Very interesting @InternationalBeanSmuggler, can't wait to see how the mutant turns out
From 1 light I think dialled you could expect to get 5-7oz with the right strain/s from that space and head room, given your actual wattage from the mars300s is around 150, that would equate to 5oz=140grams/150watts=0.93gpw
The yield is limited by the size and headroom of your tent so by adding more light you will likely see a drop in your gpw which will accelerate the more light you add.
1 light 50z=0.93gram per watt
2 light 7oz=196g/300w= 0.65gpw
3 lights 8oz=224g/450w= 0.5gpw
The above calculations demonstrate the diminishing returns from adding more light cause by your limiting factor, in this case the grow space.
Having said that, if you can cool the grow effectively you will get some super dense buds from that kind of wattage!
thats super fkg cool @InternationalBeanSmuggler hope you get twice as much bud
Looking good @InternationalBeanSmuggler ! btw this is/was the 420th thread on the site by the looks!!!! ￼￼￼￼
Oh WOW great ! I also repositioned my tent right underneath the window. The temp outside is about 5 degs . I can open the window and vent straight out with a 50 cm hose. Do you think i can lower temps with a fan also next to the window and get 3 x 300W in there ? I think i can keep temps to 27 degs with 900W LED... !
What your reckon ?
Also for your interest its possible to squeeze 8 x 3 Gallon pots in there !
I'd be inclined to stick with 2 lights then you'd have 1 light over each set of 4 pots and pretty close too
That's also 600w/300w actual over 6sq foot which is bang on 50w p/sqft which is spot on for large bud growth. I've had extremely large buds (leg sized) from 37.5w/sq ft with 600hps's. So at 50w/sq ft you're golden.
I don't think there's any benefit in the extra spend on the additional light as you're already where you want to be with the 2 lights and that means you've got more money for different exciting seed varieties
Any update @InternationalBeanSmuggler ? How's the mutant getting on?
Looking good, excellent that they all popped!
It's going to be super bright with the 3 x 300s in there!!!! Can't wait to see it all rigged up
I will rig the 3 x 300W fully to the top. The temps are so cool im looking forward to what will happen with yield - and nug density.
They seem to love the bags / pots !
Those watts per sq foot are going to be insane, this is going to be an awesome grow to follow!
Any ideas of how to rig my system with the carbon filter ? I was thinking about can bolted straight on the fan sucking air out 50 cm of hose straight out the window.Maybe i can better use cool air drawn in ?
A moment of insanity , i want 10 zips ! I ordered another 300 w ! Thats 4 x 300 w now !
With the space limitations you need to run your vent from the extraction hole to your fan which will blow air through your carbon filter into the room (you can mount the fan directly on top of the filter with duct tape), so you'll be sucking air out via the duct and pushing it through the carbon in this case
Ok but no way to bring cool air in?
If your sucking air out to the can you could then run a passive intake to the window with ductings. So air would come in from the outside sucked through the cab and out to the can
thanks .What are your thoughts on how to use 4 x 300 W LED and expected yield ?
I'd take a wild guess at somewhere in the region of .4-.5gpw if you can control the heat
That's allot of light and too much light will kill your plants.. are you planning on growing 1200 watts of LED worth of plants, that's allot of tables full...
Have you watched this video before?? it explains how to use the light so you don't kill your plants.
Welcome to FC @m8ty good info
