Found a couple references but is there any guides on cultivating bonsais that you know of MrK'?
Obviously counter intuitive to make them small, so would be nice to get my head around the full set of principles involved ...
Hi ... I am going to read through your journal now.WELCOME TO THE KRIP KEEPERS FROST FEST SPONSORED BY MARS HYDRO!
Welcome everyone to what should be a pretty exciting journal!
Of the plants I've been able to flower since getting my grow back up a little over a year ago, I've kept the four best strains (the "Krip Keepers" ), three of which are some of the frostiest strains I've ever seen. These are IHG's Dolato, Platinum Kush Breath, and Platinum Cake along with Cali Connection's Blackwater.
Well, for this grow, we're gonna flower out all the mothers and we have some new gear to do it with!
Back in 2016, I tried one of the Mars Reflector 144's for a 2' x 4' tent I was using and was so pleased with the light that, when I upgraded to a 4' x 4', I just added another Reflector 144. It worked out perfectly and gave some fantastic results. I've always said that I'm sure there are better LED's available, but the price/performance on the Mars lights is hard to beat.
So, when @SmokeSara asked me if I'd be interested in reviewing their new SP-250, I jumped at the opportunity (although, perhaps too early sorry @420! ).
In order to demo the LED's in their best possible "light" (yeah, pun was intended there! ), Sara also wanted to send a new 4' x 4' Mars Grow Tent since she believes the plants will receive greater PPFD in the Mars tent and Mars advertises 50+% more PAR (though, they really mean "PPFD" ).
I actually like my existing 4' x 4', which is practically new having only been through a few grows, and it was going to be some work to disassemble and set everything back up; but if Sara says I get more PPFD, I'll give it a shot!
(NOTE: Photosynthetic Photon Flux Density (PPFD) is a measurement of how much light that's actually usable for photosynthesis is reaching the plants. )
So, this past weekend, this arrived:
I assembled the tent alone and in just 10 minutes (no directions, but I have done this before! ) , it looked like this:
After about another 15-20 minutes of me wrestling with the outer "skin" (anyone who's assembled any large grow tent knows exactly what I'm referring to! ) plus another 20 minutes of setting up the electric, ventilation & lights, we had this:
Easy-peasy on the assembly and, wow, it sure is bright in there!
The tent is 48" x 48" x 80" with zippered front and (smaller) side doors on both the right and left sides of the tent:
Each side and the back have passive intake vents covered with velcro on the outside to allow adjustment of the airflow:
There are two 3" electrical ports on the back-left side (one higher, one lower):
And, there's a total of six 8" duct ports including two located in the top of the tent and two (one higher, one lower) on each side:
There's also a velcro-covered view port in the front so you can peek in the tent without having to unzip it:
The viewing window does have some mesh screening embedded in the plastic, but it still allows for a good view and decent pic. These two were taken through the view port:
It also comes with a mesh bag that clips on the inside of the tent. I keep the thermometer there so can check temps by looking through the front view port:
And, perhaps the only thing I really don't like about the tent, so far (it's still early so I may decide I like this later, and/or may find more things I don't like! ), is that, instead of a velcro strap that allows you to velcro the door open to the outside of the tent, this just has a non-velcro strap that you tie to another strap on the outside:
Not sure why they didn't use velcro since it would save the work of tying & untying knots every time one needs the door held open.
I'll discuss the lights and plants in more detail in upcoming posts, since this one is getting kinda long, but here are a few shots of one of the lights:
And, here are the five plants we'll be flowering out (there are two Dolatos on the right but only one pictured and the last pic is the Blackwater):
They've been kept as Bonsais and, right now, they're transitioning to @Doc Bud's High Brix Soil. With these nice, mature moms, veg time should be fairly short and we'll be able to flip and start having some real fun soon!
In my opinion ... this light might set the standard for future LED grow lights.MARS SP-250 GROW LIGHTS
We're running two Mars SP-250 LED's in the 4' x 4' tent. At about 245w/each, two should be sufficient, although, I do think three would be "ideal" for the space and would also give some extra redundancy in case one failed.
Aside from running some CFL's for vegging when I first started growing, I haven't run anything that wasn't "blurple" and didn't have multiple fans. It is a real pleasure to be able to see the plants in what's very close to natural light and even better not having all the fans running when the flower tent is just a few feet from my bed!
It uses a large aluminum heat sync to regulate temperature and it doesn't seem to run any hotter than any of the other lights I've run that use multiple fans for cooling.
