    Default Algaecides

    I have a real problem with water collecting between the plastic panes of my GH and consequently growth of algae. What algaecides would you reccommend to rid my GH of this unsightly problem? I want it gone! While I appreciate resolving the condensation problem would stop the algae, this issue can't be changed since the twin wall construction aren't sealed units.

    Bleach water and a mop will help remove it. Good luck.

    The problem, Bruce, is that I can't physically get in between the panes to "wash" them. I can spray liquid.

    Oh! Sorry, I misread your request. I thought it was on the surface of the panels facing the inside of your greenhouse. Question for you: If you spray an algaecide into the panels, will the liquid wash all the way through and come out? If not, the dead algae (brown muck) will be left inside to muddy the panels too.

    We use a product called 'Baquacil' in our kool-cell tank. It keeps the pads from growing algae. It does kill the stuff and is chlorine free, but we do have to dip out the dead stuff from the tank occasionally. Baquacil might be a better choice to spray since it could get into your eyes. As with anything you spray, be sure to wear some protection to avoid breathing the vapor.

    Cheers,

    You could try one of those portable steam washers that are used for cleaning grout from showers and tubs. Get a nozzle that is small enough to fit into the seams and let the steam kill the algae. Just dont let it get too hot or you risk melting or warping the poly panels.

    If you dont like to use steam, you can get a pump sprayer and rig it up to a flexible straw nozzle (similar to the straw nozzles that come with the WD-40 cannisters). You fill the pump sprayer with your favorite algae killer (Physan-20, Bleach solution, etc) and insert the flexible straw nozzle in between the panels and spray away.

    Also, cant you use the greenhouse sealant tape to plug up some of the gaps on the edges of the poly panels?
