Photoperiod Bud's Shed - First Test Grow

Brief update ...

Main growroom:

Loving-it!.jpg


Struggling with temps in there though ... 30C without any additional heating.
It has been balmy outside tho' ... 10C in January? Huh? ... actually looking forward to the next cold-spell.
They've been on an 18/6 schedule for the last few days, I think tomorrow I'll switch to 12/12 ... they're going nuts growth-wise at the moment, I need to get them started on flowering.

Started my 'mainlining' training on the remaining four today:

Wish me luck with this one ... I'll be well chuffed if it all works out ok.
 
oh yeah the mainlining worked a treat on my somangos.

Ooh. Somango.
I love Jack Herer and I love fruity. It's even got some of my lovely Super Skunk in it. Where do I sign? :thumbsup:
Not one for outdoors UK though, 9-10 weeks flowering could be a bridge too far.
The auto sounds like a good punt though ...
 
A quickie before I go to bed, and I still remember, and I'm still willing to admit it ...

I fucked up.
I didn't research the Fungi thing enough ...

From the RHS website ...

Phosphorus is often in very short supply in natural soils. When phosphorus is present in insoluble forms it would require a vast root system for a plant to meet its phosphorus requirements unaided. It is therefore thought that mycorrhizas are crucial in gathering this element in uncultivated soils. Phosphorus-rich fertilisers are widely used in cultivated ground and not only reduce the need for this activity but are thought to actually suppress the mycorrhizas. For this reason it is best not to use phosphorous rich fertilisers in conjunction with mycorrhizal fungi.

Hmmm. Phosphorous-rich. That'll be bat guano then. Shit. Or not to shit. (Hamlet, revised!).

Looks good for guerilla-growing though ...
Oh dear, I feel such a tit ... it was my 'secret weapon' too.

I'm not giving up though, as I bought a shit-load, so this summer ... secret weapon unleashed, take 2.

:oops1:
 
Sorry, can't help myself .. another update.

Thought I'd show you the amount of space I have to play with for the grow .. plenty of height and width, with room to work too.

I was looking at the plants today thinking to myself I should start doing some early training .. so the first one to get it, top left in all the pics, found herself on the receiving end of a bloody good supercrop this morning, all four of the dominant tops rising up got bent outwards at 90 deg to each other ..

This one's getting the same treatment, but she doesn't know it yet..!

I'll also build a bamboo 'cage' tomorrow, a sort of scrog net but not so 'tight' if you get me? I've got some Iso on order, should also arrive tomorrow, so I'll be well-busy making qwiso and building my cage all day .. just wish I could be wearing flip-flops as opposed to fucking snow boots!

Not quite sure the FIM'ing went quite to plan .. one seems to have taken to it, although I'm not sure ..

Good-FIM.jpg


The other, well, she appears to be doing her own thing ..

Not-so-good-FIM.jpg


Programmable timers .. word of advice, buy two. :thumbsup:
If you've ever tried to program one, you'll understand. If I want to totally change the timing regime for a device (in my case the ventilation fans) I have to completely reprogramme the bloody timer .. and back again if circumstances necessitate a revert. Takes ages and it's painful.

I've found that, due to the fluctuating weather conditions outside the shed, I need more than a 'one size fits all' solution. So I've set up two .. switching between them is as easy as moving the plug..! Ideally, I'd like a whole bank of them ..

Timers.jpg


I'm still tweaking by the day ... lots of permutations to get through! :wall:
I also had to remove the plug for the growroom 'work' light (the one on the far left) .. I kept leaving it on by mistake last week, so now I'm into the flowering stage I can't afford to go and make that mistake again, so it's been removed from temptation, for now.

A couple of handy tips regarding Plagron Batmix soil and Airpots ..

I'm using 20 litre Airpots and I got to pondering the amounts of water I'd need throughout the grow, starting with the first watering.

I gave each pot 2 litres of water when I potted into them, that's all. I'd rather give them less than more at the moment, the soil's already supplied at a perfect moisture-level, why ruin it with more water? I had no run-off, and there's plenty of moisture for the roots without turning it into a bog. Why no run-off? Well, all the nutrients are in the (expensive) soil, not the water, and I want all the immediately-available soluble nutrients to find their way into the plant, not down the drain. Run-off would be a waste at this stage. The instructions on the side of the bag and on the website recommend you flush the soil before using, to avoid too much soluble readily-available nutrient to batter the plant on it's arrival .. however, a couple of UK growers who use the soil regularly told me not to flush, just whack 'em straight in, as the plants are more than a few weeks old and can take it. They were right, there was very little transplant shock and they certainly don't look like they're suffering from nutrient-burn to me.

