General Cultivation Q&A

Looking back at last 2wks when I went from led for seedlings and small plants to 600w hps here is what went wrong . 1.... plants dried out looked similar to nutrients burn 2.... humidity below 40% temps 28 to 31deg 3....unstable environment 4....amount of air exchange After many countless hrs of watching and recording info , buying humidifier,searching web for hrs looking for something similiar, No matter what I tried no improvement, clutching at straws I decided to switch exhaust fan off for a couple of days using the vents in the tent as ventilation so opened 1 vent at bottom 2 at the top and recorded info over next 2 days, well what do you know temp range 24to 30 de…

hi all. i have a seedling that has 3 cotyledons. 1 normal one and 2 that seem to be sort of fused together on the bottom half, but separated top half. i guess this shouldn't have much of an impact on the rest of the plants life?

Howdy Folks, Still trying to figure out a better way to keep my Res cool over the summer months and came across these little gadgets, I think they are about 40mm - 60 mm wide so quite small but i was thinking that 3 or 4 of these with computer heat sinks pasted on the backs will drop the water temp in a res by enough to do the job, They run off 12 volts and they seem very simple to set up. I will copy a couple of links that i have been looking at. Let me know what you think.

Was trying to work out why my plants aren't well checked everything water ph soil ph drainage ventilation temperature lights were good even went to extent of checking light meter values still no success, after checking grow diary I noticed my humidity never got above 40% my plants looked dry and showed what I thought was but burn or light burn under the led red light you could really see the difference in colours of leaves, I thought maybe a wet towel in bucket of water would help , still no good so I went and brought a humidifier and bingo humidity 60% maxing at 80% the growth and improvement has been significantly increased . So I guess the moral of the story is in a sm…

Hey everyone, last grow I only got entill 8 weeks and started getting mold, I decided to pull up before I lost out even More... Since then Iv brought a Ionmax ION 610 Desiccant Dehumidifier 6L and the humidity has been around %45 %50 now the room temp is always around 20 to 25 now. Will this be enough to stop mold this grow? I still notice moisture on the leaves of a morning so a little worried there... How can I prevent mold? What's the safest solution to have on hand to spray the plants just in case of mold? Also is my humidity at acceptable levels during flowering ? The unit is set at %40 but seems to only get the room down to %45 max

We all like growing cannabis but there is another useful kind of canna that is handy to grow in the garden and there called canna lilies, canna lilies are not technically lilies at all but they can however be grown as water plants in fish ponds and around small dams,canna lilies grow in full sun but will tolerate filtered sun and shady areas as well,both the leaves and the flowers come in variety of colours from green,green blue,purple,red,deep purple leaves and flowers that's come in pink,red,orange,yellow and they give a real tropical feel to any garden,they grow from a rhizome just beneath the soil and are similar to the ginger family and multiply pretty fast ,canna l…

I have been a smoker for probably 39 yrs have read a lot about med mm and thc & cbd counts what I can't seem to get my head around is how different strains can be used to treat different ailments,unlike pres drugs which are specifically made to target pain is specific ways what is that makes different strains target specific pain , don't get me wrong I know things like epilepsy cbd is a proven treatment as it is with cancer patients helping appetite but what scientific evidence to back up is there that a particular strain will target things like anxiety back pain etc ?

I have a LU400/600w photosynthesis light would I get any advantage by using 108w COB led grow light at the same time,also are there any advantages in running lights 24/7 as to 20/4 or 18/6 thanks in advance

Hi all Question regarding finger numbers on leaves. Any truth to the idea that 3 or less fingers is less then desirable (unless its mongy weed) and can impact on potency? Ive got one thats more then 5 weeks after reveg and shes throwing 3,2 and single fingers. Will this trait be passed onto any clones or can i expect them to have the full 5/7 etc fingers once established?

Just starting my second grow with autos. It can be seen in the journal section of this site. I've been researching what the best light cycle is for autos. The general consensus is either 18/6, 20/4 or 24/0. Just wondering if anyone has any personal experience and has seen the difference it makes with these different light cycles? My first grow I did 20/4 the entire grow which worked well but I'm wondering if 24/0 may work even better. Thanks for any responses
