Grow Box Recommendations for next Strains to Test

Hi guys, new to the forum here (well new to posting, not to visiting) and looking forward to chatting with some of you.

Looking for some recommendations on the next strains to test in our prototype grow boxes. I'll provide a little background on what we're doing with our grow boxes.

We are working with a few prototype boxes here and the basics are as follows:

1) we don't use tents, we built actual grow boxes - with wheels so that they can easily be moved (they're heavy as shit and wouldn't be easily moveable without wheels)

2) each box can accommodate a single plant up to 60 inches in height.

3) We are currently lighting each grow box with a 400 watt cob light setup - the lighting system is completely automated in movement (motors move the light up/down the grow box so that height of the lighting can easily be set and change with the plant growth) and timing (as in on/off timing). The box will actually detect the highest point of the plant and adjust itself accordingly.

4) The watering system is completely automated. We have multiple soil senors in the box that track the moisture level of the soil - those senors are used to trigger the automated watering system and keep the soil at a specific moisture level. One of the things we are doing is determining the optimal moisture level for plant growth for every strain we put in the box - so the optimal moisture level will change on a plant by plant basis.

5) The nutrient feeding process is also automated. This was is a bit more complicated - it's not automated on the first "run" of planting - because we don't have the data on the soil nutrient levels over it's development. So with every new strain we run weekly soil nutrient tests to determine how much/fast the plant is eating and thus when it requires new nutrients. Every subsequent planting, the system will automatically add the appropriate amount to nutrients based on the previously collected data.

6) The airflow in and exhaust systems are both automated (carbon filter on exhaust).

7) The box also monitors box temperature, humidity and light levels (all sensor data wirelessly uploaded to a database with all these nice little graphs - I mean who doesn't like graphs!). So we literally log every bit of data throughout the grow process - we can tell you what the moisture, lighting, temp, and humidity was at 4:20PM on Friday of whenever if you wanted to know :P

So basically, we go from strain to strain gathering grow data and using that grow data to automate the grow process for a strain. Over the past year, we've done 7 strains and the results have been outstanding (thus far all 'quick to harvest' strains). For all seven of those strains, we can literally direct sow the seed and come back when it's time to harvest (well, we have the system setup to take pictures every week also and send those to us - just in case there is an issue with the plant that the system isn't designed to handle) (and yes, we HAVE done exactly that - it's awesome). As an example, the last strain we finished up with was Emerald Triangle Bubba Cheese Auto. Now we can choose "Emerald Triangle Bubba Cheese Auto" on an LCD and the system configures all the automated systems around the settings we have for that strain.

So what we are looking to do is essentially go strain to strain gathering data and setting up the automated system around each strain. It's a time consuming process but the resulting system is pretty awesome.

Anyways, we were looking for recommendations for the next strains to add to our grow boxes. We prefer to keep the strain testing to auto-flowering strains that are under 60 inches and no more than 10 weeks to harvest. Obviously, strains that require any type of trimming or manual work we aren't really interested in. Thanks ahead of time for any recommendations guys!

Can I ask the actual dimensions of the boxes? Also interested in the specifications of the COB systems.

Sure, internal plant usable dimensions are 36"L x 36"W x 60"H - outside dimensions aren't far off except for on the height as a bit of space is used up with the lighting, venting, plumbing, electronics, etc... and I'm not counting the soil area as "usable" in the dimensions I gave you (so basically the 60"H is from the top of the soil up. The actual soil area is very large for a single plant - 36"L x 36"W x 20"H (so yes, you could grow more than one plant in the box but we're only testing single plants at this time - growing multiple plants per box will throw our data off for what we're doing as it adds too many additional factors to consider).

As far as the COB lighting, are you looking for something specific? ... I mean, typical COB lighting - full spectrum lighting...the 400W spec is the wall pull. We connect it to a gantry that is moved up/down through the use of nema motors and lead screws. We have sensors in the box to detect plant height - which, based on our configurations, will cause the light to move up/down in the box.

Typical COB lighting could mean anything called a COB. Not all COBs are created equally, not by a long shot...Are they prefabricated fixtures, or did your group build the lighting as well? Sounds like a group of very dedicated and ingenuitive minds.
Fascinating project no question, just curious how you determined the lighting source.

Excellent point .... I guess in the scheme of the "market" there is all types of garbage out there being sold. All of our COB LEDs are actually custom but manufactured by a large LED manufacturer in China to our design specs. But you know it's easier to have something manufactured to fit into your design than try to build around what's already out there (I mean, I find it easier at least - but I'm also regularly in China working with manufacturers for clients so maybe for the everyday person they might not find it as easy).

But we didn't just start out with just COB LEDs... we actually tried all the lighting options (and multiple grow boxes contained the same type of lighting but were used in slightly different ways). And using the data being collected by the boxes 24/7 as well as, obviously, the final result - we determined that COB LEDs worked best for us. Don't get me wrong though, we aren't saying that COB LEDs are better than all other lighting options, only that COB LEDs work best for our setup. There are far too many factors involved in setting up a grow environment to conclude one type of lighting is better than another overall, so any such determination must be environmental specific.

So do you have any pictures of your box and the test grows?
Of course we do.

BTW, I'm a fan of your little grow journal - it looks like you put a lot of work into that and those were some nice looking plants. What was the end height of your Gorilla Glue #4 plants?

Those ended up kinda short just under 5 feet. I flipped them too soon. This round should be a lot better.

While we certainly appreciate your reply, I believe our lack of specificity in the request has caused a little confusion. We basically maintain a SB of everything commercially available (and some that aren't) and are very much informed on the traits of all the available strains. Our inquiry was intended to learn about the preferences of growing community within the established criteria. The more popular strains for growers are the ones we wanted to focus on first.

@BinaryTT you may wish to go through the journals section and see what people are growing in there, especially on some of the longer journals.

Thanks for the information on your grow, that would be a little bit taller than what our current information on the strain includes but still within our box capabilities ....so I believe that we'll make it one of the new 7 test strains.

It is a popular strain. Another one I like is Kandy Kush. Purple Punch, Star Dawg, Wedding Cake are some other good ones.

Fair enough but with the 10 week window you stated
("We prefer to keep the strain testing to auto-flowering strains that are under 60 inches and no more than 10 weeks to harvest."), its not an easy task- hence the list.

I've only grown 2 auto's, out of those Fastbuds Blue Dream was the better one but majority of growers stay away from autos.

One day these grow box's will hit the right market at the right time and be successful. Be like the humble home brew kit, but the price has to come down a fair bit.
GL with your endeavour.

There's actually a pretty decent number that meet the criteria but if you don't grow a lot of auto's then I guess you probably wouldn't have any real favorites to suggest :) We'll certainly checkout Blue Dream though. We're actually only going to spend another 6ish months working with autos only and then we're going to start working with non-auto strains as well. There were reasons we started with autos - nothing I'm sure anyone here cares about though. We also plan to double the number of grow boxes this year and increase the height of the new ones to 96" to accommodate larger strains. And we should be a position where we will start using fewer boxes per strain - so we'll be adding strain data to the system pretty quickly starting later this year.

Honestly, the boxes themselves are pretty cheap to build when working directly with manufacturers - less than 1k a box. The software and grow data to automate the systems is where all the real work comes in. We're actually not really doing this to bring a product to market. We're doing it because we can and because no one else has. When we're done with cannabis strains, we'll probably start adding other plants .... one box.... that can grow anything ;P

Thanks and good luck with your future grows!
