I spotted some seed potatoes to harvest at Christmas time. But we didn’t have enough space in the current vegetable. However, one of the previous sets of potatoes really seems to be struggling and I decided to clean one row of these to make way for a new planting of Christmas potatoes.
So the poorly performing potatoes were the Second Earlies – Nadine. The main crop – Golden Wonder – are doing really well. However, just because we have a lot of greenery doesn’t mean that we have a lot of potatoes. But we will have to see. I decided to sacrifice one row of Nadine to make way for a row of Maris Piper.
Having decided that the Nadine potatoes weren’t doing very well, the 5 or 6 plants that I dug up produced quite a few potatoes – all small, but in good condition.
The two sets of potatoes seem to be doing well and I reckon the first crop (Golden Wonder) should be ready by Mid August – if the estimate of 16 weeks is anything to go by! They have been in the ground for 10 weeks now. I couldn’t really have planted them any earlier because of the frost. There’s lots of green growth above ground, but I wonder how much growth there is underground!
The other set (Nadine) seem to be quite a bit behind the first crop. This is a bit surprising as both were planted at the same time and they should take the same about of time to mature.
In hindsight, I think the potatoes plants were probably planted too close together. Re-reading the guidance – they should be 12 inches apart and 30 inches between the rows. Next year I think it should be one variety in this plot with three rows of better spaced plants.
The space to the right in the photo is occupied by some beetroot plants (variety: Bolthardy). I sowed them originally in pots in the greenhouse and put them into this spare space above a week ago. some of the plants looked a bit sorry for themselves when first transplanted, but it looks like all but two will survive.
Looks like I was a little optimistic about the WiFi in the house reaching the greenhouse! Although my iPhone was showing 1 bar on the house WiFi, the Ubibot sensor could only hold onto the signal for about an hour or so. Clearly, the WiFi from the house was at it’s limit. Time to invest in an outdoor WiFi access point!
I updated our internal WiFi access points (we have 3) in the house last year to TP-Link EAP225. There are three of them in different parts of the house. These were installed about a year ago and we have been pleased with the performance. See here. However, they do need to be rebooted every 2-3 months. After this period, they don’t appear to be able to hold a connection for any significant period of time. I have the latest firmware installed on them, but this hasn’t fixed the problem. Rebooting them does the trick! Maybe a future update will fix this issue.
I decided to use the outdoor version of the new WiFi access points that we are using inside the house. The first unit arrived quickly from Amazon. Unfortunately, it was DOA and had to be returned – the green light on the POE injector went out every time that the EAP was plugged in. Not good. I tried different cables. I even tried different POE injectors. Same result. Like a flat tyre that I put on three different wheels. It was still flat!
The replacement unit arrived next day.
I think longer term the right place to install this unit is actually in the greenhouse itself. This will keep it out of the worst of the weather and I have a conduit installed to the greenhouse. It should be straightforward to run an Ethernet cable out to the unit and power it using POE. But for now, I am just going to install it temporarily to see how well it performs.
We installed a new Robinson’s greenhouse a few weeks ago. It is a 14ft x 8ft Robinson Rushmoor greenhouse. This one is aluminimum and powder coated to a pastel green (I think they call it “sage”!). It matches the window frames on the house. It was ordered last November and it arrived at the end of February. It replaces the polytunnel that we set up when we first moved in.
Working out where to site the greenhouse was reasonably straightforward since we didn’t have many options. And none of them were particularly flat. We had to take down an old dry stone wall (to the right in the picture below) and the new greenhouse will now form part of the field boundary. To get things relatively level, we dug some foundations and then brought up some blockwork on the one sided (to the left in the picture below). Then the small dwarf wall was built on top of the blockwork.
The dwarf wall could have been single or double skin (i.e. one or two rows of bricks). We opted for a double width wall. Having seen the price of bricks, I wish we had opted for the single skinned version! All the groundwork took is 3 weeks to complete. Just in time for the fitter to work his magic on the greenhouse. It took a professional fitter 2.5 full days to install this greenhouse – I hate to think how long it would have taken me to do it!
I installed the polytunnel in April/May 2013. It was definitely starting to show signs of it’s age. To be fair, the plastic covering is designed to be replaced every 5 years, so we have done well that I lasted 8 years. The raised beds had also started to rot away. These were the original ones that had come from Tommy Topsoil.
Recently we had been using the polytunnel to house the chickens. They had to be kept indoors due to the outbreak of bird flu in the UK.
The space left by the polytunnel is now being used as a vegetable patch!
