Growing indoors in the summer can be awful.  Excess heat can cause the plants to wilt or droop.

Some ways to reduce this :

- lots of big circulation fans.  But bear in mind too much wind blowing will in fact stress the plants.  So aim fans towards walls cools the air but lets it diffuse in wind speed.

- extraction.  Something I find quite ineffective unless you use huge 250MM or several 150MM fans.  Obviously for smell extraction is essential, it’s #1 use.  To much extraction makes the air dry and humidity drop so I do not advise this except for smell removal.

- reduction in lights.  I think this is something worth noting.  Maybe switching off 1 out of 3 lights will increase growth – the reduction in temperature will make the plants perform better and switching off 1 of the lights might not be so deterimental.  Check for stretching of plants if light is inadequate.

- low powered bulbs.  Well, they’re crap.  They don’t work much.  This isn’t a solution.

- put the light cycle on at night.  Probably the best thing you can do.  Make sure no light can escape however.
