I could go into theories but I rely on what my eyes tell me with results and experience.

However if you want a theory the air gaps around the lid by the handles (4 of em) have more surface area than the holes in a traditional monotub. But my holes don't have any poly in them.

also I think you still believe CO2 sinks

Here's some of my results

Thanks for the tek, works good!

First flush in the 32qt mono. 761g wet



This is the first time I’ve used the tubs specified in bods Unmodified mono tek. I didn’t have to mist much with this tub, it basically took care of itself 👍

My third go with unmodified tubs. Turned out real nice.

Better results than some who have been growing for ages

i have never ran an un modded tub but i have seen not so good flushes from them in the mc

Unmodified too.

i heard some one say for years fanning is not fae

you should listen to that person. fanning aint doing shit. who fans anymore?

dude really aint on the same lvl of growing as me to compare note mo

Everybody pull your dicks out...were measuring again.

Unmodded tub is better than SGFC. But for some reason back in ancient history you did SGFC and think that it will always be the best. A mushroom could grow a mouth and tell you directly that it prefers the HC and you would still be like "naw yal wrong".

Mateah said:

You were joking about fanning right? Right?

Mateah said:

Are you convinced yet that it's possible to grow flushes from wall to wall using unmodified tubs?

---

imma try it i understand why u guys think it better than a reg fc buy ya there still supar to a reg one
all u guys have to do is pop 2 inch hole in them and i bet your yeild will raise but well see

So I’ve read the tek on the HC with fruiting cakes and will be trying it shortly.  But how are you using the HC to fruit bulk subs? 

For the cakes they float on a plasma of verm and have foil underneath.  How the hell do you float a bulked substrate through the length of the HC?

Am I missing something here?

tripdawg420 said:

i would stay clear of that

I'll put 27 of these into different types of HC setups next week. Some will fruit with the lid flipped and some with the lid regularly on.
o what happens if I get full flushes from most cakes with minimal 'manual' fruiting?
Will that open you up to some new ideas or is it still shit compared to other setups?

SumFunGi said:

Have you posted your recipe for the bulk sub in an HC?  If so can you link it or point me in the right direction?

I’m a noobian brotha and need directions.  I’m doing the cakes in an HC, but wanted to try bulk as well if I knew what to do.

Thanks for the helpful tips!

Third link in my sig if you want to try Spawning cakes 
For bulk grows just mix your spawn and coir inside a tub and that's it spawn can be grain or BRF or whatever.

A bulk substrate creates its own micro climate it doesn't need a fruiting chamber it IS the fruiting chamber itself

Co2 will settle our of air with no movement. In a sealed airtight box. If there are currents if air then there is mixture. The air does circulate as describe in the mono Tek but not because of co2 settling.

What if you have many tubs? Isn't it better to have a set and forget system?

A column of air has to be about 5 miles high for co2 to settle out with no convection. Otherwise Brownian motion keeps them mixed

This is known as scale height for gas pressure

I'm pretty stoked to not have to cut holes in tubs. Last time I did a mono was like 7 years ago.
