4 Kessil H350 - 600W HID Comparison; Dinafem seeds

Sparky4u, cheers for the advice - I certainly agree and am not averse to training plants and providing additional support such as mylar sheeting and possibly even side-lighting. Options for training are somewhat limited with chillies however just as a consequence of most varieties producing pendant pods rather than mirasol types, so good penetration is always going to be needed to ensure developing pods get enough light to grow and ripen healthily... I dare say it is a bit more straightforward to assist with strains of mj as your buds are always growing upwards... am very interested in the results of this grow and must say the plants are certainly looking v. healthy so far! Excellent job

The local grow shop tried to talk me out of the LEDs and into the HO T5. I just had to test these for myself. If this project were to fail, I'd try the T5's though. LED = no bulb replacement for years and years. If these work well, that is going to payoff bigtime.

HO T5s have a very long life too. Individual bulbs are user replaceable and cost < $20 per for quality spectrums. Just sayin

3 weeks flowering. I chose new control plants because the yellowing one wasn't a true rep for the HID crowd. You'll see what I mean when you see the HID group. Also, since these are seeds there are short ones and tall ones so I've chosen two control plants from each group.

Overall, they are looking pretty even. If it was cooler the HID plants would be doing better than they are though.

Short ones. LED = left



Tall ones. LED = left



From above, LED = right now



From above, both types in a single shot. LED = right

LED pics



Top view. There isn't much color variation like with the HID.











HID pics - I took less HID pics this time around

I like this, I is scribed!!!!!!!!!!!!!!!!!!!!!!!! Im running 2 600s wit digi ballast an digilux bulbs and i would love to switch when i see some good results.

Great comparison shots......doing us a service...about time we see these kessil's(350) in action.......

Sounds great. Thats a terrible shame this thread in particular was wiped out. Not too many high quality comparisons out there.

Yeah I agree with gastaker...one the few good comparison grows
I can't even like his comment.....fucking sad

I set my homepage in my profile to my photobucket album, all the pics are there. Once I get the final weight I'll repost them all.

wowwe finished already? how many weeks flowering was that?
good grow tho man

The final results are in.

Notes:

I did nothing to increase the yield of this crop. My only goal was to use the exact same environment and nute schedule to see what each light produced. Also I used Biobizz nutes, aka 'great taste, low yield'.

Last, I only trimmed the non-popcorn bud. I'm not including popcorn in the totals.

The full picture set is posted at http://s1255.photobucket.com/albums/hh638/justjim3/

The numbers:

LED 96 grams
HID 143 grams

LED 360W
HID 600W

360W / 600W = 60%

96 / 143 = 67%

Approx HID weight untrimmed - 35 grams
Approx LED weight untrimmed - 21 grams

HID dried




LED dried - much more fluffy than the HID




HID (left jar) & LED (right jar) popcorn - untrimmed




HID & LED trim - except major fan leaves which I pull before hanging




Overall, I am glad that I bought these due to my heat issue. My tent was cooking at 86 degrees with only one HID. No way I could add another without AC. Yes, I could have added a second HID and AC for less than the 4 Kessils, but I really wanted to see these in action.

Now that I own 4, I'll buy two more. In a normal grow, I run 6 plants per light so on the LED side, it would be difficult to run 7 kessils (to make up the full 600 watts) over 6 plants. It works out well to run 6 lights for 6 plants.

So, if you have heat issues, or you do not have money issues, Kessils are a good way to go. If you want to pump out mad weight and can deal with the headaches of HID, go for it!

Thanks for watching.

hell yes. thank you for an awesome show. now just drop a couple grand and throw a Lumigrow ES330 up with the Kessil H350s as side lighting. seriously though, thanks for the comparison. you're methodology is very clean and consistent.
