The plants on the right are Magic Bud, from clones taken in May. I planted these in the ground about 10 days ago, as they were beginning to yellow and were root bound. The ones in the middle in red pots are Arjans Haze #3, grown from seed in June.

Next is a closer shot of one of the Magic Buds. I think you can just about see the buds!

nice man, im looking forward to see how the Arjans Haze #3 do :]

Hi GM - This is my 3rd time with AH#3, but this is the first time I've let them start flowering ourside. They'll have to come in before they finish, they take about 12 weeks, and by that time it'll be too cold outside.

Just realised - it's a year ago today since I joined. Happy anniversary to me

Yeah you going to bud outdoor for as long as possible?

That's the plan. Just praying for a mild autumn.

Happy anniversary mygarden..

Thanks Andy, don't time fly..?

I did a AH#3 cut in my polytunnel last year. Never really got flowering properly before botrytis ate it about 2nd week of october The Rhinos i did had to be brought in at that time to finish cos of the same.

Hi Olive - yeah, that's something I am worried about. My p/t was covered in condensation this morning, despite haveing all the vents open overnight. Tonight I've left the door open too. I'm gonna get round to insulating with bubble wrap, and I think I'm also going to have to get an extration fan in there (plus an oscillating one). I'm still trying to work out how to fix the out flow without cutting a hole in the p/t.

Have you power to your tunnel?
if so, is your tunnel small enough, consider burying a fan outside (waterproofed of course ) and extracting that way? bury your ducting, soil pipe is excellent, with extract top of end of tunnel farthest from vent.

Good idea Olive. When you say "Extract from top end of tunnel furthest from vent", do you mean up high at the roof (as you would for an indoor grow) or just at the opposite end from the vent?

I've been leaving the door open, but there's still some condensation in the mornings.

Ha, sorry realised it didn't make sense. Hmm, less bubble me thinks.
Yes, just like indoors, highest point in tunnel for the duct/tube/pipe, and as far as possible from the open vent( otherwise will just suck fresh air out)
Ventilation is the key, but it's a bugger to deal with as condensation and poly always happen.
Best of luck

Hiya Mygarden,

I would try just using bubble wrap on one wall of the p/t first and see how much condensation gets trapped between p/t and b/w and see how long it takes for it to evaporate, if it holds a lot of condensation it might be better leaving it out, as long as you have an oscillating fan powerful enough to go through the whole p/t, leaving doors/vents open 24/7 will be the best way to go about it I recon. Let’s just hope the temps don't drop too much because then we will have to close our p/t's and still deal with the condensation. Good luck on whatever you decide.

Peace,
GG

OK, I think I'll try GG's suggestion and bubble wrap one panel first and take it from there. I'm going to try to do it so that there's a gap between it and the P/t. It's just a matter of trial and error, still I suppose that's how we all learn what works (and what doesn't). But I think there'will come a time when I'll have to install some extraction -and some form of heat.
GG - at what sort of temps would I need to close the vents and door?

Interested to see how you're getting on with your probs mate?
a little update?

Hi mygarden, I reckon you'll really benefit from a dehumidifier. Not only does it remove moisture it also warms the air by a few degrees. It's a big investment but you'll not worry about the damp year on year. How's it coming along?

Hi Olive - The Magic Buds are coming along nicely. No yellowing and they seem to be coping OK with the temps. I did an indoor grow of this earlier in the year, and I think the buds were bigger indoors at this stage, but we'll see how these finish. The AH#3 are suffering though. Had to spray them with ...Oh shit can't remember what it's called, that stuff comes in little packets and is a fungicide used on veg etc...anyway, gave everything a good spray with it the other day, and seems to have stopped the mould. I figured that if it's Ok for veg it would be OK for herb. A bit worrying that it's left a residue on the leaves and buds, but I don't think it's systemic so I'll give everything a good spray with the hose to wash it off before I harvest.
I went ahead and insulated the top and sides of the P/T with bubble wrap, just tucked it under the support bars to hold it in place, but I left both the end walls. A bit of a compromise as it does cut down the amount of light getting to the plants. Still leaving the vents and door open 24/7 to control the condensation, but that's a compromise too. This outdoor growing lark aint easy!

Irie - I do have a dehumidifier, but it struggles to keep the house dry when I do an indoor grow, so not sure it would cope with outside. But with the temps dropping at night now, I think I will have to try it. As I mentioned in your thread, I have some Haze's in the open, and I'm worried that that strain won't take the cold. But I really am putting off bringing them inside to save my leccy bill!

I just remembered what the fungicide is called, Dithane 945. I had a look on Bayers website, and this stuff works by coating leaves etc, forming a barrier against mould. It's not systemic, so I can wash it off before I harvest.
I think I'm gonna have to start untucking the bubblewrap from the sides of the tunnel, leave it hanging from the central support and rolling it up out of the way during the day, to let more light in. A right rigmorole, but it really is quite dull in there, unless the sun is strong, and I don't think my girls are getting enough light for a good crop. The rip stop cover doesn't help to start with.

Another quick update. Took all the bubble wrap down 2 days ago. It was way too gloomy in the P/T and the buds weren't developing. I also put my dehumidifier in there and have run it when the temp has gone below 10c (with the vents and door shut) but it's not collecting any water. Not sure why, cos there's condensation on the walls when I go out to switch it off in the morning. No sign of browning pistills yet, so I think at least another 2 weeks to go. I thought these would be done by end of October, as they took 8 weeks indoors.

No sign of rot or mould on the magic bud - touch wood - but a couple of the AH#3 had some stem rot, so I sprayed them with diluted hydrogen peroxide yesterday. And the ones I had to evict from the P/T and leave outside are now in my bubble wrapped G/H. Some of the lower leaves are yellowing, but they always do, no matter how they are fed or size of pot etc. They are way behind the MB and the other AH I left in the P/T.
