Green Crack Auto by FastBuds

On going wintery weather is regularly forcing outdoor temps below freezing and the grow is in a room without heating. With this in mind I invested in a water heater to keep my nutrient solution from getting too cold. Seems to be doing the trick but as my small water bucket is sat on the concrete floor. I need a trip to the local DIY store for some polystyrene insulation board for it to sit on. Light intensity is now at full power and still at 60cm above canopy. Increased nutes to 0.75ml/l. Pots take 400ml of solution which for now is lasting 3 days before before the babies need another drink. All looking good so far.
