2 weeks I recon. Or maybe the end of next week. Just want as much growth as possible before I switch. I know when they go to 12/12 there will be a huge growth spurt, so maybe switch sooner rather than later

Is the Hempy really that simple then? Could I fuck off for a few days and they'd still be fine? How often are you watering yours Matty and Grape?

I'm watering once every 3 or 4 days mate. I actually add more soil rather than perlite/ vermiculite so it holds more water and I don't have to water as much. But this is not what I should be doing. I should have done it the other way around. Next time I will do this so the root system get more air

Excuse my stupidity but what is DWC?

Not stupidity at all mate. I didn't have a clue what Hempy was!
DWC stands for Deep Water Culture. It's an hydroponic system. Ive got one bucket, its probably a 20 litre bucket. But it always takes 15 litres to fill. Instead of the perlite/vermiculite mix you have water. Water is the growing medium.
The water is oxygenated by an air pump like you would find in a fish tank. I'll get some photos up mate to better describe what I'm trying to say lol

image.png Right, this was taken from day 21 from seed. That net pot is full of pebbles. The roots are suspended in the nutrient solution which is constantly being pumped with oxygen. Most common way is by using a an air stone that you'd commonly find in fish tanks.
I'll take some photos on Saturday pal of the root zone. It is unbelievable how fast the roots grow in this system.

Just looking back through the notes, one little root had just poked through the bottom of the net pot about 5mm 7 days before this photo. Just goes to show how quickly the roots grow. i wish I'd kept a photo log now of them. I'll take a pic tomorrow to show you what they look like now.

Just water with your nute solution and that's it. I water mine every other day or every third day but you can probably get away with not watering for 4-5 days depending on the size of the container. I find some plants are thirstier than others. At "night" is when they drink most of the water but I'm sure you know that. Water everyday if it's full on heat outdoors <-- bit of a burden really. I ph with a colour-coded meter so I guess you don't need to be THAT accurate about the ph either. The vermiculite has some ph-altering properties so it's not 100% inert medium. But you can run all perlite or, sometimes, I like to add in rockwool croutons with the perlite. However, note that rockwool is not biodegradable if you care about that sort of thing. There's this one dude who runs 100% rockwool hempy buckets... it's amazing :D

@mattyblade1 it's common practice with hempy buckets to soil cap the medium. It'll spread out the water when you feed and prevent light from going in. Sometimes on vigorous plants the roots will grow up and dry off so it's worth keeping in mind. it'll maximize the efficiency of your container. Me I run 4.5L containers with very small plants so I don't feel it's necessary for me but I've had roots grow upwards once and I wished I had capped.

I like the sound of using all perlite, because I hear you can wash it and reuse it? Can't be arsed with throwing out dirt and buying more and all that lot, would like to keep it dead simple, I'd alwo like to use some pots around the similar size, 4.5l. I think they'd be ideal just for a few autos in the corners of the tent. Gonna have a look for the 100% rockwool aswell sounds great!

Thanks for the advice Grape it sounds good. Nice roots there stick. I've grown in 100% perlite before wth excellent results. The only downside for me was continued watering as the water runs straight through the pot. This now why I use 30% soil wth vermiculite mixed in. I will say that the results I got though we're as good as anything I've done before.
