I've been growing out a GD female for the last while now and have managed to get her to 47 days flowering.
Grow room consists of a 600W Son-T in a Cool Tube with a 6" RVK for extraction which is pulling through a 6" carbon filter. Air in is via another 6" RVK and both are wired to a thermostatic fan speed controller.
Plant was vegged for 4 weeks under a twin 55W floro unit for 24/24 and topped a few times to keep the height down / cuttings. She was then placed under the HPS for 2 weeks of 18/6 hours of light, then the light was changed to 12/12. She was 28" tall at the start of flowering; excluding the pot.
Grow medium is straight allmix in a 10 litre pot. Feed is Biobizz grow and bloom along with some topmax. She's been getting 3ml per litre grow and 2 ml per litre bloom per water. I've been adding 2ml / litre top max in between feeds.
No real problems with the plant other than the lack of colour which the plant has taken on over the last month. Not sure if it has been down to cooler temps or simply because i'm not feeding it enough.
So here she is at day one, 28 inchs tall ... [attachmentid=33280]
