One week later they seem to be growing a lot faster. Ive started feeding them seaweed extract fert and i add a tiny bit of a C02 tab into the water. when i was in the shop getting the mylar i asked the guy in the shop how much was a pack of C02 tabs and he just said "theyre pretty expensive but take a few if u want" so i got a load of free tabs and he knocked of â?¬5 off the price of the myalr:thumbsup:. I also bought myself an oscillating fan and a pc fan which i hooked up to an old SNES adaptor. All i need now is a space heater. The LR2 seedlings are doing pretty good also, showing no stress from the cold so far and the temps are getting pretty close to freezing. I can only have the HPS on 12 hrs a day cos the power bill came and it was pretty high so i have a daylight bulb (40W i think) on 24 hrs which hpoefully will keep them from flowering even it doesnt enduce any growth.