Having just installed a new greenhouse, we thought it might be a good idea to monitor the temperature in greenhouse. You would think that there are lots of solutions out there. Nothing complicated. Just a display in the house showing the current temperature in the greenhouse, plus maximum and minimum. Maybe a graph. And connected wireless somehow.
There must be loads around. Let’s look on Google! MMMmm. I must be searching on the wrong terms. Where are they?
The closest I could find is a solution from a company called Ubibot. You will find them here: Ubibot.com. They produce a variety of WiFi environmental sensors for industrial and commercial use. I bought one of their cheaper sensors (WS1) for £78 on Amazon just to see if I can get it to work. Ubibot have a store page on Amazon. You will find it here. The WS1 sensor measures temperature, humidity and light levels. More than a enough for a greenhouse!
According to the blurb that comes with the device, 2xAA batteries will power the device for 4-6 months based on readings that are taken every 15 mins. The device connects to the internet via WiFi and the data is stored in Ubibot’s cloud based platform. There is no subscription fee and it is free to use within certain usage limits. It is clearly designed for much larger scale use and I doubt that one sensor in a greenhouse is ever going to reach the limits of the free account.
The main challenge with this device is setting it up. Obviously with a device at this price point, it has a pretty limited user interface and this can be a challenge when setting it up. Combine this with some fairly scant instructions and if it doesn’t all go to plan first time, then you can be in trouble. This happened to me as something went wrong when I was trying to connect it to me home WiFi. I was trying to do this using my iPhone and connecting to the devices on WiFi network. Somehow, it all went wrong. Even though I had followed the instructions. I reverted to the PC based pages. That didn’t help either.
I finally cracked it by using Ubibot’s PC offline tools. You can download them from here. There was the briefest of mentions of it in some of the Ubibot support pages. It allows you to connect to the device using the micro USB port and set it up without connecting to it via WiFi. You have to download some software from the Ubibot site (the install was a little quirky!), but it was a cinch to set up via this route. I wish I had tried this in the first place as it would have saved so much time! It was much easier than trying to connect to it via WiFi.
Once set up, it connected to my home WiFi network and started posting measurements every 15 minutes! The device (and it’s measurements) appear on the Ubibot data warehousing pages. The main screen shows the latest readings and clicking on the device opens up a set of historical graphs. Wow!
The good stuff
Even though my iPhone was showing only one bar on my WiFi, the WS1 has connected to our WiFi in the house. I am guessing that it is 20m to the greenhouse through a number of thick masonry walls. The WS1 only supports 2.4G WiFi and not 5G WiFi so it is more susceptible to physical obstructions between the access point and the sensor.
Now the data from the WS1 is on the Ubibot platform, I can set up a number of alerts (e.g. sending an email) if some of the data readings reach particular limits. There are some really cool options here. Most of them totally OTT for a greenhouse!
Now the data is on the internet, it is possible to view it from anywhere or even share the data with others. Just on the off-chance that someone wants to know the temperature in your greenhouse!
It integrates with Alexa too! You need to add Ubibot as a skill to Alexa. Just follow the instructions here then you can say “Alexa, what is the temperature of the Greenhouse?” It took me a couple of minutes to set this up. I wasn’t sure how useful this feature might be – either way, it makes a cool demo!
I have had a bit of a nightmare with WordPress for the last few weeks. It seems that an automatic update at the end of last year didn’t work as it should have and a number of the core WordPress files were missed out during the update. The result was the blog went offline and should did the admin dashboard! I had no way of getting into it to fix it!
Here’s the error message I was getting: “PHP Fatal error: Cannot redeclare _wp_register_meta_args_whitelist() (previously declared in /home/j6yrsllk82zz/public_html/blog/wp-includes/meta.php:1394) in /home/j6yrsllk82zz/public_html/blog/wp-includes/deprecated.php on line 4060”.
So today was spent getting things back up and running. Fortunately, it seems to be back working
The fix entailed:
Background reading on what to do and how. Unfortunately, I am not a WordPress expert;
Backing up all of the content and the database for my blog (I didn’t want to lose any content);
Installing a new clean set of WordPress files and overwriting any old ones that might have got corrupted previously;
Now we are back up and running. We are on the latest version of WordPress (5.7) and I everything looks like it is working as it should. I haven’t had chance to check all the pages, but it looks like there isn’t anything missing. And the good news is that the content is backed up too! All 2.3Gb of it!
There is a good article here on what to do if you need to manually install WordPress: https://wordpress.org/support/article/updating-wordpress. I also found this video helpful too: https://youtu.be/5UH7F_tGyRs
