NO YIELD WHATSOEVER in flower. smelled like burnt rubber too... lemme know if yours is similar, would ya?

I can tell you he didn't. ANYTHING that WATER can pass through, ROOTS can pass through. End of story.

Really, I haven't built many fixtures using boards at all. But you just need to know the voltages of each strip, and their average current rating, to lead you in the right direction.

I'm strictly speaking in terms of plant physical heights being varying. One corner may have some seriously stretched branches that need more space from the light.

You won't have problems. Just run it. Plants will take what they need just don't blow them out with 1300+ppms or some insane shit like that. Just start flowering at 500-600 and be around 800-1000 poms mid flower and everything will be smooth sailing.

This is why.

You'll hate using single buckets. Connect then and add waterfalls to them and have an RDWC setup. You'll have a control reservoir too so you can add nutes, water, drain, or whatever. https://www.rollitup.org/t/i-gotta-lose-the-air-pumps-how-plus-my-awesome-mini-dwc.960807/page-3#post-14262160...

They have a bad track record. Doesn't .ran their new fixtures aren't putting out a dope spectrum and using new tech. But all I'm saying is the same tech can be bought for far cheaper. I do like the blue they add.

I'm more impressed that was done with an SP-250 that uses all Epistar diodes!

My bad, wrong link. But if you're thinking the optic doesn't have 8 bars, you're wrong.

Yeah, the HLG 550watt power draw model would be an even more perfect situation because 4 of those would equal your HPS power draw exactly at 2200watts.

Yes. 4 600 watt LED fixtures should work.

Power consumption is less with LEDs for the same output as HID. So basically 600w (probably closer to 500w, honestly) of good white based Samsung lm301h LED IS EQUIVALENT to 1000w HPS.

It doesn't. They're being lazy or is without product.

God, I wish I had your job..

Here's your "optic slim 600H" https://m.alibaba.com/product/62127005146/Sinowell-Flexstar-180-Degree-Foldable-Dimmable.html?spm=a2706.7835515.0.0.deef1fcdPGgU5c&__detailProductImg=

You positive it pulls 400w?

3000k all the way. Especially if you can turn your reds off with a switch on the board.
