Hi Mr Groff,
Love your set up, I have an Amazon aeroponics set up that I have used with photos but my present auto grow I am doing in coco but I do like the look of these DWC set ups.
Im figuring you are in the UK ? I am too, down South and I have had unreal temperature problems on this grow, I have a well ventilated set up but because our house is so well insulated, double glazing, loft insulation, wall insulation etc the temperatures in our house are often 32C plus upstairs where my grow room is, even hotter in the loft so I just can not suck cool air from anywhere to drop the temperatures in my grow room.
My 1st few weeks were not very good with these autos, I assumed it was down to the high temps as I have read many times that 26C should be the maximum temp at which to grow an auto.
26C eh ? I have not once managed to get any lower than 27C, I have one of these thermometers that records the min and max temps so I know where it gets to at night and 27C is it.
I am usually at about 30 -32C so figured this grow would be a disaster.
Now I realise that my early problems were down to overdoing the nutes, I was feeding them as I would a photo strain (there is a lesson in doing a bit more homework 1st. D'oh !) and ended up with brown dying leaves all over, as soon as each set of leaves got large they yellowed, browned and died.
After realising my problem and flushing, flushing, flushing I now, at about 7 weeks have very healthy plants in full flower and packing on the buds beautifully.
But wait, I thought autos could not cope with high temps ?
I also thought cal/mag was a prerequisite of autos particularly when growing under LED as I am ?
Have I stumbled on something here ? Keep the temperatures higher to force transpiration and the deficiencies usually associated with cal/mag are negated ?
That would certainly seem to be the case with my present grow, it shall be interesting to see how, during Winter as the temps drop whether I start to have cal/mag issues.
Forgive me if it appears I am high jacking your thread, that is not the intention.
I am 'that mate' that flops into your sofa, tokes a few and then can waffle for England about our favourite plants.
I am always interested when a Golden Rule is broken with favourable results.
I shall be following this grow with interest as much as anything to see how your plants progress with the high temps but also because I am very interested in these DWC units and of course any thread using the amazing DP seeds is always worth following.
Good luck with your grow, I am sending positive energy your way.
edit; forgot to say I keep 25litre containers of water in my grow room to give it time to evaporate the nasties and that sits at 24-26C.
... lets see if I can tame it!
