General Cultivation Q&A

just finished doing a setup with 2 600HPS cool lights.I have my ducting running out through vent i made but have not set up ducting for air intake as i was wandering if i left ducting off would this also take the air out of the room or would this warmer air stop my lights running as cool as they should.On the site where i order my equipment from they had an end cap with a flap going only one way so air could be drawn in but none come out but i cant see why you would use this as the air is only going to go one way while the fan is on any way.Can some one please explain these things to me.

Anybody given this a try yet?Was thinking about giving it a try on my next grow althouth I am happy thus far with what I have been using just interested to try something new and no part A and B to mix.

I have a few questions on Auto's..I'm running 20 hours on 4 off for lighting is that the best lighting cycle from start to finish? Are Auto's heavy or light feeders? Would I be best to run fluro during veg and then swap to HPS or just run HPS the whole grow? Any help would be greatly appreciated cheers Buzz. P.S. tried to send shroomyshroom a this message and failed

hey just wondering if you can pinch a plant and supercrop the same plant? also how long before you can flower it after this is done???? grown indoors as well

I've been growing a number of plant with my mate , we've both been making the feed up but I've only just found out that when he's been making the which has been about 80% of the time all throughthe flowering stage he has been making the nute mix with hammerhead pm 9 /18 and still adding the veg nutes instead of the flowering we've started adding bud lead 2 weeks ago ,when I've been making the mix up I've been doing it with the right nutrients, As I only found out about two days ago I would like to know how this will affect the final product apart from the shitty yield will it affect the flowering times as some of the plants should have finished a couple of days ago yet t…

Hey have been wondering when is the best time to start adding nutes to seedlings? My current grow (1st in about 6 years im a little rusty) I got going from seeds they are about 5-6 weeks old now and going good. I started the germinated seeds in rockwool cubes and gave em naught but water for the first week then started adding about 15% solution gradually increasing to 50% when i trasplanted ( coco + perlite) after about 3 weeks and up to 100% now. Is this enough? Or should i be a little heavier handed?

i am looking to buy seeds within 3 months was on attitude website and they had auto flowering seeds, what dose that mean do you grow it normally ie. same light through the whole grow and nutes

Howdy.I tried putting this in the cannabis law's section but it's password protected or something so decided i'd put it here. What I want to know is how many plants are considered a commercial amount and what do they class as PERCY?.I done a quick search on google but it seems hard to find a quick straight forward answer(could possibly do with the exsesive billbrees tonight).Any input would be much appreciated.

Found some seeds I had in the cupboard and was going to turf.Instead I thought I would give them a run.Had 15 non fem seeds 10 sprouted lost 2 so I have 8.Obviously I dont want the males.I had them in my grow room with my other plants but took them out and put them in a box for 3 days without light to try and sex them.It didnt work.Can anyone tell me how long after going to 12 will they sex and will they re veg when I put them outside. My time and room is running out so i might just end up putting them out now just didnt want to waste time and nutes on male plants and dont want them to pllinate the girls..
