Accidentally was uploading into week 4 so had to reupload for week 5! im shocked its been 5 weeks already time really does fly by!
Got myself a new tent as my 0.8 x 0.8 space was just to small with the dehumidifier in there now...i got myself a 1.2 x 0.8m tent and its absolutely spot on...much neater and the extra space has allowed me to use an oscillating fan for air circulation...
The inbuilt controller on the dehumidifier wasnt very accurate so I invested in another controller which has 2 outputs so I can run my 80W heater and dehumidifier off of that and its working perfectly...ive got the humidity set to 50% with a +10% setting so it runs for a decent amount of time and isnt turning on/off constantly...
Carbon filter is fitted...as i dont run an exhaust im hoping to just scrub the air within the tent...has anyone ever had any issues with this kinda setup rather than negatively pressurising the tent?

@Ga4rd2en0er, ah thats spot on then, some dehumidifiers have a connection so you can run an additional pipe that can go straight to a drain or an even bigger resevoir/bucket...i use all my dehumidifier water to water my plants again which may be wrong but it has prevented salt buildups and its at a good PH as well...
definitely I had a 0.8x0.8m tent at first and 5 autos in there plus the dehumidifier wasnt pleasant to work in...thats why i upgraded to have a slightly larger tent just to fit it all in...its very compact and amazon.co.uk (if your in the UK) has one for £90 brand new at the moment :)

@CronxWarrior, great info. I usually spend about 2 hours a day at each grow I have going on so I don't mind a little extra work with emptying out. I've been looking on the second hand market and the size of your unit looks about the right size for my space. My 4 autos are taking up 90% of the floor space in the 1.2 x 1.2 x 2 meter tent I have. I'm coastal and humidity will avg 55 to 75% year round.

@Ga4rd2en0er, Hi matey, i bought a refrigerant based dehumidifier as the temperatures of the grow tent should be around 25-30°C depending...I keep my tent at around 28-29°C because I supplement with CO2 and was told you need higher temps to make it worth it...
If you keep your tent at a lower temperature then a desiccant dehumidifier is best but they are aimed at much lower temperatures at around 15°C...
I managed to find this Delonghi DEM10 for £50 second hand local to me...im not sure where you are based but if you can find any second hand refrigerant based dehumidifier local i would go with it...especially if its a good brand such as delonghi etc...also get one with a resevoir thats as big as possible, my dehumidifier only holds around 2.0L which has to be emptied every 2 days sometimes which can be a bit tedious!
