Day 18 and a day late if only by a little. Brainstorm is ok, seems bigger to me. Yellowing is down but is gonna need some help. Dropping the Grotek from next feed or two, I believe the high dose of potassium is locking out the Cal/Mag. I'm gonna work on a flush in the morning, it's in the front pot and reachable. The Chunk keeps on chunking, she's been a pretty easy girl. Same two buds on the Brainstorm, good and bad light, top and side. Smoke em if you got em.
Lighting Ceramic Metal Halide

- Start date
The worst and hopefully last of the yellowing on the Brainstorm. Gotta pump the brakes here! Getting back to the light I'm happy with what it's producing so far. Penetration at this wattage (350w) good I suppose. Theres pics of some small stuff under the canopy and under the screen that really don't deserve to look that healthy. I'll chop over a couple weeks while the Chunk finishes long. Buds on the taller stems are running right down to the screen. There is a lot of blue light thrown by this bulb (4200k). Stretch is minimal. Nodes are tight, Buds look stacked. All the "lumber" is getting noticeably thicker.

Data? I'm no scientist, just speaking from personal experience. If you want to buy a 75w LED that costs more than the 315w CDM, go ahead. TaNg is the only person I've seen grow huge plants under the HS1, the other grow journals I've seen were.. well, less than impressive. I didn't even want to like HID lights in the beginning, but how can I not when they kill all the LEDs I've tried.
Good post, interesting perspective.
A few comments
- the running cost, the CDM uses almost 5 times as much electricity as the HS1, 340 W (including ballast) vs 75 W, ok, lets say 2,5 - 3 times as much in real terms due to large coverage area for the CDM. Then there is the yearly cost of CDM bulb replacement, 110 Euro cheapest I have seen vs no HS1 replacement cost.
- The purchase price, at least in Europe, is higher for the CDM than the HS1, App. £450 vs £375....if I haven't lost the knack of finding the best price.... Lol
-Those numbers add up to a significant cost disadvantage for the CDM over say 5 years. I can buy 2 HS1's and still come out with some pennies in my pocket, and more flexibility in light coverage. This of course assuming 2 HS1's is roughly equivalent to 1 CDM, which is not easy nail down from what I have read here and elsewhere. And I have done a fair bit of reading lately..... Lol
Please don't get me wrong, I am just trying to get a meaningful, "objective" and level-headed discussion going about this.
I and about to kit out a 150 x 170 x 240 cm Gorilla tent. So which way to go, all HS1(I have been advised 8 is adequate for 8 plants, better with 12 for more than 8 plants, and the bee's knees with 16 for unlimited botanical frolicking, SCRoG and SoG), or do I mix HS1 and CDM, or go only CDM (say 6 CD's although at a still higher cost than 16 HS1's over 5 years, and using 2 kW vs 1 kW which makes me worry about the lecce meter and what conclusion the power company could jump to when comparing to past usage, let alone having to deal with the extra heat generated, both sumner and winter although for different reasons).....?????
If TaNg, Ganjamoto and a few others can achieve amazing results with the HS1, then it is a matter of others to match their growing skill, because clearly the HS1 is up to some serious business if matched with the right skills and the usual "optimal" environment conditions, temperature, humidity, root aeration and so on.
I am leaning towards a couple of CDM's and HS1 for the balance, perhaps with a partition in between just to see if there is any noticeable difference...
Well, dunno, nothing has been carved in stone just yet, but the Tent arrives next week, so it won't be long before the chisel has to come out.....!!!

The D-Papillon fixture costs 495 euros in Finland and I've used the same 930 bulb for two years non-stop, yields have gone up every round as I learn from mistakes. The 315w is perfect for my old 80x80x150 tent and 4 plants, but it would be enough for a 90x90 area. Sure you'll save electricity with the HS1s, but the amount you need to yield to cover the electricity bill is really low.
I'm starting over in a new place this summer and I'm going to use a 120x90x185 tent with two 315w D-Papillons. I did consider the HS1, but I'd need to yield atleast 300 grams with it, and I don't think I could do that, with the CDM it's easy.
[edit] I've been experimenting with adding LEDs to the CDM mix and I didn't notice much of a difference when I added my 80w hans-panel in the grow area.

Hey Psyphish, thanks for looking in. I've heard two years on these bulbs also. But I really need to think about a spare, just in case. Got a question. What height do you run at from the top? 18-20 inches seems good. As I fill in though, I'm worried about catching a little burn.
I still think about adding light too. It was part of the original plan to pick up the slack in the corners with some low wattage LEDs. I have been surprised at how well it's handling the edges and corners actually.
Adding some UVB to the spectrum interests me more than upping yields. Quality weed remains the focus. I believe UVB, in the right proportion, is the way to go. I've got a pair of 24 inch T5 fluoros I can hang to check heat. If it goes well I'll get the right bulbs.
How far apart is ideal for a pair of LEC315s for even coverage? Two of these angled down on a single big plant would be nice.

OK, what are your yields.......I don't care about g/W/light..... this is a complete misnomer and completely idiotic.........only "Lightsellers" and doofus ignoramus dudes bandy this around...........I calculate in W/g over the grow, including all power used, not just the lights but all other power consuming devices used, dehumidifiers, heaters, air-cons, fans, pumps, etc,. etc.......... after all, everything is inter-related.
Regarding the lifespan of the bulb, 2 years, that is better than what I have seen in grow journals, in fact, there is talk of shifting every 6 months......dunno......only actual PAR measurements would tell........and depending what cycle used/hours used.
Without this information, there is no true comparison possible.

I agree with Corgy, not enough data for an objective comparison.
We'd need to know at least the spectrum curve and par measurements of HS1 and other led products in question.
Waiting for it.
*I'd really love to see King Ganjamoto switch from Plasma to CDM

Pineapple Chunk
Day 20. 420! Smoke em if you gotem! 3 weeks into flower and it’s all good from the captain’s chair. Plants aredoing well. Nutes today. The Chunk's buds have fluffed up, and both plants are in about the same place as far as growth goes.
Brainstorm gets 6 ml Big Bloom, 4ml Grow Big, 4ml Tiger Bloom, 4 ml Cal-Mag, 2 ml Silica Blast, 2 liters wellwater. Skipped the Gro-Tek Monster Bloom here, there’s still a long way to go,and I don’t want to knock too many fan leaves off it too early pushing too hard.
The Pineapple Chunk is taking nuteswell. Light yellowing and a quick recovery last round tells me my levels aregood here. I’ll give it a day to suck up some Cal/Mag and Nitrogen, and hit itwith the Gro-Tek on the next watering if it stays green. 10 ml Big Bloom, 6 mlGrow Big, 6 ml Tiger Bloom, 4 ml Cal-Mag, 2 ml Silica Blast, 2 l well water.
Pics up on the Chunk. Side side topon a center bud. Dropped one end of the screen a row on one side, opening upsome space between the canopy and the light. Buds on the screen moved out and apart. Upward growth seemed a littlestalled, I believe this might grow a few inches to the canopy over the nextweek. Should help my yield a lot. Looks a little crooked, because it is. The other end lays on the pots. Coupleof shots of the popcorn at the screen’s edge. Gonna make a nice second cut.
