Hydro in high temps
I am trying to get my hydro going here in hawaii.
The indoor room temps go from 77-84 and its about to be summer time so i expect it to get even hotter.
I have had limited success so far. Basically I get tons of root growth when everything is inline ph at 5.8 water temps 65C using frozen water bottles and DWC 5 gal buckets.
My problem is around the 5th day or so the ph will spike up overnight to 7. Once this happens i see nutrient defiencies in the leaves and growth stops.
I think this might be due to me missing putting a frozen water bottle in but im not completely sure since pytheium would drop ph.
I see tons of pics of ppl doing hydro outside in high temps...
How do they do this?
I feel like i am almost there if i can just eliminate these sudden abrubt spikes I think i would be set.
I have tried hygrozyme but end up with a tank full of foam real quick. And as soon as the foam comes the ph spikes.
The hydro store recomended dutch masters zone but i have yet to try.
Is there a easier way? i am tired of having to watch these plants all day switching water bottles up to 3 times per day?
With fresh nutes i am golden and the ph rarely moves. maybe .2 in a day or so.
