    I'm expecting all the above to change when she starts getting bigger I'm taking notes though for future reference and to see if there is any kind of a pattern.

    When using an air stone ph will naturally rise.

    Aeration increases Ph because it reduces the amount of Carbon Dioxide within the water. If you add CO2 it causes the Ph to drop. If you add O2, then it removes CO2 which causes the Ph to increase.

    Usually when I Google something about plants it brings me right back here to the talk. This post covers how the pH can change due to too much air.

    Back when I was doing bubblers, I did an experiment with air supply and pH. One plant got 4 times as much air as the others. tbf, all of them got loads of air, huge airpump. Anyway, the one that had 4 times more than the others had the pH vary by only 0.1 compared to the others.

    Might be different with lower levels of air.

    Well I've got problems..
    Lots of condensation and heat stress or light stress?

    Condensation is around the door area so I'm guessing as the whole room is insulated using 50mm kingspan and the door has got bubble wrap and emergency blankets stapled on its not enough.

    I've pulled up the light incase it is lights stress but as far as heat goes I'm snookered as its a sealed grow so I've got no cooling in there. Attachment 400139Attachment 400140Click image for larger version.
