How much harvest can I expect from four plants?

its tough to really say, alot determins the yield. But i think the average is .3 - .5g per watt. They look good though, their going to full that tent right up. Im curious on how the Blueberrys turn out. i have one in veg right now from seedman

 

Hard to say with LED since they don't penetrate as far down the stalks. Generally I base it off 1000 watt DE which can range from 1lb to 3lbs a light depending on strain.

Just to throw a figure out there. And im not the best or most experienced grower on here by far. I have recently finished a 4 x 4, four plant grow with a 600w HID. So similar set up to you and pulled a pound (just). I used a Scrog.
But unless your running a strain your familiar with its not an easy question to answer

 

Probably around the same. 1 lbs

come check out my grow
Stayhigh7o2s grow room

 

Lighting is based on PAR, the more PAR the better, a SPYDRx Plus LED average is about 900 umol, the Ushio Hilux 1000w de has a max of 2100 umol. So if you can figure out the PAR of your light, then you can gage it to other lights. HPS - 400w=660umol, 600w=1045umol 1000w=2100umol

 

Sweet, a fellow mainliner, and a simular setup. My manifolded baby's under.

 

They look real good, I won't try to guess the yield, based on what I see, you won't be disappointed.

 

PAR meters are pretty expensive, but if you have a way to test the amperage draw from the wall on that light,
You can calculate the TRUE watts of your light from that : Volts X Amps = actual Watts...

You'll prolly find that LED you have is no where near 900 actual Watts...maybe 450,if you're lucky.
Then figure you're actual watts per square foot of grow ...It takes at least 30 (preferably more) watts / sq ft to get a decent yield.With that, You MIGHT get a gram per watt,if all else is going well.

 

I had 11 ounces off 4 uk-cheese autos in 90cmx90cmx180cm under 600w hps

I recon he might might get around a pound

I grew some blueberry last grow. For me they were not heavy yielders. About 3 zips a plant. The smoke was good though. I grew them under a single ended 1000hps. This grow i went with some feminized super silver hazes which seem to be better in yield potential. This is a photo 10 weeks into flower on super silvers. Hope u have better luck than i did on the blueberry bro.

Hmm idk why people are telling you what you will yeild its based on way to many factors to even give a decent guess
Dont listen to all the master growers here

 

Ive pulled a unit out of a 4x4 space but i have also pulled less
With the same equipment.

 

Thanks bro. I grow organic in soil and usually keep my ph around 6.8. I give them alge meal and bone meal up until the 9th week of flower on an 11 week flower strain. You may want to give them a feeding and see if that helps. Some yellowing i dont get so concerned with. Buds grow in different stages, some weeks they will grow more than others. Even though the super silvers advertise a 11 week flower they may take longer to finish. I usually like my tricombes more of an amber anyways. Some growers say to starve plants at the end but ive never done that and it makes zero sense to me.

Also some lower leaf yellowing isnt a huge deal. Most lower leaves die off in flower as they r useless to the plant now and light doesnt usually penatrate that deep into canopy bro

Indeed man leaves do yellow during the fade tbh once it start its almost impossible to stop here a pic at week 8 in a small 4x8
