Bruce Banner Seeds – Bruce Banner Strain Grow Report

Bruce Banner seeds are available from Dark Horse Genetics. They have embarked on a breeding project to deliver the original cup winning Bruce Banner 3 in seed form. Lineage:OG Kush x Strawberry Diesel

Bruce Banner seeds

I just purchased a pack of Bruce Banner seeds which is labeled as Bruce Banner 2.0 (Bruce Banner BX2). I received 12 seeds and germinated them. The pack says “For souvenir purposes ONLY – Dark Horse Genetics are not to be germinated anywhere.” Luckily I don’t live “anywhere”. I live in Washington. I am happy to say within 48 hours all 12 had cracked and had tails. Here is how I germinate weed seeds:

Bruce Banner Seeds - Bruce Banner Strain Grow

Before I start my grow journal I thought I would share some background info on the Bruce Banner strain. So following is some background info on this strain from their website:

Original Bruce Banner. This is the original cross that created Bruce Banner. Same female. Same male. The outstanding BB3 and BB5 phenos were found in less than a dozen of these seeds. Now these legendary seeds are finally unleashed en masse to the public. Expect outstanding flavor and unrivaled potency and resin production.

Bruce Banner Seeds – Bruce Banner 2.0 Grow Journal

So Bruce Banner 2.0 is making its debut. These seeds are ready to hit the coco!

I decided that I was going to try growing my Bruce Banner seeds in rockwool cubes instead of coco. So after setting the sprouts in coco I removed them and washed the roots clean.

Some roots were fairly long already, even though they were only in cups for 3 days. So there was a bit of transplant shock.

I cut the rockwool in half and put the roots in them and they fit snugly inside the tray. The first leaves are looking crappy but there is new white root growth coming out of the blocks and the next set of leaves look healthy and green. All twelve seedlings should be just fine and the new rooting will help hold the cubes together.

The other group of seeds in the tray are Cookies and Cream from Exotic Genetix at 3 days.

Bruce Banner Seeds 21 Days

Sometimes a grower cant make up his mind! I ended up potting these Bruce Banner seeds back into coco again which probably set them back about a week or so.

I have been having some problems with pythium now that it is warm, and plants seem to better in coco than rockwool. Mostly cleared up from previous grows but there are still a few spores floating around, although I am winning the war.

I just moved these plants under 12/12 lighting so I can sex them. Right now I am short on space and between the Bruce Banner and the Cookies and Cream I am growing I have 24 plants.

I dont like to crowd things so hopefully getting rid of the males will save space. I am not in a hurry to run these so after the males are gone I will reveg them and take cuttings. So here they are at about 21 days. There is 1 runt but overall they dont look bad and they were just fed so they will start greening up.

Bruce Banner Sexed

So after 10 days under 12/12 lighting I was able to sex my Bruce Banner seeds. I have 10 girls which is phenomenal with 12 seeds. It is early still and there is 1 that looks like it could go either way but even if that happens the m/f ratio on these beans was great.

For the most part they are tall and leggy like an OG but there are a few smaller shorter phenos too. I am going to move them back into my veg tent in the next few days and I will take some clones of them too.

Bruce Banner Seeds Day 1 Of Flower

Today is day 1 of flower for my Bruce Banner seeds. These are the original seed plants after going under 12/12 for sexing and then reveg. They were transferred from coco solo cups into 6 inch net pots filled with rockwool croutons.

I have clones taken from these girls so this is basically a shake down run. I think there are 3 basic phenotypes in this mix. A tall OG leaning towards the original Bruce Banner, a medium pheno that leans more towards an OG/ Strawberry Diesel mix and there appears to be a 3rd phenotype that is much smaller than the other 2.

Bruce Banner Seeds Day 1 Of FlowerThey are looking pretty healthy all things considered and this will be their first full day of 12/12 lighting.

I am planning to run them in a modified flood and drain/nft system. My plan is to put them on a spreader mat and cover the plants with panda film.

This will allow the roots to stay dark and moist and grow into the mat. The plants should be able to grow a much larger root mass than in standard or even smart pots and hopefully this will equate to higher yields.

I am waiting for my OG Kush ladies to finish up over the next 2 weeks as they flush. Then these BB girls can have the tray to themselves and I can put the cover on it. Meanwhile I will be hand feeding them at 600 ppm as the others flush.

