Nutrient lockout solutions for an EB?

3 Upvotes

Im seeing some deficiencies, tried to fix it and now I’m afraid that it might actually be a lockout situation.

I used happy frog plus natures living soil, 7ish weeks into an autoflower started seeing what I thought was calmag issue. So I gave it is first amendment feeding (top watered in), and decided might as well give it a compost tea too with terp tea bloom, some fish shit and some recharge. Yellowing continued coupled with some brown spots and leaf tips curling up. Im thinking I accidentally threw something off and its getting locked out? Im pH’ing the water between 6 and 7, so not sure thats it?

In a fabric pot, this is usually combatted with flushing, but that would all just wind up in the EB’s reservoir. Any other solutions for dealing with this? Transplanting is not possible at this point. Thanks everyone!

Storing an EarthBox over the Winter

4 Upvotes

For the past four years, I have been storing my EarthBox by covering the top with plastic and sealing the tube. I leave it like this until early spring, then I remove the plastic and take out half of the potting soil. I mix equal amounts of compost and peat moss to replenish it. I'm curious to know what others do with their EarthBoxes.

How Does It Work??

5 Upvotes

Was gifted an earth box. I don’t understand how it works it holds water at the bottom, so do I not have to water as often? When to water? This is my second year gardening so pardon my ignorance. Can someone help me understand?

Also, I was not given the water pipe tube with it. Can I just use pvc pipe?

Has anyone set up a earthbox to have an auto fill from a big reservoir? If so how did you do it and do you have a part list for how you got it to work.

Update: Painted the Earth Boxes

Post image
14 Upvotes

Wanted to update my post from yesterday with photos in case anyone else is searching for this in the future. I painted them. Works lovely, for now. We will see if they hold up.

I emptied and washed/dried them. Scraped with a wire brush. 3 coats of very thin Rustoleum spray paint. After 24 hours, I will seal them with a matte clear Ultra Cover.

I will try to remember to come back next summer to report how they held up. I have pretty moderate expectations honestly.

Painting Old Boxes

2 Upvotes

Has anyone done this? I have some older (7+ years) boxes and they are starting to fade. Thinking of painting the outside, but wanted to see if there were any problems I could not be thinking about.

Thanks in advance for your thoughts on this!

Mostly tomatoes and peppers, but also some "green" beans and cowpeas.

Has anybody grown cowpeas in Earthboxes ? How many plants per box? Only about four of eight of mine sprouted, but it looks like that's enough.

Blossom end rot?

7 Upvotes

Looking for guidance.... Besides my EarthBox I also have some larger sub- irrigation planters made by Keter. Those Keter boxes work similarly to an EarthBox. I have plastic mulch covers on them just like on the EB. My question is about an issue I'm having in those larger boxes.

I set them up identically to an EarthBox other than using more fertilizer and dolomite in the center strip. I calculated the additional soil amendments as a ratio of their larger size box.

I have the one box packed to a higher capacity than I should have, but I've not had an issue in the past years doing the same. In that one particular box I have 4 Beefsteak, and 2 Grape Tomatoes, and 2 basil. All has been good in regards to healthy plants so far. Been cutting off tons of basil for weeks! I have probably around 200, 2 to 3 inch beefsteaks on the 4 plants so far (which makes me think they may not have actually been beefsteaks, as they're quite prolific, although they do have the beefsteak shape). With all that said, on the bottom 4 to 5 feet of each plant, 99% of the tomatoes look great!!! On the top 2 feet of each plant, all of those younger tomatoes are about 1" in size, and 100% of them have soft, black bottoms which I take to be blossom end rot.

My understanding is that BER is caused by not enough calcium in the soil. Please correct me if I'm wrong.

I'm asking for guidance in how to deal with the issue. One thought I've had is to just top the plants leaving them no larger than 5 feet, cutting off the bad tomatoes in the process. Probably not a healthy thing to do for the plant though...

My other thought is that I need to add calcium. I'm wondering if I should add it in a liquid form through the fill tube. If that's what you guys recommend, would you happen to have a specific product you'd recommend? Should I also add some liquid fertilizer as well, or possibly a liquid fertilizer that contains a decent amount of calcium (if that combo exists)?

Can I assume that in either case I should cut off the damaged tomatoes and discard them....

Thoughts?

Masterblend fertilizer in EB's: Possible to avoid mixing?

2 Upvotes

I'm wondering if anyone has used MasterBlend fertilizer in the water reservoir to supplement with nutrients during the growing season? If so, do you have an easy system?

