I also work from a home studio, we have a 4 bed house and only use 2 of the rooms, my wife says we live in a sweat shop ...
The problem I have is that all the printers, I have a large format printer, a laser printer (always on), 2 inkjets (not always on) and my T-jet in the same room, along with my heat press ...
Im in the process of finishing a project where by i have bought an arc shaped shower cubical and im using it in the corner of the room to box off the heat press completely from the rest of the room, I have also bought a kitchen hood extractor. the plan is below the table the heat press in on is to knock a vent to allow cool fresh air in and have the hood above the press extract the gasses etc out ... although it also has a carbon filter for recirculate but im not sure if thats a good idea as in will the carbon scrub out any fumes... or am i better going for plan A and running a pipe up into the loft and out the edge of the roof ? ... I have had issues with my chest due to pressing in a room, i currently have installed a bathroom extractor above the press in the ceiling and if im doing mugs I tend to crack a window and wear a mask.
I use a wagner with a popup faketan tent in one of the bathrooms below an extractor.
Unfortunately the print room has a window but my plan with that is to get some reflective window tint as used on cars. Also the lighting in there is halogen type spots, so i will replace these for LED's.
The humidifier I use is a 5 litre one, and on full power on a warm day empties in about 5/6 hrs, the problem is keeping the temp down in the room, im thinking of placing a fan behind the humidifier as i use this trick in the bedroom, which does cool the air... I did consider looking at an aircon unit, but that takes the humidity out of the room ?
The one potential problem with an indoor greenhouse wouldnt it be quite warm within it ?
As with most small business's I would love to move into purpose built premises, but the cost would remove too much of the much needed profit.
Where I live in the northwest of England over the past year, due to the recession, now have around 10 new competitors, people who i assume have lost their jobs and used their payout money to set up as "printers". luckily so far most of them have bought vinyl cutters and use heat transfer images with the odd ones also buying embroidery machines, and not DTG as of yet. The problem is all or most of them have always (again I assume) worked for other people, and dont understand the concept of profit and ROI, opting to compete on price over quality, which will lead not only to putting themselves out of business but also people like myself. One competitor who may as well just given things away, is having an issue due to not insuring their business, penny pinching on one side whilst undercutting on the other ... they have had a fire and lost one of their embroidery machines which i think is leased so needs paying for around £20k ...
Any way off topic, but back on topic I may look at moving the whole operating into our converted garage, that doesnt have windows, but is currently a 6 seater cinema / my design and chill out room ... not sure if i can lose that lol
