Cucumbers Grown in the AeroGarden - Episode III (A Change of Nutes)...

 

After two previous grows (successful to a small degree), using the General Hydroponics Flora Series (micro, grow & bloom) I will now change tact and use different nutrients...

What I'll use now is FloraMato which seems more suited to growing cukes. The FloraMato I will use is in liquid form and has to be mixed with FloraMicro (normal & not hard water variety) - I cannot get the one-shot dry formula.

 

 I've worked out the dosage for the AeroGarden and it follows below :-

EC            Plant Phase                       Approx. Weeks            FloraMicro         FloraMato

0.85          Seedling                                        1                               3.2mL                 3.2mL   

1.6           Small to Medium Growth            2 to 5                          6.4mL                 9.6mL

2.1           Medium to Maturity               6  Onwards                       9.6mL                 12.8mL 

 

As per my other grows, my Classic AG is modified. I have taken the whole water pump and stand out, I have an airstone supplied with an air pump producing bubbles and aeration. I am using rockwool for my substrate and this has been placed in an AG6 pod which is longer, the original smaller Classic pods have been dispensed with. I will not be using the standard light hood, in it's place is a 125watt CFL grow lamp in the blue (6400K) spectrum.

The lighting cycle will be 16 hours on and 8 hours off.

That's probably the right

That's probably the right thing to do, the AG is quite small and I assume it cannot support this large plant. Limiting the cukes as you said could do the trick - not sure if I'll do this again in the AG though, it's a tough grow beset with many problems.

Peat, If you try again, is it

Peat,

If you try again, is it worth limiting the cukes to 3 or 4?  Could it be that cukes are taking all the nutrients, leaving none for the leaves?

Many thanks to you

Many thanks to you both. 

Seems all I have to do now is remember what I've done.

Enjoy!

It's here, scroll down to post number 26 for all the details.

Edit: gisette edited to make the link go directly to post 26. FYI, the "#26" type colored label at upper-right of a post, is a link directly to that post.

Peat Edit - Thanks, will remember that.

Ooops, this grow was with my 125 watt CFL

Hi Peat!

Could you please post a link to that CFL light? 

Thanks loads!

Enjoy!

Thank you. Perhaps I did

Thank you.

Perhaps I did prematurely misjudge the plant, those cukes were full of flavour and it did grow well - I've pretty much had enough practice by now after all.

Time to move on again though, the next cuke can wait a little while longer as I want to try my raft system with this light. I'll take a back seat and watch yours and Beth's develop, hopefully with better results.

I think five ripening at once

I think five ripening at once was a stunning achievement for such a cramped plant! Resounding success! Think of the fastest growing AG plant we know - lettuce- and imagine a week's great yield liquified to the density of a cucumber. Probably one cucumber.

But definitely, 3.2 liters is nothing. Cucurbits drink like crazy, and transpire lots. And if they can't transpire enough - too few leaves - the vine fails. I think it's the leaf-sweat that draws water up the vine.

I loved this grow, Peat! Just added pH Down to my dishtub cuke to get farther down toward your 5.5 pH. (Didn't want to jump to that conclusion in case sweating a couple days brought it down thataway anyhow. But my plant doesn't seem big enough yet to alter the pH of ~7 liters.)

I did not know that, I guess

I did not know that, I guess I expected lots of cukes dangling down. So, five after all was probably some achievement for the little AG then - perhaps not so bad after all?

That said, a bigger reservoir will stabilize the wandering pH and create less stress on the poor plant - my pH was down at 3.8 some days, root destroying zone!!!!

I guess I've never seen a

I guess I've never seen a cucumber plant with more than 5 cukes growing at the same time, Peat. They're not like tomatoes - each cuke develops very fast, so 5 in parallel is a substantial production rate. A tomato bearing only 5 fruit at a time, with 6 weeks to ripen each, would be poor - less than one tomato a week. (Though, averaged over the whole midsize tomato plant lifespan, I think my outdoor ones do produce less than one tomato a week, with substantially more light input.) A cuke might carry more in parallel, under excellent conditions. But I don't think it's normal, or a valid yardstick for success.

Yeah, a bigger reservoir is worth a shot.

Ooops, this grow was with my 125 watt CFL and not the LED - that's here.

Thanks for the compliments, I think this one will head for the aero unit next - I need to get another timer though, one that can cycle in 15 minute increments to let the 'air' roots develop more.