Bruce Banner Clones

While these seedling girls are in veg I also took clones of them. It’s not unusual for clones to be different than the seed plants they came from so I also take clones from them. These clones rooted for me in 8 days.

Then the seed girls are a shakedown run for me. They help give me an idea which plants are likely to be the best keepers. In this case I have 10 girls and I can only keep 1 or 2 at most if I decide a strain is worth running again. I am pretty sure I will be running Bruce Banner more than once.

Bruce Banner 2.0 Week 1

The Bruce Banner seeds just finished their first week under 12/12 lighting. Some plants are already starting to show preflowers. They are being top fed right now at 600 ppm.

Once the table clears in the next week to 10 days they will be fed with flood and drain with a spreader mat underneath them. The top will be covered with panda film allowing the roots to spread out and grow much more. Here is a couple of pics:

Bruce Banner Flowering Delayed

I have decided to delay flowering these girls. I am concerned because they started flowering before the sized up. Maybe this was a result of putting them in 12/12 to sex them and not giving enough time for them to totally reveg.

So I moved in 2 Gorilla Glue #4 plants that outgrew their veg area instead. If you want to follow that grow it’s at

Meanwhile I am vegging the clones I took from them and they will be going in after the Glue is done. Right now even the clones I took are flowering but hopefully 2 months of veg time should cure that.

Bruce Banner 2.0 Week 1 Flowering For Real This Time

After a long delay by Bruce Banner 2.0 is finally in my grow closet under 12/12 lighting. The clones I took are about 18 to 24 inches tall and stretch on these ladies is supposed to be up to 200%. So I am expecting 6′ tall plants from the taller phenos.

I have 10 girls in my 2×4 flood tray. They are sitting on a spreader mat with a panda film covering. Watering times are 1 minute every 2 hours.

I am using Heavy 16 Bud A&B along with Fire and Humboldts Secret Golden Tree the current pH is 5.8 and ppms are 560.

Lighting is 750w of 3500k COB LEDs and par readings above the plants right now are at about 650 µmol

Here is a video made on day 1 of 12/12:

Bruce Banner 2.0 Day 7 And Flubber From La Plata Labs

The Bruce Banner is at day 7 and already showing several different phenos. Some of the largest plants from seed are much smaller as clones. That is why I like to do a pheno hunt from cuttings. In my experience clones of seed plants can grow quite differently as clones.

There are 10 girls but one is a runt and I dont expect it to do much. One girl #5 is a monster and #1 is looking good too. The rest are shorter and I guess will lean more to the Strawberry Diesel side.

I also brought in a Flubber from La Plata Labs at about day 55. It was overgrown by my OGs and did not get much light so I am sure it is smaller than it should be. It has really nice looking trichome development and looks like it will make some nice bud in spite of all its abuse.

Not too much to show this early except for the Flubber. Here are some pics for you:

Bruce Banner Flowering Already On Day 9

I started to notice preflowers showing on some of my girls on day 8 and today my Bruce Banner #5 pheno has open flowers on day 9 and #1 isn’t far behind. Most of the plants are showing them now but #5 is crushing all the others.

I started to notice some cal/mag deficiency on some of the fan leaves and that is really not unusual with OG strains. They are cal/mag whores. So I added some CaliMagic at 2 ml per gallon.

I have been using Heavy 16 Bud A&B and Fire but not the Prime until now. So I added it too. My mix is much hotter at 850 ppms. I usually aim for about 650 and will probably drop back down in a few weeks.

I also started only feeding at lights on for 1 minute every 3 hours.  I want to see if fewer waterings will encourage more growth in the matting. Here are a few pics taken on day 9:

Bruce Banner 2.0 Day 14

My Bruce Banner continues to grow and flower. Plants look very healthy. I did spot some minor calcium and magnesium deficiency signs on a few of the larger fan leaves. OGs tend to be heavy cal/mag feeders and magnesium is mobile so it is common for plants to move it from lower to upper leaves and buds.

Plants were sprayed with Heavy 16 Foliar which contains calcium and magnesium as well as silica. Very sticky thick stuff that works well especially in veg, but because flowers are now forming I will only use it this one time.