Also, new to Airpots, I was quick to learn how to water too .. if you water the sides, it all runs out of the holes, but if you water the centre of the pot right at the plant stump, you won't lose any out of the sides, and it'll seep through to the soil at the edges of the pot in it's own time. Seems to be working so far, haven't wasted a drop yet..!

That's me done for now .. have a chillaxing weekend, I'll be a bit busy meself ..! :salute:
 
Well, the bloody Iso didn't arrive, still at the depot according to the tracking info.
Still, I kept myself busy ...

Top left recovered fast, so top right got the same today...

I didn't need to use the shipping pallet in the end, because the airpots have about a 3" space between the floor and the inside pot-bottom, but I'm glad I did because it's made a useful base from which to build my framework.
Simple bamboo canes and plastic ties, cheap and easy.
The plan is to train the plants to fill out that rectangular shape, maximise the light available .. the lighting rig has at least another 20" or so left available to be raised, so I'm not worried too much about height restrictions .. a luxury methinks, and one I intend to exploit. The thought did occur to me though to fit a scrog net, but I've started the 12/12 phase now and I want these finished asap so I can get the other 4 mainlined ones in there ... then I'll most likely use a scrog net, really looking forward to seeing how all these new techniques I'm learning turn out..!

:smoking:
 
When you grow out the mainline plants make sure the terminal buds are never occluded by fan leaves. That happened with one side of one of mine and now they are as short as the secondary branches in the others. Only two days and they had a height difference of 10cm that's not going to grow out anymore.
 
Gotcha @Druid .. thanks for that.
Two days is a feckin' plant-lifetime in this game, it can take 3 months to grow one, but only half-a-day to kill one! ... :naughtystep:
 
Update, I've been busy again ..

First off, I thought it was about time I conducted a proper water test, so armed with my new pH pen and some samples, I got testing ..

Water-test.jpg


From left to right, De-Ionised water (labelled, neutral), de-humidifier water (blue cap), rain water (red cap) and tap water (glass). I calibrated the pen first, and used the laser thermometer to check that all the temps of the fluids were the same .. I left the samples in the room to stabilise for half a day so the results would be as accurate as possible.

And they were rather surprising.
Most of all was the de-humidifier water, that came in at pH 5.59 .. so that's only getting used as a pH-down agent, if at all!
The tap water was lower than the water-authority-published data, at pH 7.25 (they had it at 7.8), but still too alkaline.
The rain water looks like the one .. pH 6.27 .. kerching! And it's free. And I don't have to lug it up the garden to the shed either.

Now, downside, it does contain traces of carbonic acid (CO2 absorbed by the rain in the upper atmosphere) and whatever else the industrial age has chucked at it, and it's lacking in trace elements needed by the plants so I'll have to supply those myself. I'm using seaweed extract as a foliar spray and a root feed, along with cal-mag supplement at the moment, the soil should take care of the rest.

Seems to be working well so far, this is after the first week of flowering ..

Anyway, those are cooking nicely, so ...

... meanwhile back in the vegging chamber, the mainliners were looking like they were ready for phase 2:

Mainline-#1---top---pre-phase-2.jpg
Mainline-#1---side---pre-phase-2.jpg
Mainline-#1---side---post-phase-2.jpg


They certainly got phase 2, alright..!

I'm actually growing telegraph poles y'know ..

Third one for the chop ..

Mainline-#3---side---pre-phase-2.jpg
Mainline-#3---side---post-phase-2.jpg
Mainline-#3-barrel-view-phase2.jpg


Last one, remember 'stumpy'? .. not quite ready yet, another few days or so ..

Not-ready-for-phase-2-yet.jpg


So this is where we're at in the vegging chamber now ..

Oh, and before I forget, the last of the trim from last year's Super Skunk greenhouse grow reared another 6 grammes of oil, making a total of 14 grammes off one plant. Half an ounce of oil .. dudes, that's not bad, eh?

Right, a chinese take-out and a movie or 3, methinks.
