back everyone! I'm ready to go with my newest endeavor! I just finished up my first grow on 
in my BC Northern Lights "Producer" model grow box, and have started up a journal documenting the grow of the clones i took from the Widow in my veg room as well as the seedlings i have sprouted from the seeds that came from the first grow. You can check that in my Sig under Current Journals.
I am very pleased and honoured to be doing this Journal in collaboration with Twilight Groups Ltd., reviewing the Twilight Groups Ltd Classic 165w Full Spectrum LED.
Twilight Groups is a LED company based in China from the research I have done, in the Aquarium and LED grow lights departments and have a wide range of products to suit your needs. From small 15w COB LED grow lights to their 1008w Apollo LED and everything in between.
From the correspondence i have had with their Sales Rep Jason, it is very clear they take customer satisfaction very seriously. They are very courteous and friendly and promptly sent out the lamp once i agreed upon reviewing the product.
I am completely NEW to LED's and the technology behind them. I am doing my best to decipher what all the information means. I am hoping that the Guys over at Twilight will be able to answer all your techie questions you may have. I will do my best to provide you all with whatever information that is available to me.
Here is just a little bit of information, as what is available to me at the moment. i am waiting for some pictures or diagrams as well as some specifications of the LED i am reviewing.
This is the spectrum of light in the Classic 165w LED
200 - 280 nm UVC ultraviolet range which is extremely harmful to plants because it is highly toxic.
280 - 315 nm Includes harmful UVB ultraviolet light which causes plants colors to fade.
315 - 380 nm Range of UVA ultraviolet light which is neither harmful nor beneficial to plant growth.
380 - 400 nm Start of visible light spectrum. Process of chlorophyll absorption begins. UV protected plastics ideally block out any light below this range.
400 - 520 nm This range includes violet, blue, and green bands. Peak absorption by chlorophyll occurs, and a strong influence on photosynthesis. (promotes vegetative growth)
520 - 610 nm This range includes the green, yellow, and orange bands and has less absorption by pigments.
610 - 720 nm This is the red band. Large amount of absorption by chlorophyll occurs, and most significant influence on photosynthesis. (promotes flowering and budding)
720 - 1000 nm There is little absorption by chlorophyll here. Flowering and germination is influenced. At the high end of the band is infrared, which is heat.
1000+ nm Totally infrared range. All energy absorbed at this point is converted to heat.
Twilights prices on their LED grow lights are comparable, if not lower that other LED companies i have seen and researched. Here is a link to their webiste.

I will update as this journal progresses, as well as Twilight Groups Ltd. will also post information in regards to the Classic 165w LED as well as any of their other products.

Is it in Veg or Flower stage? currently germinating
If in Veg... For how long? Seeds are germinating
If in Flower stage... For how long? N/A
Indoor or outdoor? Indoor. 4'x4'x6.5' grow tent
Soil or Hydro? Hydro. Will start in 1.5" rockwool starter cubes, transplanted into 4" pots, then finally into a 5gal DWC with 6" netpot lid
If soil... what is in your mix? N/A
If soil... What size pot? N/A
Size of light? Twilight Groups Classic 165w LED
Is it aircooled? No
Temp of Room/cab? 23-32 degrees
RH of Room/cab?30-65%
PH of media or res? 5.5-6.2
Any Pests ? No
How often are you watering? Hand watering until established root system is visible, then placing into DWC bucket
Type and strength of ferts used? Gen Hydro's 3 part Flora series will be used, starting at 1/2 strength and eventually working up to full strength. Also Gen Hydro's Subculture-M will be used for mycorrhizal supply. In addition, i will be using Botanicare's Cal/Mag Plus, Pure Blend Pro Compost tea, and Aquashield all used at full strength.
So theres the breakdown.
Heres some information about BC Sweet Tooth as per BC Bud Depot's description:
BC Bud Depot - BC Sweet Tooth
The BC Sweet Tooth comes down fast and heavy in 6 to 7 weeks with maximum yields of dense sweet-tasting candy bud. A BC Bud Depot preferred production plant, this indica is preferred by many for speedy yields of medicinal high-grade. The BC Sweet Tooth is great for stimulating the appetite, and also for providing pain relief and relaxation.
Information on BC Sweet Tooth as per Leafly's description:
Developed in British Columbia by BC Bud Depot, BC Sweet tooth is an indica-dominant hybrid known for its quick flowering time and candy taste. A hardy plant, this strain can be grown outdoors where it can flower in under 7 weeks, but it prefers the indoors where it may flower as soon as 6 weeks. The result of a cross with earlier generations of BC Sweet Tooth and classic Sweet Tooth, these sugary flowers are sure to satisfy your craving. The crystalline buds have a strong, sweet smell with a hint of citrus, and users report that this treat satisfies with a long-lasting, potent feeling that hits fast
This grow will document how a single Twilight Classic 165w LED can grow cannabis plants. If the grow requires, i will add additional 165w LED's as needed.
The plants will be grown without any training, however some defoliation may be done throughout the grow to allow the light to penetrate lower branches.
This is my FIRST LED grow.. most likely wont be my last as I'm really liking the temperature inside the tent in the middle of our summer here in BC in my SUPER hot apartment.
Here's some pictures to get us going with the Journal. I'll start with my method of Germination.
The Beans:
My germination mixture:
Aerating the mixture to activate the microbes:
Beans in paper towel:
Beans inside ziplock baggie:
And their final home to Germinate, on top of my ps3:
And thats where we are at right now
Thanks for everyone who follows this along, and a HUGE
to Twilight Groups Ltd, cause without them, this couldn't be happening.Check the link above for their products, and send them a PM on here if you are interested in buying some of their products.
Stay Medicated friends!
