Default Grover Sativa's guide to UK GreenHouse Growing

I have grown many many g/h crops in the UK with different levels of success.
Here are my tips , you may not all agree...

1) Go for an early variety - you can grow normal indicas, even skunks in an unheated greenhouse but they will flower during colder and cloudier conditions of a September/October flowering period when the sun is also less strong. Your aim is for an August/September flowering period. The sun is stronger and you can have HUGE buds (I will soon post a pic to prove it!)

2)Don't believe any companies when they say "also good for outdoor/greenhouse" - they are not talking about the UK... If it is not specifically for early grows then forget it. Good examples are any skunks which are not early. My Skunk 1 has been flowering for just 1 week. This means that it won't finish till near Nov, risking mould, weak sun and creating a need for a heater (hey, I just LOVE the challenge). My early Californian indica, on the other hand, will be in her 7th week by now and is more or less done and looking SEXY SEXY SEXY.

3)If you can, plant direct into the ground. There are so many reasons for this.
Temperature stability at root level. It is virtually impossible to over-water. You will need minimal flushing. It is much harder to over fertilize. The roots can grow bigger and get more food and water for your buds. The plants will be more vigorous and healthier. Plant in a small pit to catch the water.

4)If you plant into the ground, prepare it EARLY. Even this year. Dig in shit loads of organic matter, make sure it is well rotted. Add a small handful of bonemeal and grow-more, a small bucket of perlite if you like, any good quality second hand compost from your indoor grow is also good or other soil improves are cool. Try horse manure. rot it very very well. Don't use too much. Kitchen Waste Compost is best. Recycle your food waste.

5)If you MUST use pots these tips are VITAL..... Use the biggest ones you can. The bigger your pot, the bigger your buds. I saw a photo on this forum the other day of loads of plants in 10 litre pots. These are WAY TOO SMALL... 40 litres minimum. Smithy pots are good, Muck buckets are good - try Homebase or B&Q or your local garden centre for these. Dig your pots into large holes in the ground. This will protect the roots from temperature changes at night and give your plants more room to grow. DON'T USE BELL SHAPED POTS. EVER. I can't stress this enough.

6) DON'T USE JOHN INNES. It is shit. It is full or grit which is very heavy and strangles roots. It also contains Lime. This is not good at all. This Lime is to bump up the pH (which you don't want) and washes out over time, which leads to unstable pHs and pH crashes (which you don't want). The pH is too high, at 7. Aim for 6.

7)Don't mulch with anything organic. You will create mold and insect problems.

8) DO mulch with hydro-lycca, if you can find it. It will stabilize root temperatures and stop your delicate top roots from being smashed by your watering. If you are skillful, the delicate roots will grow UP into the hydro-lycca like a kind of hydroponics. Soiloponics! I have seen no insect problems using this but concede that a lot of people don't like to use any mulch at all.

9) I think someone suggested Mango Haze as an option. FORGET IT. It won't work. Believe me. Not in an unheated greenhouse in the UK. I know. Trust me.

If you like Haze (and I REALLY REALLY DO) go for Early Skunk/Haze or Early Haze. There isn't anything else for you.

If you like Skunk go for Early Skunk

Other Mr Nice options are Early Queen or Devil. You could try shark shock but go for Early Skunk instead.

10) Don't plant too early. Plants grow HUGE in the greenhouse.You will be pruning. (Keep these clippings OUT OF THE GREENHOUSE or you will create problems.) Mid June is fine. Even later - right up to August or beyond for short season small crops...

11) Don't have other plants in there, such as tomatoes. They will only increase the likelihood of insect/botrytis problems and will take up valuable buddage space.

12) Don't be too patient - if you can harvest it, harvest it - a plant in the drying room is worth two out in the bush, know what I mean?

13) try some auto flowering ruderalis types for the early period before your main crop are planted. These will tide you over and do really well in the greenhouse in may/early June.

14) FINALLY - DON"T SHOW OR TELL ANYONE. Not until after harvest, anyway..


(I am going for Early Skunk/Haze next season..)
Good Luck - Grover Sativa

"im running ssh alongside toms and other stuff.i had no choise this year .... they all got dumped in the greenhouse......

iv been thinking of heating the greenhouse........"

=============

Herbm - respects for your good taste. The SSH...not only my fav grow but nearly my fav smoke too (Nev and Mango Hazes just edge it for me. Well done Shanti and Nev - from all the community.)

Absolutely shite in the UK greenhouse, though!