The coverage also appears to be excellent with no visible shaded areas in the corners or ends!
The SP-250 uses Epistar SMD chips which can take higher currents, put out more lumens, and have better thermal dissipation than their predecessors.
FWIW, when I was first researching the light, I did notice great reviews (like 100% at 5-stars!) on several third-party LED distributor sites.
Here's are some manufacturer's pics of the SP-250:
Here's the PPFD and coverage at various distances above the canopy:
And, here's the spectrum chart:
There are no separate modes for veg and bloom, so you run the full spectrum through the entire grow.
At only $249 from their website, it appears to be a lot of light for the money and I'm looking forward to seeing how they perform.
Wow! I hope I get those results with the TSL 2000!THE STRAINS
So, let's get into some detail on these strains...
CALI CONNECTION BLACKWATER
Blackwater is a cross between Mendo Purps x Tahoe OG S1 (OR Mendo Purps x SFV OG for regular seeds) that took 3rd place for "Best Indica" at the 2014 High Times Medical Cup in Los Angeles. It averages 20% THC and is known for some dark purple buds. It has a flowering time of 8-9 weeks.
The goal, when breeding Blackwater, was to create one of the darkest OG Kush strains available. The buds from my grow didn't turn dark (I can probably get them to turn by lowering temps!), but they were huge, dense, and covered with trichomes and cured to a nice grape smell. The colas produced the biggest buds I've ever grown with some individual buds weighing over a half and ounce. This, to date, has been the preferred strain to help my Dad with pain.
Here are some of those huge colas & buds from my last Blackwater grow:
INHOUSE GENETICS DOLATO
Dolato is a 70% indica/30% sativa cross between Gelato #41 and the NorCal cut of Dosido that boasts an average 26% THC ratio (22%-29%). Flowering time is also 8-9 weeks. I've heard the flavors described as earthy, musky & piney, but my cured Dolato buds smell just like chocolate, to me! And, while I haven't had mine tested, judging by the trichomes from the last grow, I'm thinking it should be towards the HIGH end of the THC range!
Here's some Dolato colas at only 22 days of 12/12:
By Day #37 of 12/12, they looked like this:
And, on Day #60:
Dried & Cured Dolato Buds:
INHOUSE GENETICS PLATINUM KUSH BREATH
Platinum Kush Breath is a cross between OGKB V2.1 x Platinum with a 60-75 day flower time. These are also incredibly frosty buds and my cured buds smell like sour oranges. The branches on this one were pretty spindly and most had to be supported with yo-yo's to keep them from collapsing under the weight of the buds.
Here are some pics from the last Platinum Kush Breath grow on Day #26 of 12/12:
By Day #35 of 12/12, we had this:
Here's Day #59 of 12/12:
And, by Day #70, right before harvest, they turned a great color!:
This was the PKB sample/tester bud I took:
INHOUSE GENETICS PLATINUM CAKE
Platinum Cake is a cross between Wedding Cake x Platinum and also has a 60-75 day average flower time. As frosty and tasty as the other three strains are, I'd have to place this one as the top strain I've ever grown. The one PCake plant I harvested was put into the flower cabinet at the last minute to replace another plant that turned out to be male (from feminized seed!) so it didn't have much of a veg period. There was a lot of stretch and some wide internode distances, so she didn't yield as much as I would have liked and will need some good training to really produce. But, what she produces is just incredibly beautiful, dense buds completely covered in trichomes with just about every leaf on the plant also covered in trichomes. The buds are still curing on this one, so I don't have a great description of the smell or flavor yet, but it's a skunky/floral smell right now. The trichome coverage on these buds was ridiculous and I'm going to be growing a lot more of this strain and will be using her for some breeding.
Here are some pics from my last Platinum Cake Grow:
Day #30 of 12/12:
And dried buds (still curing):
It's worth noting that all the buds above, with the exception of the Platinum Cake, were grown under Mars Reflector 144's and all were grown using @Doc Bud's High Brix kit.
Let's see how the SP-250's do!
Perfect ... I was looking for that link!This article was originally written by OG member Oldtimer1, I take no credit for this, except for finding and sharing the information with you guys.

There is IR in our light, but uv no, LED can only do uva , which is not very good for plants' growth, uvb is good for plants growth, but plants don't need too much of it. and since white is a mix of all spectrum, so we didn't add the uvb specially. but from the spectrum test report, you can also see a little bit of uv light there.In my opinion ... this light might set the standard for future LED grow lights.
Are you able to test its IR or UV capabilities it professes to have?
