Graytail's Cupwinners in High Brix Soil - 4x4 - 600W HPS - Perpetual

Gives me an idea. I'm gonna reveg one of the popular strains I have flowering and just give the clones out. I get reps and when they are all small outdoors, I can do the troll face while I grow my regular crops :) Those plants look good gray.
 
Bummer on the no reveg, hopefully can find something to replace it:)
 
I have data on 7 months of harvests now, and I like to crunch numbers, so I thought I'd post my benchmark numbers.

I have a 4x4.75 room with a 600 watt hps

600 watts
19 sqft
1.77 sqm
31.6 watts/sqft

This is a perpetual flower room, so I have an additional space for veg. I average 7.62 plants in the room at any time, for an average of 11 weeks, and I harvest 3 plants a month.

0.69 plants/wk
3.00 plants/mo
7.62 plants/11wks
2.52 oz/plant

The room produces about 1 oz per square foot

1.02 oz/sqft
311 grams/sm
0.91 grams/watt

A guy can do pretty well with only 31 watts per square foot of hps, if he keeps his canopy shallow and encloses the space for reflection. I wonder how much more I'd get if I added another 200 watts of LED. :cheesygrinsmiley:
 
I hear ya PeeJay and you know I love my Top Leds but was tempted myself but decided I was getting ready to get in trouble if I didn't stop spending money..... Seems I have been given some what of a stern talking to about that particular subject so I have been put on a green budget... He wasn't terribly unreasonable but I will have to save for a few months and behave in the mean time which seems to be the hard part for me.......:circle-of-love:
 
Jamaican Dream4 is dried and jarred and produced 81 grams, 2.86oz in 186 days = 0.436 grams per day. In fairness, this plant sat stalled in veg for an extra 2 months. Its sister clone produced a mere gram more, so this is really in the 0.7+ range, too. :cheesygrinsmiley:

I posted my suggestion for a long narrow LED panel to Sara, so maybe we can convince the TopLED factory to make some. Like 100 watt outriggers for a HID - 30 inches long.

NNNIIICCCEEE number crunching!! Those are some great figures that anyone would be proud of considering all the parameters:bravo:

Adding extra would no doubt get you some extra...but whats holding you back from switching to all LED?? just curious??

Thanks! I'm kinda impressed myself. :cheesygrinsmiley:

I don't really want to spend $600 to go all LED. I'm thinking of all sorts of configurations. I'd like to try a 400 watt Ceramic Metal Halide for instance. A ballast and bulb would run a little over $100 and that'd give me 1000 watts - all the light I could ever need and a nice complimentary spectrum to my hps. Or I could add 200 watts of LED for about $200. Or go all LED for $600 ...
 
true true the only thing IMO that made me switch to LED (other than taking away my heat issue) was the fact that i have a 600 and 1000w hps. i last bought a hortilux bulb for 120.00 and i would buy one every few months and thats just the 600w bulb.

so figuring the yield diff is minor, the heat issues are gone and you save possibly thousands of dollars over the life of an LED vs HPS in bulb prices and electricity cost.

now obviously there is the up front cost to get over but if thats your only concern id save up for the LED....BBBUUUTTT what i say and think dont mean much just wanted to give my 2 cents :Namaste:

to each their own, what ever you do ill be happily watching and following along for the journey:peace:
 
The outrigger concept might sell... That wonky light McLoadie was using came out with a red spectrum outrigger, as I recall. The energy saving would pay off the investment eventually. If you add a single LED to the tent to run along the HPS it would add flexibility down the line. Then if you decide to go all LED you'd just buy a second unit down the road to replace the HPS. An out-rigger wouldn't necessarily chain you to the HPS down the road but slapping two comperable LED units would be easier than dealing with one unit and two out-riggers if you went all LED in the future.

I like the outrigger config mostly because of the footprint of the hps. Mine is a horizontal with the flimsy reflector, and that config puts out a sort of rectangular footprint, in a counterintuitive pattern. It actually puts out more light perpendicular to the tube - the ends don't have much intensity. So, I'd like to fill in the ends with a strip of LED down each side, perpendicular to the hps bulb, in a H-config, if I've described it properly. It would seem to me that every square space has this issue, and a 30 inch 100 watt panel would be perfect to mix with a horizontal HID. I've also seen a fabulous sealed vented reflector for a vertical bulb for about $150. That would solve the footprint issue, too, and also significantly boost the reflective power of my 600 watt hps. Lots of possibilities. :cheesygrinsmiley:

I hear ya. Cudos for thinking "outside of the box."

The long thin shape is also great for a veg cabinet. TopLED claims a 28" x 28" footprint for the 48x3. My 72x3 would be about 20" x 46" footprint at 100 watts draw- perfect for a cabinet!
 
I'm just a micro-grower with a 24" x 18" flower space. The hardest thing about LED shopping is maximizing watts for fixture dimensions. I want a loaded light with a 20"x13" fixture!

And haillll, I already grow more than I smoke. Whenever I think I should spend more on lights that realization grounds me. It's fun to window shop, however....

Ya ... been there ... doing that ... ! :rofl::ganjamon:

It's just that, if I can get 3 zs, um, why not 4? Or, they could be prettier and stickier, but ...

... ya ... :hmmmm::rollingeyes:
 
Heheh, I spent 2 1/2 hours this afternoon manicuring SLH Reveg ... whew!

But oh my, this may be my biggest harvest yet - maybe 4+ oz. Every branch, and there were 30+, had nugs all the way down. Wow. And even the lowest buds had big fat trich-covered calyxes.

And the scissor hash was stellar! :bongrip:

SLH Reveg - 278 days old - 80 days 12/12 - 70 since pistils - brix 16/16