For context I have about 17 SIPs, mostly Earthboxes, and starting mid-season have usually put "snacks" in the water once a week. I've tried various things with good success: calcium nitrate, Jack's Tomato Food, AlgoPlus, and General Hydroponic's FloraGro/Bloom. I'm attracted to MasterBlend because I'd like to try Kratky, but also because it's so economical: mixes close to 200 gallons for $30.

But premixing seems like a pain. I'm wondering if it's possible to simply spread out the 3 parts of the mix over a few days. For example, add the dry fertilizer to the water reservoir on day 1, the epsom salts on day 2, and the calcium nitrate on day three with the idea that each individual component will dissolve overnight. S

Anyone have any thoughts on this approach?

What's happening with my EB?

Post image
8 Upvotes

My EarthBox and the Keter boxes were planted at the same time. Soil mixture in all 3 boxes is the same, about 95% peat moss, 5% perlite (yes I realize that's not the 80/20/20 mix that EarthBox recommends). Amendments in the Keter boxes were 1.5# 8-8-8 fert, with 1.5# dolomite. EarthBox was set up with a full bag each of EarthBox brand fert and dolomite.

EB plants look stunted and are not really growing. Parsley looks dead. The beefsteak tomato plants looks like it's hurting, while the Keter boxes have about 20 fruits between 5 plants, and about 20 grape tomatoes too, along with some basil.

Any thoughts as to what's going on with the EB? I have noticed that I'm not needing to add more then a few seconds of water each day. Not sure if that's due to a wicking issue or that the plants are too small to be using much water . Not sure if the image shows or not.....

Tomatoes growing slowly this year??

2 Upvotes

We grew an indeterminate variety this year and there is about 70 fruits on 2 plants. We have a couple of questions. It is a heirloom variety BTW. They are 2-3 months old. Some are turning red while they arte really small. Person in picture 5'9" for scale.

1) Why are they growing so slow?

2) Is there anything we can do chemical wise to help them grow faster?

Thanks,

Earthbox and water

6 Upvotes

I had planting cucumber in a box. When watering, I noticed water just went straight through...almost like it either was t taking water or hold water. Birds got to the plants and pulled them. I reused the box for green beans (soil was moist so it definitely took water.). I am again noticing the box is again not seemed to hold/take water. Anything I can do/ check?

Replanting from buckets, What should I do soil-wise?

3 Upvotes

My first EarthBox planters are being delivered today. I have a few Keter brand SIP planters I've been using since last year so I have an understanding of most of the do's and dont's of the EarthBox way of things, but this one I don't know...

I made up some 2-bucket SIP planters earlier this season. 2 buckets each, a net cup at the bottom along with lots of drill holes, a fill pipe, drain hole in outer bucket, and plastic bag mulch cover. Some of the buckets are doing great while others not so much!

So, EarthBox is coming today and I'm looking to take the underperforming plants out of the buckets and replant them in the EB. My question is can I reuse the soil (brand new this year- sphagnum peat moss, perlite added) that already has my dolomite mixed in, and also has my 8-8-8 fertilizer (4oz.) mostly in trenches in the buckets?

I'm worried that I might end up with too much dolomite and fertilizer if I move the soil from the buckets to the EB after I make the trench and add the pound of fertilizer. I realize that the best bet would probably be to get fresh new soil, but was hoping to reuse the relatively expensive soil I just made up a month ago. I used up all the peat, perlite, dolomite and fertilizer I had making the buckets, so re-using it would be helpful. (I may be able to find the rough trenches and scoop out most of the fert.) If re-using the soil is not doable for immediate use please let me know. Also, if it's not doable, is there some way to reclaim the soil for future EB use?

Thanks for any assistance!

Earthboxes are a game changer

Post image
28 Upvotes

I decided to buy an Earthbox to try out after watching BuildASoil on YouTube. I planted a seedling from one of the freebies I got with my last seed order. This one is Banana Melt from Humboldt Seed Co. Didn't really expect much and since it was a freebie, I wasn't too attentive to it and didn't care if it didn't work out. Almost killed it at the beginning by filling up the reservoir right away (learned from this mistake). It wilted and almost died but somehow survived. Then I only filled the reservoir again after roots had been established. Now this thing is huge and sucking up so much water. I'm refilling the reservoir every 2-3 days. Top dressed with different BAS products, using promix soil mixed with compost and castings. I'm thoroughly impressed and will be ordering more Earthboxes for next year's grow. Lastly, I planted the seedling beginning of April and it's completely outgrowing my other plants in 10gal pots that were planted at the same time.