I really hope you prove me wrong..Just promise that if a semi-decent harvest starts to develop you'll ditch the tomatoes. They are notorious carriers of botrytis and cause havoc in the soil with bugs and insects (which is why it is hard to grow them in the same place 2 years in a row...) How many tomatoes would you swap for just 1 good ounce of the SSH?

Haha - how many times have I dumped spare indoor plants in the greenhouse only to be disappointed? The only time I was pleasantly surprised was with a white skunk which is now called Shark Shock (but was called something else back then...) Even then I reckon I could've done a lot better with a good early skunk and a couple of auto-flowerers either side...

Still, if you have green fingers (and I'm sure you do) you will always get SOMETHING..

On the other hand, a heated greenhouse really would increase your chances of a good harvest. I use a green electric greenhouse heater. They are sold all over the place for about 20squid. They have pros and cons.

The trouble with them is that they blow the heat out and this is damaging and desiccating for leaves and buds. You have to aim the air away from your plants which means that the heat isn't going exactly where you need it. Still, it will heat up the whole g/h generally. Try not to blow the hot air straight out of the window! A much better option is heated tubes, kind of like underfloor heating, which radiate heat but these are more for the professional (again, someone prove me wrong on this and tell me where a cheap option can be found, please)

You will need ventilation to avoid moulds. A good extractor is best - but unlikely and expensive for a 6 ft by 6ft g/h and definitely increases heating costs. The easiest way is to use the window! By hand is a pain, better to get one of those auto open/shutter things. They are cheap and work by gas pressure, I think. Again I recommend these because they are thermostatic - you can set the temps at which they open/close, just like the green electric heaters.

The trick here is to strike a balance between the temp at which your heater strikes up and the temp at which your window opens and shuts. If the window
opens too early your heater loses effectiveness, too late and humidity becomes a problem. Likewise with the heater. You need to get a 'feel' for the climatic micro-system (wow - great phrase).

It is worth repeating something that I know you (herbm) and I don't need to hear again but will be of possible life saving importance to less experienced growers...
ELECTRICITY AND WATER DON'T MIX. If you can't do it safely, don't do it at all. Really.
The plug for my heater runs OUT of the greenhouse into a kind of plastic mini house which is where the garden electric cable runs to. This is totally rain and dog proof and STURDY. There are no electric points in my greenhouse. There is a surge protector at the other end of the garden electric cable, where it plugs in inside my house...At no times are any electric points or items just left on the ground. In the greenhouse, electric items, such as heaters, should be raised ABOVE the level from which you water (somewhere between knees and hips for me.)

My overall view on heaters is this.. The whole point and joy of outdoor/greenhouse growing is that you are using the sun and ground and air instead of HPS's, pots and fans. These things are natural and best of all, FREE. Heaters are very expensive. Try to choose varieties that come in before the need for heaters or which will come in with only minimum heater use (around the end of October/beginning of November) most skunks are good for this - but some can be mould susceptible so choose carefully, the F1 skunk hybrids are usually slightly hardier.

That said, if you don't mind spending the money and you are a confident and attentive grower with a little bit more experience, greenhouse heaters will greatly increase the range of varieties you can choose from, just like the greenhouse did in the first place.

Swap the toms for a heater then you can smoke ten SSH joints for me! (outdoor is always more psychoactive than indoor, too, you lucky grower)

What does my Skunk no1 look like today?

I stress that the big bush in there is just 1 plant!

There is absolutely no mould on her at all. I only put the heater on 2 days ago, she is tough - no doubt. She is pure skunk (actually, The Pure from TFD...) and the stink when you open the greenhouse door is just tremendous. Really sweet and FUNKY.

She is in a huge pot (60l, maybe) which I dug into a hole in the ground to protect the roots and because she got so fucking BIG.

The funny thing is that this grow wasn't planned either. I had the space and just stuck in a skunk cutting because I had it spare and most everything else I had at the time was Canadian haze or Kali Mist.

She is in whatever recycled soil I found in various pots in the garden. I fed her with spare tomato feed, Chempak leftovers and a bottle of "Organic Fruit Food" that I got reduced for 3squids down at B&Q!!! (Actually, it is GREAT STUFF. Bargain.)

I DID check water pH levels and EC levels for the feed, though (old habits die hard...)

How good would she be if I had put in more effort with the soil and paid more for the feeds? Next year, maybe...

as for this year...well she has started to mature a few days ago now and with this girl, when she starts to go, she goes quick.

I'll flush her with pure RO water until she is done and harvest as soon as I can.

I have to stress than none of this KIND will find its way onto any markets anywhere. It is all MEDICINE.

Check out how the tiny top roots grow up out of the soil and into the hydro-lecca, like hydroponics.....Soil-o-ponics.
