the Sil tent has collected the hodge podge


Afgani x Azad pollen put down on two mels punch on the far right (one out of frame on left) , Two un pollinated stunted Ortega's inset right & a pollinated Ortega pollinated with a male Ortega
(L) . That rounds out the passenger manifest at the moment.

if you have 1 plant and 1 3x3 tent and a capability of 500w SiL....
what's the highest yielding method?

3x3x6? If i was trying to break a record I would grow the plant vertically up one side of the tent, keeping it flat as possible with a rigid trellis, and put many hours into training the plant to fill the entire wall. Maybe build a tall (5.5x3'?)SIL fixture with 9w bulbs sitting against the other side aiming towards it. Or just lay the tent over on its side and scrog the plant wide as possible, a SOG would work better that way probably. Considering how close people keep there SILs it seems like a waste of head room if you have a tall tent not to. It would roughly double your sq footage and harvest.


Good growers have hit 18 or even over 20 zips in a 3x3 using HID, with good canopy management and genetics.

I dont use tents but if i had a 4x4 or 5x5 i would lay it down, add a few vertical supports to the poles, and hang lightweight lower wattage SILs from the wall and treat it like the ceiling.

Tents are designed for HID with their height. Even better yet I would just use a gorilla tent with the ceiling extension and put a shelf in the middle.

This is one of the advantages of SILs is it not?

Running vertical works, but you’d do far better doubling your total grow space. You’re right, tall tents are for big lights - use the wasted space that big, hot, traditional lights cannot.
Blynx and others have shown excellent results with scrog, so why not install a shelf/rack system, divide your tent into two 3x3x3 flowering spaces (upper and lower) and run dual scrog canopies stacked on top of each other.

Heck, the heat coming off the lower canopy would gently warm the roots of the upper and probably promote better growth in the upper plant’s canopy.

Say the tent is a meter. You could grow a plant dead center, a full meter in diameter. A circumference of 3 meters. This could occupy 1.5 meters of the tents height, giving 4.5 meters in your 1 meter tent.

This would mean putting the lights on the poles. As that is the only gap. The plant would sit within a barrel like cage, perhaps 70cm wide. The trick is to rotate the plant and cage on a turner. So the remarkably close lights are not a problem, and canopy penetration is in another league.

If you at least get your buds out to that cage, you have 3 meters. At 4.5 buds are literally scraping the walls. The real area would be somewhere in the middle.

Looks like 2kg to me..

For sure that would be the best practical way, to just add a center shelf. Could even stagger the upper and lower areas, so your harvesting one or the other every month, instead of both after 2 months..with 8-9wk strains of course. The ability to go perpetual without as much hassle as just 3x3, spread out the amount of work (as in trimming, but the con being bending down and straining your back on the bottom section lol), all while doubling your space.

I only really suggested vertical wall grow being its one plant..

Laying a tent on its side might add more area in a simple way, but at the trade off of taking up more floor space wherever your tent is setup. Personally I would like it as I could setup on a table top and never have to bend over, and have room for storage underneath. Suppose there are always pros and cons to whatever way you do it.




A vertical turn table & circular scrog with only lights in the corners would definitly be crazy. Maximizing the amount of canopy to the max. Suppose you could cut a row of holes in the center of the side walls to externally mount more SILs too.

Kinda reminds me of something I thought of. Lookup my "magnetically levitated plants" thread. Im still waiting for the price to drop on a decent mag lev device, just to play around with and maybe even enter the solo cup competition. i would totally use SILs if I did, rotating the plants into a small vertical row.

fuck me you guys are awesome.

really. the community on here is a poster child for what the community out there should be.....this place is gold, nuff said.

great info from all. i have the equipment for anything at this point concerning SIL, i could literally drape the side of the tent top to bottom, then some.

ive never scrog before but have read about and understand the concept goodly enough, there will be mistakes and learning, but that needs to be minimized to the utmost extent before the show starts. i have deadlines of sorts and need to produce at the height of my capability starting yesterday....that says it.

i have two girls atm that are up for this soon. satori and johnny blazexC99....ive got ample experience in lst/training

getting the pics up, can you hold please?

ill repot these for scrog, and i think the crux of all this will be my screen. here's what i want;

my feeding method is flood and drain those white pots you see. soil mix of various goodies. my nute solution ina big tub, pots go in, all media fully saturated. labor intensive? yes, but the results are phenom. id like to continue that if possible, could submerge a 10gal smartpot if needed and thats where i think im going, but....def. open to new ways.

the problem with flood and drain will be the screen of course. the screen would need be part of the package, the pot......or, a flood/drain system in the tent and leave it all. thats been poked and prodded before but not developed, and i think there's potential there.

and since we're here, any threads that are bona fide on scrog method would be appreciated, i searched and found its gonna take a good bit of time to find the threads i need for info, a head start will help.

thanks again to everyone, SIL is the bomb...thank god/allah/cthulu for alien tech......at least thats what THEY say. explaining SIL to growshop folk is fun, you can see the denial surface on their faces when they grok it :)

You should look into / search for “modular scrog” in the case of large pots, tomato cages with screens stretched over them work great.

I know what you mean about traditional grow shop knowledge (traditional growers as well) when I tell them I expect 1.25-1.5gpw as a minimum/average expectation from SILs and then say “you know, 2.5-3lbs a light” suddenly their expression changes..

Terpene, watching your grows and seeing your results have made a believer of me...new doors swing wide open.

Thank you for the enlightenment... :tiphat:

Basically making a table with legs, with the table top half way up the middle ( a 3 ft tall table). Almost as if you had two smaller 3 ft tall tents that are still 3x3 instead of just one. So like one stacked on top the other, as if you had 2 tents instead of one. Tents dont need to be as tall with SILs because you can scrog the canopy into a flat plane, and keep the bulbs within inches. Then you would have a SIL fixture all the way up on the ceiling, and also one hanging off the bottom of the table top, like having 2 whole grows in a single tent.

If you used plywood as the surface you could ventilate the top and bottom with an extra length of ducking going into the top and bottom ports that are likely un-used. Or use a grid like material for the table top that allows airflow.

If you wanted to you could seal it up around the table/shelf, so there isnt any light leaks, and have a veg chamber instead.
Then have a little extra height for the bloom area and use higher powered SILs in that part, with less training. Just make sure you dont unzip the tent during the 12hr dark cycle..

Or without getting to complicated.. just build a 25 bulb fixture (5 rows of 5), using 14w bulbs, which equals 350 actual watts. Roughly 38-39 watts per sq ft, with room to raise the fixture.

^ like so


Install a scrog net, hit in the ballpark of 1-1.5 gpw , and pull a nice harvest (somewhere between 12.5-18.75 oz's)

i would/just might try it with lower wattage bulbs. i just plain don't favor the hundos without some headroom. too bloody skrong.

Granted, I’m new to this, but wouldn’t a better estimation be to figure watt-equivalent per square foot?

The 14w leds I’m familiar with are 100-watt-equivalent. Packing 25 of them in (apparently) a 9sqft space may give ~38 watts actual, but 277 per square foot equivalent is going to make that grow awfully bright...Is light burn not a factor under these circumstances?
