2 x 600 watt led perpetual grow newby advice

Hi guys. I have a good quality 1.2 x 2.4 tent and 2 x 600 watt led lumatez zeus lights. I plan on growing autos and am new so bear with me haha..

I have a 1.2 x 1.2 separate tent and 1 x Led of the same light for this tent, and would be very grateful for advice on what would be a realistic yield of autos while growing 8 plants in the main tent? And is it realistic to expect a yield every 5 weeks if i use the smaller tent (as week 1 to 5) and flipping them into the main tent? I'm thinking many autos are ready to harvest in 10 weeks or am I wrong here and what autos are regarded as higher yield as those are what I would go after

So I'm looking to harvest every 5 weeks or so by having a perpetual grow. Using the smaller tent to feed the big one. And when dalialled in what yield may I expect each harvest from 8 plants in the main tent. More than happy to alter the number of plants to max yield and will take you guys advice.


Sorry if this isn't clear and I look forward to any replies

The flaw in your plan is you are expecting the plants to finish on a set time scale and plants really don't work like that. It would be impossible to even guess at a yield.

Autos are not a great idea on your first grow. Autos can be as simple as can be or a complete pain in the arse. If you have a photo period plant in veg and you fuck something up, it doesn't matter as you can let a photo period plant veg forever, it will always have time to recover. However, as soon as an Auto is germinated the clock is ticking. An Auto normally has 30/40 days of veg and it is flowering, any recovery time needed due to stress from training or anything that goes wrong is time lost that you can't get back. This will affect yield.

IMHO, a perpetual grow is a more advanced growing method. For you first grow you should aim simply to keep them healthy and get them to harvest. Then when you have your setup dialled in and you are more confident in what you are doing you can start with the more advanced stuff.

Again, IMHO, a perpetual grow would be best done with clones. Seeds are always a complete gamble, you have no idea what you are going to get. If you have clones, from a known mother, then the results are always going to be similar.

Welcome to RIU

Well most of my experience is with exactly this , 2.4m x 1.2m flower tent and a 1.2 x 1.2m veg tent.

But I've never grown an auto and there's no need.

Most strains I run for 10 weeks, if they need longer they'll get it. But most strains, listed as 8 week, run 10 week from flip.

Crop every 5 week, sure things don't run to a strict calendar, but on average that's what I get.

One difference is I prefer to veg with a 400w mh or 315cmh .

I've run a perpetual for years, even when I've moved , just done it for other people with the same set up.

I can't tell you what yield you'll get with autos because I have no experience with them and they do what they want so your handling control away to the plant.

I can tell you that with your lights and strains I know in that flower space I could pull 24-32oz every 5 weeks , not including drying time.

I'd consider going photo periods personally, you've got control and you also are only running those two LEDs for 12 hours instead of 16-24 hours.

That's what works for me, I'm sure you'll find what works for you

I'd like to add the dangers of a perpetual in one flower tent.

A herm can cost you two crops if things get pollinated bad enough. Then your back to square one.

Bugs are harder to treat because you always have flowering plants on the go.

Sorry, I should say , my methods are different to what you plan, though the equipment and footprint are the same. I've just cottoned on to one of your questions.

If you put all 8 plants in a 1.2m x 1.2m for the first 5 week then shift them to the bigger tent your going to have to seriously manipulate them to try and fill that space which is twice as big.

To me you wouldn't be maximising your equipment or space.

But if you do it , please tag me so I can follow along .
Interested to see how it works for you

Thanks very much for your input. Do you mean your getting a 10 week from clone to harvest roughly then?

I will take the advice and defo avoid autos guys thanks and will obviously keep grande plans back until I can actually grow haha

Does 8 plants seem the ideal then? 4 under each light

No mate, from the point they go into the flower tent it's 10 week flower time, so it's staggered , half n half, so a crop gets chopped every 5 week.

They spend 5 weeks vegging in 5gal pots but they sit in smaller pots for a while, building root mass without taking much space, then when they get potted up they explode.

But yes, 4 plants per flowering light is my ideal, doesn't always happen, sometimes things get away from you and you end up using only two and filling the space that way.

So essentially big tent is always flowering
Small tent is always vegging.

Usually, a perpetual is supported by a small propagation area where you hold a couple photoperiod moms and start clones.

Once you have established moms you can run something like this.

Start/Week 0 - Take clones
Week 2 - Move 4 clones into veg
Week 5 - Take clones
Week 7 - Move 4 vegged plants to flower, Move 4 clones to veg
Week 10 - Take clones
Week 12 - Move 4 vegged plants to flower, Move 4 clones to veg
Week 15 - Take clones
Week 17 - Harvest half tent, move 4 vegged plants to flower, move 4 clones to veg
Week 20 - Take clones
Week 22- Harvest half tent, move 4 vegged plants to flower, move 4 clones to veg
Week 25 is back to week 15 and the viscous cycle continues

If I wanted to just do the full grow from start to finish In both tents, so both tents doing their veg/flower stage in each am I really looking at around 25 weeks for a harvest?

I do have a propagator that's heated and has a great deal of space

More like 15 weeks, you can clone more plants and fill the veg space faster that way.
2 weeks to clone. 3 weeks to veg, 10 weeks to flower.
Once your grow is established your grow area will produce what it's gonna produce. You will get 1.2 square meters of product every 5 weeks.
Just up to you if you want to process ever 5 weeks or 15 weeks.
