Re: Frank's easy mini-GH, no condensation and 24/7 FAE [Re: FrankHorrigan]
    #18382323 - 06/07/13 09:45 AM (10 years, 9 months ago)

Frank, I noticed you're advocating for wire shelves. How much of an issue has rust been?

I have a plastic height-adjustable 5-shelf unit (18"x32") wrapped in 6mil plastic and I'm working on dialing it in empty. I know this will change a bit when full, but will give me a good baseline.

My vicks cool-mist (impeller type) is keeping it at 93-95% (measured in the center of the middle shelf) pulling in fresh air at the bottom corner like yours is. A lot of that moisture is condensing on the underside of the first shelf above the humidifier and raining back down. This led me to think the plastic shelves dont have enough negative space in them....although they appear to be about 50% holes, 50% solid.

I also tried plumbing in a very good ultrasonic I have from the outside, into the center shelf but it too seems to just fall to the floor after completely fogging out the center :thumbup:.  Keeping the top two shelves adequately humidified seems to be my issue.

Any advice based on the above? Perhaps I should re-purpose the plastic shelves and switch to wire. I cant find martha's or mini GH's at stores near me so I'll be making mine from shelves and a plastic sheet. This at least gives me the ability to use any shelves. I'd like to keep the dimensions within 19" x 42" x 8'

As always, I appreciate your input and knowledge. I recently switched back to using a TiT incubator like everyone used to back in the day after reading your write up and I cant believe I ever stopped. The difference is significant, even over a temp-controlled room :thumbup:

:thanx:

I recommend (and bear with me here) ditching the impeller.

IME impellers make things very wet and its difficult to not soak everything.  I swapped my impeller with a cool mist and ultrasonic (neither piped in) and never looked back.

The buffered RH FAE allows great evaporation in between ultrasonic "mistings" so the casings /subs never dry out before the first flush is over and it needs to be re-cased anyhow.

Rust has not been an issue with my wire shelves, I've done about 6 months of runs on these new shelves and all is well. I even double checked today.

I hope this helps!

I knew the line about ditching the impeller style humidifier was coming :smile: Since it's what I have I will turn it down to low to try and mimic the rate of a cool mist wick-type. I toyed with the low setting over the weekend and it seems to not be soaking everything anymore. I'm stopping by a cigar shop today to pick up a new hygrometer to double check the humidity. My digi says 94% and my analog one - calibrated with the wet paper towel - reads 95-97% hard to tell exactly and that's just with the cool-mist running on low. Since it's on low I have a little fan pushing air up from beside the cool-mist to helop circulate stale-air.

I'm glad to hear you haven't encountered rust issues. I had read some posts, one by RR, where they had terribly rusted shelves within a week. That's why I went plastic and chose the shelves with the most amount of ventilation holes in them. However, the wire shelves offer at least triple the hole-space as compared to plastic. I'd like to try 360 degree fruiting from some cakes from small trays which would require wire shelves. All my mono's seem to want to fruit 360o anyways.

I was going to build a PVC frame to hold the plastic sheeting around the shelves...then I came acrioss corrugated plastic sheets:


Can you think of any reason for me to NOT make the sides, back, and top of my greenhouse out of a clear version of this material instead of plastic sheets on a frame? I think it would be easier to work with and doesnt require a frame to hold it up. Only the front "door" with zipper would be 6mil plastic sheeting.

Sorry for all the questions, if you think I should just start a thread instead just say the word. I just thought maybe this discussion might help others referring to your tek's (like I do all the time) that cant find mini greenhouses in stores anywhere, like me.

FAE: As much as possible. For low-RH tolerant species: With the filter/wick-type cool mist buffering the RH, you can and should run your cool mist 24/7.  This provides a ton of FAE. You can adjust the amount of FAE by how zipped/unzipped the curtain is on the sides. For cubes: I have been finding my casing layers dry up too quickly. To compensate, the cool mist is on 30 min then off for 30. The ultrasonic runs 15 min on every hour, right after the cool mist shuts off :thumbup:

Small update.

That's a bag of WBS spawn intended for a tub that had a pea-sized spot of bluing myc on it. So I cased it with 50/50+ and fruited it in the greenhouse. Looks like a leucistic in the middle there :cool:

You mention using two greenhouse shelves back to back.  Do you cut the backs out of each greenhouse plastic and seal them together or something?

I'm thinking of a mini greenhouse setup, would adding a cool mist and an ultrasonic on a cycle timer take up too much room if only one GH is used?

No, no, it's not GH shelves, they are actual 4-tier wire shelves.

The tarp is from a large (double-wide) mini-GH found at a garden store.

You can do this with one set of shelves or two.  Use the same equipment for either.

Some people "pipe-in" their humidifiers to save space and evenly distribute moisture and air. I think it's over complicating things.

Yeah, I'd rather keep the cool mist and ultrasonic inside the greenhouse.  I'll probably just order the standard 4 shelf greenhouse and see how that works out.

I agree.  RR has always maintained the same opinion, I believe.  And for the record, impeller humidifiers ARE cool mist humidifiers.....

I realize that. That's why I made it clear in the OP what type of cool mist humidifier I use:

FrankHorrigan said:
I use an ultrasonic humidifier and a filter/wick-type cool mist humidifier.

It's a $35 cool mist (wicking/filter) bought from a department store during winter months.  It holds 1 gallon of water and it has a low and high setting. I use the low setting.

Frank,

I see your trays are aluminum containers lined with garbage bags. Now do you cover those before fruiting after you add the spawn and substrate mixture together to let them consolidate?

I thought you were distinguishing between impeller humidifiers and coolmist humidifiers.  Nice grow, BTW....

Yes, I cover the trays with foil or press-n-seal, whichever is laying around. I poke 5-6 small holes in the cover for GE.

Then they are cased and fruited immediately once 100% colonized.

:thanx:

Gotcha, no, just for simplicity sake I was referring to impeller CMs as impellers and wicking/filter CMs as cool mist. I hate having to distinguish between the two every time the phrase comes up.

Frank:

Have u ever fruited 'uncased' in your GH?  I'm doing 6 trays uncased.

They are p envy -I see some pinning. --seems slow though

My issue is that they turned blue after 2 days in the GH.  I've got them all back normal, but one is still very blue in the center and has some weird looking knots on it and kinda oozy.

I'm not sure its even knots. Oh, and one tray went into the trash.  There was green mold on the side. The rest look fine

I'm thinking about Late Casing.

I have to run the ultra sonic 15 min on and 25 min off with the coolmist 30 on/30 off just to keep the RH at 90% and it seems like

What do u think about Late Casing or would u just see how it goes

^^I've done un-cased in a GH; didn't care for it.  That bluing is usually from heavy water droplets bruising the substrate.  Also could be from contamination....

It is contaim.

Just threw out 2 more trays.

I guess the cool mist blows the trich everywhere....

Still have 3 good trays and I cleaned out the entire GH then put the good trays back. 

Ill try late casing the good ones tomorrow. maybe they will make it.

I wonder if I had cased, if this would have happened..

I mean, it blows the spores everywhere, but if you have properly pasteurized substrate and clean grain spawn it will not be a problem.

Casing shouldn't matter if the casing layer and sub are properly pasteurized and the spawn is clean.

Sorry for your loss :frown:

This is true.  I have recently learned that the fruiting environ does not have to be that clean, though I have always tried to keep it as such.  I suppose I got a little "caught-up" in the Lysol/Iso craze hahaha.....

I reiterate, that sucks about your loss....
