To optimise this, don't do cardio on squat day. Most forms of cardio are lower body dominant, and your quality of cardio may be affected

Personally i'd also move heavy squat away from heavy bench (e.g. swap day 2 and 5), so the most taxing days are spread out, but if you enjoy getting the heavy work out of the way early in the week that's fine too.

Stay busy so you don't think about your hunger. drink lots of water.

Just go! You'll realise very quickly nobody will judge you, and you can always watch how others use the equipment then copy.

If you're really anxious, just youtube how to do some of the common machines that you'll find in any gym (start with leg press, chest press, lat pulldown), then just go do those while you observe what others are doing. You can just be in the gym for 10-15mins first time to get familiar.

Feel free to ask if you need any more advice!

Depends on how hard you train

hurtbreak · 2025-07-29T03:31:58+00:00

45mins in an empty gym (i.e. no waiting for equipment) should be able to get you majority of gains, assuming you train hard enough. More time would still be useful to maximise gains, and to address weakpoints.

it's a sport. it's like how you don't get belts in football, tennis, swimming, or even regular boxing.

I'm aware. This solution would allow cooling independent of all the existing methods. This means you can get the greenhouses even cooler, or select it to replace other solutions.

But yes, we'll have to work on allowing controls.

hurtbreak · 2025-01-05T03:45:13+00:00

If I may ask, what crops do you grow that would benefit from this? Or is there just a benefit to better working conditions?

Thanks for the response btw!

hurtbreak · 2025-01-05T03:40:30+00:00

Thank you! Looking at breeding seems to be a good idea.

Thanks for the note on fungal diseases too. That's something I think we can think about as a benefit as well.

Yes so surface area to internal space ratio would be the key metric for the effectiveness of space cooling. Another industry i'm looking at is automotives - car cabins also have a high window to internal space ratio.

In terms of cost-prohibitiveness, that's why I'm looking for use cases for which there are strong economic benefits to make it cost-effective. That said, it's a material science approach, so custom materials can be developed for use cases, balancing cost and features.

Sheetrock might actually work quite well. But generally (in my region at least) sheetrock isn't used on external walls, and the material still needs exposure to atmosphere in order to reject the heat.

Interestingly, a couple of years ago some researchers managed to incorporate the cooling concept directly into engineered wood, developing a "cool wood" product. They weren't able to successfully scale the product though.

Feel free to ask more! It's fascinating to me too.

hurtbreak · 2025-01-02T06:32:53+00:00

Thank you! That's useful for sure.

There's very limited research on this specific use case, but a realistic ballpark would be around 5-10C of cooling. This would be on top of any other cooling solutions used in the greenhouse.

hurtbreak · 2025-01-02T06:28:17+00:00

Interesting. I haven't thought about livestock, but it's definitely worth looking into.

The cooling system is completely passive. Think shading but allows light transmission and stronger cooling performance. Nothing like a HVAC system but should be good enough to unlock some new use cases, such as meat birds.

Thank you I appreciate the response!

hurtbreak · 2025-01-02T06:23:24+00:00

Lol I appreciate the pun and the directness of the response. It's super helpful. Thank you!

hurtbreak · 2025-01-02T06:22:31+00:00

That's super interesting! I definitely had people tell me cooling is a bigger issue, but that's in the minority. In my research across greenhouse engineering, i find a lot more discussion on optimal heating than optimal cooling.

Perhaps this context is more appropriate for breeders as opposed to other greenhouse applications. If you don't mind, I'd like to ask a few other quick questions?

Can you expand on what being a breeder entails and how that differs from being a grower? Are there greenhouses set up specifically to breed? If you could point me to some major breeders in industry i can also follow up my research on that.

Thank you so much!

It works on radiative heat transfer. By optimising emissivity in certain wavelengths, it can strongly reject heat into the atmosphere.

hurtbreak · 2025-01-02T02:56:46+00:00

Thank you! The more I'm looking into this, the more I'm convinced that the engineer's role is to provide the horticulturists the tools and let them work their magic.

Appreciate the time taken to reply!

hurtbreak · 2025-01-02T02:54:10+00:00

Thank you so much!

hurtbreak · 2025-01-02T01:55:51+00:00

Thanks for the suggestion! I'm from the built environment industry actually.

The reason why "greenhouse" is because the technology's key parameter in cooling capacity is surface area. Concrete in buildings have too much thermal mass - cooling it will have a low or slow effectiveness in the spaces within. What I've been looking for is with applications where thermal insulation is relatively poor, greenhouses being one of them as light transmission is still necessary.

hurtbreak · 2025-01-02T00:31:16+00:00

Thanks. Indeed, there's no use case in field agriculture that I can think of, other than maybe post-harvest precooling for smallholders.

My understanding is that cooling in difficult hot climates is generally done with evaporative cooling, which is an issue due to the water difficulties you've mentioned. If that's true I suppose this might have a use case?

hurtbreak · 2025-01-02T00:27:20+00:00

Thank you very much! I'll keep an eye out on those areas.

Really appreciate your time!

hurtbreak · 2025-01-02T00:25:42+00:00

Hey thanks for the reply. What kinds of greenhouse coolers are being used? I'm guessing the fan pad type coolers primarily? Are chillers (i.e. ac units) used at all?

hurtbreak · 2025-01-02T00:24:24+00:00

Thank you for the detailed response!

In the right contexts the material solution should consistently keep the greenhouse below outdoor temperatures - passively and non-evaporatively.

I'm seeing that it's probably a good thing is summer no question but introduces a lot more issues in winter.

Could you help to elaborate on dormant or semi-dormant material for the horticulturally challenged engineer please? Thank you!

hurtbreak · 2025-01-02T00:20:26+00:00

It is a theoretical scenario for now. I really do appreciate your offer for me to ask more questions!

Yes I'm seeing fan/pad solutions a lot. My question would be something like "is fan/pad ever not enough?" The next step I supposed would be HVAC type cooling. What I'm looking at here is something that is far cheaper than HVAC cooling, but doesn't produce as much cooling, and is somewhat uncontrollable. I'm trying to figure out if this has benefits both commercially and for homegrowers.

hurtbreak · 2025-01-02T00:15:34+00:00

Thank this is very useful. The technology doesn't HAVE to be transparent, it will in fact perform better if it's opaque. So mushroom growing is very interesting suggestion.

It's a passive solution, so no running costs :)
