Pot switch

Hello there guys, posted in here abit but a little run down on my growing system... 

 

I use a wilma xxl 8 pot system, 3 x 600w hps. 

Just completed my 4th grow so still a novice always looking to improve. 

 

1st grow I used;

18 litre square plastic wilma pots, 100% coco with 2 inch of clay balls

 

Second grow I used 25 litre square plastic Wilma pots with 70/30 coco perlite 2 inch clay balls at the bottom. 

These plants tried to grow 2ft bigger than my room height so alot of tying down and super cropping was involved, extremely close to the hps and it was heatwave season so most of the grow was done at the 250w/400w setting.

Resulted in 25oz, some burnt bud, very airy bud too. 

 

3rd grow I ran Dinafems ocean grown cookies, 

18 litre square Wilma pots, 100% 2%charge coco 2 inch clay balls at bottom. 

Also put a big tube heater down the middle of the Wilma to help root temps at lights out. 

This was by far my favourite grow which left me about 35oz of tight purple frosty nugs large.IMG_20200107_210926-01_compress85.jpglarge.IMG-20191215-WA0003.jpg

 

4th grow I wanted to try and keep improving, I opted for 12 litre airpots with 70/30, I set up a drip ring using 4mm hose and t peices. I did however forget to put the tube heater down the middle of the Wilma, I do beleive light out temps was too cold and the pots definitely Contributed to the roots feeling it, all my plants hermied. 

 

I broke up the 70/30 into my compo bin last night and the roots inside the airpots was pretty impressive tbh, when I used my square Wilma plastic pots majority of the root mass is at the walls and the floor of pot where as the airpots it's throughout the whole pot and alot of them! 

 

So what I've gathered knowledge wise I want my 5th grow to be the best yet! 

 

I've had my best yeild results from the 18l square plastic pots with tube heater using 100% but I would like to give fabric pots a try. 

I will use the drip ring as the feed is evenly distributed into the coco. 

 

Any little tips or methods you guys use or acquired through your experiences? 

 

If I did try fabric pots, what size would you recommend if 18l plastics are my preferred size. 

 

Do you use clay balls at bottom in fabric pots? 

 

Also how do you Wilma users keep those pots toasty? I have a intake box with oil rad and that 1x 1.5m tube heater.. Could do with a couple degrees higher for those cold mornings tho, another tube heater maybe?

Thanks @monkeypig, I'm adding an additional 4 gang incase I need to add another tube heater on a timer and I may try a Maxijet res pump instead of airstones as something to do with them changing pH or oxygen levels.

Hi mate,

 

I know it's been suggested before, but I'd really recommend giving 9l airpots a try with coco. 12l at the most. 

Using smaller pots is a no-brainer for me - still able to grow huge plants with great yield, less coco to buy and deal with etc

You just have to be able to multi-feed - mine would totally dry out in less than 12 hours otherwise. 

 

This plant yielded 227.8g, grown in a 9l airpot:

When I used fabrics, I liked a layer of clay balls at the bottom for drainage, and tended to go for 12l as finals. Don't think I'll be turning back from the airpots now though. 

 

With regards to your chilly mornings - is the boxed oil rad controlled by a thermostat within the grow room, or by it's own? 

I have an oil rad heating the intake, but also 2 x tube heaters at pot level on an independent thermostat to take the chill off if the rootzone drops anywhere below 22°C.

That's a killer plant syzygy! I will give the 12l airpots another go with some cuttings at some point but id like to try fabrics next. I was thinking 12l - 15l for finals with a inch or 2 of clay balls so bottom of the pot don't get soggy. 

 

My rad box is on its own thermostat as I don't want that box to get too hot, just enough to take the chill off the intake air really. My aim is to boost the root zone temps a little :george:

I'd go for 12l fabrics. You're not hand-watering so it just makes sense to go smaller imo. 

 

A long tube heater on it's own thermostat should do the job for your chilly root zones.

Yes multiple feeds isn't an issue at all, is 22 degrees an ideal lights off temp? My last temps his as low as 13 degrees some days :pitchfork: I will definetly rectify that

lights off temps really need to be 20 or above.

The closer lights off  to lights on temps - tends to keep the stretch down a bit, ive noticed..
