Hmm,Im new also to led.I ran HPS before.I would back it off by 12" or more.
My thoughts are when dimming does the spectrum stay the same?Id just lift the light 8-12" ish and see how much leaf temp drops.If any.
I don't believe the spectrum stays the same. When I turn my light down to 10% the light looks bluer.

I like to transplant into the sip after I've sexed. I worry about dead roots in the reservoir from plants pulled out. I've done it before, but it makes me nervous.
Yep I do the same, see plants in 1 to 3 gallon pots, take some clones as I can and then once they show I add them to the earthbox and flip to flower pretty much right away because they are going to explode in the earthbox

Can anyone help me with a quick question?

I’ve never grown out regular seeds before and I was hoping to use my new earthboxes for the first run. What is the best way to run regular seeds in SIPs without knowing the sex? Would I sex them before transplanting into the SIP? Or just transplant at the normal time and hope that A couple turn out female?

I was planning to run two plants in each earthbox… but that’s not concrete yet. Thanks everyone.
I sex separately too. I cant move my SIPs to rearrange relative to lights for fewer plants so I prefer all Sips occupied with females of the right size

@myke , got a guesstimate about what percentage off the cross section area of your sip, your wick is? I read 10% on an unrelated forum. My patio pickers seem to be in the 10% range. I'm gonna use stainless mesh to make a wick tube filled with straight peat. With these food storage containers, I need about 3.5" around.
Was considering making the wick protrude 3" into to soil container, and to the bottom of the reservoir, anyone foresee disadvantages, as opposed to the plain peat coming just up to the bottom of the soil container?

Just put out a blunt,I think your asking how much area my wick takes up?I could probably fit 7-8 of them in my water res area.I use a 5" hydro net pot its 4" tall.

have you looked at the PDF for making sips in the very beginning ? it has a GREAT set up for making about 15 gallons of soil sips. I made some years ago and they still are going strong! also its a great place to understand the wick to soil ratio and go from there upscaling. :joint:

just ordered up 6 sets of wheels for the earthboxes! They will make them easily movable.... it does suck that it cost me 100 bucks for 24 wheels.. but really even if I bought them at the hardware store and somehow figured out how to make them work, they would add up.

Cool,hows it compared to the other tent?
Um.... well....I started flowering that one much later, and I waited too long.....

The light doesn't go any higher. Stretch is mostly done though. Lol..... she's twice as big.

I'm gone a lot for work, so I haven't had much time for it, and being in hydro she grew fast. This is the first in a 4x4 and I wanted to fill the scrog before flip. Next time I need to flip sooner.

Lol!! Been there. I didn’t know it would stretch that much!! Haha. Friggen hydro eh?
I should've known but somehow I'm always surprised at just how fast it grows in hydro. And Lucas formula for the win again. It takes so much work out of it, and this plant is really happy and green.

I've watched an older video than this but Kyle teaches chiropractic treatment for cannabis the same in this newer one. I do this anytime I need to lower a branch(s) veg or flower. Kyle says its better to do it in veg but I've done it early flower when a stretchy plant out grows her vertical space. Honestly it's a weed and can take a lot of physical abuse before throwing in the towel.

gotcha. I guess your issues different from mine cause theyre heavy. My homemade sips are small, but connected by watering tubes that are cut to length and it would be super pita to move them around.

I will definitely check that out, thanks for pointing me in the right direction :blsmoke:
