Just wondering. If I buy a 600w HPS ballast, can I use 250w or 400w bulbs in it? I'm going to be using MH conversion bulbs also. cheers

best lights are HID lights - HPS (High pressure sodium) & MH (Metal halide) MH light are best for veg stage, HPS for flowering. You will need at least 1 600 watt balast that will power both bulbs. You can buy MH bulbs that will work on a HPS balast, make sure it has an E40 fitting. There are...

Hey there growers, It's almost harvest time in the big smoke, but a family visit tomorrow night means I have to switch off the lights & fans for the whole weekend for stealth reasons. I like my trichs to be around 20% amber and the rest cloudy but at the moment they are more like 50/50...

unless you have limited space - don't cut anything off, leave them alone or face stress related problems. and even if you do have limited space, use LST where possible. And I tuck my fan leaves under my buds for more light, never had one snap yet.

if it is nute burn, i think it should eventually subside, give them a good flushing with clean, ph adjusted water and then leave them for a few days before watering again. Good luck

me and a friend grew outdoors in his back garden, the weather was shit all year but we did get a small yield. They grew pretty big - started in April, harvested last week (beggining November) 2 x northern lights crossed with skunk and 2 x northern lights clones from my indoor grow. The buds on...

purple leaves can be a sign of extreme low temps (usually for an outdoor grow) Here's my outdoor Northern Lights that did the same thing -

A friend of mine put coffee grains in the soil - she swore it worked!

Really don't know how you can possibly achieve this with that space. Most strains take at least 8 weeks to flower + vegging time, unless you go with a lowryder strain that takes around 9 weeks from start to finish. The best lights to use are HID (high intensity discharge) like street lighting...

PH down (80% phosphoric acid) is very strong, so add only a few drops at a time and increase slowly to achieve the correct PH. It's also good at cleaning limescale off stuff :)

It is NEVER better to use CFL bulbs over HPS or MH, they just don't pump out the lumens like a HID bulb does.

600w & 5/7 plants in a 3ft x 3ft space? You have to do Bonsai MJ and you would cook them!

I've had a pretty good harvest (around 3 oz if i remember) from 1 northern lights plant using only a 100w HPS. You can grow a couple of plants with a 200w HPS but don't expect amazing bud. Watch your temps in that space, intake and extract fans are essential, I use a few PC fans. I would buy a...

would it be better to freeze the trim before mixing?

Well, had a good look and took some good pics. The NL x Skunk (the 2 on the right - less purple) are pretty much ready, gonna chop next Saturday. My 2 cloned NL (the beutiful purple ones) need a couple more weeks I think.

thanks twistyman, will know more when i get to see the trichs. Pics will be on the way :)

Hi All My friend has 4 plants flowering outside, 2 NL x skunk & 2 of my NL clones. I haven't seen them for a while but my friend wants to harvest them as the temps are dropping here in UK, they've only been flowering 7-8 weeks. The night time lows are getting to 5C (40F). Is it worth leaving...

I had the same problem a month ago, hung my buds up, went away for a week's holiday. When I got back they were really crispy. I re-moisturised my buds by putting my open curing jars in my shower room, closed the door and took a shower. This re-hydrated my buds and allowed me to cure them as...

I recently bought some organic black strap molasses and used it on my cloned NL at the start of flowering. I really think it made a huge difference. Don't flame me for this - table spoons and tea spoons, different sizes yes? As I only have 1 plant, I use 2 TEA spoons / 2 litres of water and...

I really don't think theres much point in curing that small amount of green, it's probably dry already. What did you harvest, a marijuana bonsi? You really need help with growing if that's your harvest.
