Decided to go somewhere in between with circulation. I just found a decent quality 2500litre per hr pump knocking around from when I used to keep marine fish, so gonna use that on it's own for circulation. Think that should provide enough flow for 150litre reservoir. I will put a Y connector...

p.s I really only used the mlyar wrap to stop any moisture getting to the wood, as the lid is made of structural plywood. You really think the mylar could cause serious problems? My room temps are pretty low and stable. not much heat coming from my lights as I'm using LEDs

Thanks for the input buddy. I hadn't thought of protecting the water pumps from the roots! I really want to keep it to single reservoir with multiple plants, as that way all water is contained and no issue with potential leaks etc that would be present if I made a multi bucket recirc system and...

Also forgot to add, have pretty good temp control in the space I want to put this, I currently have 16 plants in veg in the space, pretty big around 5 weeks veg.....and temps are stable at around 23.5c with lights on....I checked the res temp the other day and I think was around 19c....It is the...

Yes I was planning on a full grow to harvest but with only a very short veg time , maybe 2 weeks or so with no topping. Do you think would be a problem if roots merge? The res is fairly big, 150 litres or so. I also could block up some holes and grow less plants... Any input on whether you...

Hi guys wonder if I could get a little bit of help, am pretty much a noob, did a few grows 20 odd years ago and since coming out of retirement have done a few reasonably successful grows in the last year. Have dabbled with a dutch bucket system and NFT (the former worked better for me). But I...

Thanks for the replies guys. great information! I thought still had a way to go, was just a bit thrown that quite a few appeared amber already. Also I didn't realise leaf trichs mature faster than those on the bud. I'll try to see if I can hold microscope steady and monitor buds instead.

Hi all, wonder if anyone could give the opinions on the stage trichomes are at on one of my plants. I cut off small sugar leaf and placed under digital microscope. It was quite difficult to get a picture with a lot of trichomes in view at one time. It was weird because on some sections of leaf...

thank you :-P

thanks very much. will try to get pic in white light. but from what the other guy and you say, my mind is kind of put at rest now.

thanks very much. i thought it could be, but i never noticed the balls where the hairs were coming out before this. female hairs seem to be coming more or less straight from branch on other strains. this one is the only sour diesel thanks again!

hi guys, wonder if you can help .I am complete newb ,well 1st grow for 20 years and back then only did a couple. am in about 6 weeks of flowering, pretty pleased how everything going but noticed today little balls forming on one plant (sour diesel strain) . i've been away for 1 week or so and...

quick update. i used the thermostat for a couple days and it worked fine, but wasn't too certain about the accuracy of the temperature sensor and also wanted to be able to monitor remotely. so ended up buying a device called sonoff th16 today nfor around £15(roughly $20) . very easy to set up...

i'm not sure it is "modified application". here in the UK this type of thermostat would typically be wired between a mains supply and an electronic/gas boiler. but they are also used to control electric storage heaters and other types of heating devices... not sure why having it connect to the...

thanks jypsy dog. i'm sure that is the correct thermostat best suited for a plug application. but i wired it as uncle reefer suggested and it seems to be working fine and the thermostat is controlling heater as it should. i think it should be fine as the thermostat is really designed to control...

thank you very much! apologies for needing it explained as if to a 5 year old....but really don't want to make any mistakes with electrics.not something i'm great with.

ok so if i have live/neutral/earth wires coming from plug cable(mains) and live/neutral/earth coming from heater cable ....do you know which wires from each go where in the thermostat terminal?

just noticed this diagram inside the cover. unfortunately i still can't work it out!

gotya! tbh the thermostat was only a very cheap one to start with. gonna try and join an electrician forum(lol) see what i can find out there. if no joy will just leave the heater running constantly. it's only pushing temp to about 80f when lights off . so probably not too big a problem
