Auto Pounder with Cheese

Cold night time temps have really set in this week. It's been as cold as 5c (41F) in my garden shed where I'm growing but have managed to keep tent temperatures, lights om between 19 - 25 (66 -77 F) lights off during the day between 19 & 20c. Things really got bushy this week as I contunued LST which was started at the end of week 3. So much new growth which I'm sure will end up turning into tasty buds. Considering the conditions I'm really happy with this grow. No fertilizer has been used and I'm planning keep feet free with the entire grow as I've gone with water only living organics soil which I'm hoping will bring the results I'm after and is hassle free. https://easyasorganics.com.au/product/water-only-organic-soil-blend/ Both Tube heaters have been hard at work keeping the grow environment happy...I wish I could get just a little more heat but when it's this cold it's impossible. Moving the tent to any other location is also impossible. Please comment on what u think as this is the first indoor grow In done. Also, apologies for the purple haze in the pics. I'm taking these late at night while the lights are on. I don't want to switch off lights, wait for them to cool b4 switching back on for a few pics. The plant I can say for sure is a healthy green.