I have trained these plants in a one node and flip style similar to what Jungle Boys do. However my plants are smaller so most only have 2 stems. Everything below the first few inches was removed. The idea is to have most buds above my screen and eliminate pop corn and larf.

I am after Bruce Banner #3 leaners so I believe the pheno hunt will be in the taller plants. The shorter plants will likely be sour diesel leaners and some will be a mix of the two. So I am not that concerned with yield at this point. I want to see bud development, flowering style and smells on the taller plants.

So far my #5 pheno looks like the keeper with #1 close behind. #5 seems to be the heaviest yielder and is the largest plant. Because these are clones from a seed run there is some obvious size differences between phenos.

Bruce Banner Schwazzing/Leaf Stripping Day 21

On day 16 of flower I decided to test out schwazzing or leaf stripping on my Bruce Banner ladies. These girls were flowered using the one node and flip method the Jungle Boys popularized on Instagram.

I have always done some defoliation but this was my first total leaf stripping or schwaz where every leaf with a stem is removed. I did leave 2 or 3 top fan leaves though.

They looked kind of pathetic after stripping but they began to bounce back quickly. More importantly bud size started to increase and leaves began to regenerate.

My Bruce Banner Seeds At 28 Days

So my Bruce Banner 2.0 seeds turned 28 days. They had a major leaf stripping on day 16 and seem to have recovered nicely. There is some height difference between phenos and at 4 weeks stretch should be over.

The tallest ones are the ones I am most interested in because they are more likely to be like the Bruce Banner #3 clone. I am sure they are all fire but at this point I am not interested in the Strawberry Diesel leaners. All I want is a good yielding, dank OG from this run.

I removed the cover from my flood tray because I felt it was keeping the rooms humidity down. With it off my humidity is up 10-15%. So from 25% to 35-40% is right about where I want it. I know those who use VPD like higher humidity but I like it low, especially in flower.


These Bruce Banner girls WERE scwazzed on day 14 and are now at 35 days stacking and getting after it. Getting stinky and frosty. Trying out some Veg+Bloom RO Soft  along with Heavy 16 Prime and Fire. So far so good. Been running this combo for about a week and the girls seem to like it.

Day 42 Guest Appearance Groot From Guardians Of The Garden (Galaxy)

GROOT - GUARDIANS OF THE GARDEN watching over my Bruce Banner

I am a big Guardians of the Galaxy fan so I think part 3 should be called Guardians of the Garden and took the liberty of inviting Groot over to keep an eye on my Bruce Banner girls. He is the Incredible  Hulk as you know but since he’s a guy I think these ladies should be called the Hulkettes. So Groot, meet the Hulkettes.

I have been running the Veg + Bloom along with Heavy 16 Prime and Fire and it seems to make a good combo and plants are responding well to the mix. Currently pH is 5.6 and PPMs are 630.

I have taken the panda film cover off the flood tray which has helped keep the humidity up in my closet.

I also have changed flood times to 5 minutes every 6 hours. I am flooding deeper because the rockwool croutons dont wick water as easily as coco or larger rockwool blocks. I have noticed the longer flood times also flush nutrients out of the spreader mat better and as a result my pH fluctuations have pretty much stopped and stay pretty stable.

Here are some bud shots taken on day 42. Everything is growing well with lots of frost and calyxes are swelling nicely.

Bruce Banner Day 49 With New Millennium Winter Frost

Everything is sizing up and getting frosty. On day 43 I added some Winter Frost from New Millennium. As far as I can tell it’s a bloom booster/bud enhancer/finisher. It is supposed to be added 10 days before flush. It’s hard to tell if it made any difference in bud size or frostiness. It does seem to start the fading process though. I am starting to see fall colors show up. I will run it until day 53 and then start a 10 day flush.

I have 2 phenos I am thinking about keeping. One has the Bruce Banner 3 bud structure and the other looks like a hybrid with buds that are showing more of a diesel influence.

There was a lot of variation between plants because this is a BX and so lots of recessive genes show up. Some are good and some not so good. Some OG leaner plants have small buds and there are some nice strawberry diesel leaners but I am not saving those even though they could turn out to be better smoke it is the OG leaners I am interested in.

Here are a few shots from my 2 keepers taken on day 51. Very nice trichome development on these ladies.
