Hey thizz that looks good ... how do you like the nutradip gear mine is on the way !!
From what I have learned in theory/practice, is that your PH is dialed in 100 % for your application aka deep water culture , my phenotypes grow very fast in veg in that range.
The difficulty lies in keeping it there as the nuts are consumed (without adding 2 much of stabilizers)... so constant PH is paramount.
In my case, as per the strain I grow (phenotype) the ladies hate the heat ...85 would screw them up ... I have learned the hard way.
(Please forgive me if I am telling you stuff you might already know ... I don't know your experience)
So if you can dial it constant at +/- 1 (80) that might help .... but that pertains to my strain .... and thermal dynamics in the grow room.
I also had to purchase a portable air conditioning unit to achieve this. So in a small stealth you might have no options.
Also, there is two types of heat .... ambient and
radiant heat.
To have ambient at constant, through the light cycle is one thing but ... one must also take into consideration the radiation generated from the lamp used. I am taking about the distance the lamp is suspended over MJ. And this will depend on the wattage u are using at the time.
So in essence, you can have ambient temp at lets say 80 constant .... with fans going (this is good to keep the air from stagnating and for the movement of co2).... but in reality, if you set up your light to close ... the tops will get way more heat .... past the 85 mark .... effecting the growth.
Please forgive me if this
tit bit is redundant as you might know this already.
I pulled up a chair and will be watching.
One more thing ... what strain are u working on here .... I would like to be able to taste it as I glance at your pics.
Cheers
