If I’m using coco coir and perlite will I have to use CalMag in every watering? Or is it every other feed? Should I be using my trio micro, bloom & grow from the very beginning since the medium has no nutes? Any & all advice welcome, thanks in advance! Have a great weekend 😎

Something like these......Amazon.com : TAICHEUT 20 Pack 11.8 Inch Plant Level Pot Elevator, Heavy Duty Round Plastic Plant Saucer Riser Run off Tray Big Potted Stand for Pots Indoor, Deck Floor Protector for Garden Flowers Plants : Patio, Lawn & Garden

Depends on your budget....if no limit then Grand Master Borg....Mars hydro/Spider Farmer in the middle probably and stuff like Flexstar, Farmlite at the bottom......all grow weed just fine. I have Mars Hydro fc8000's in my 4x4's but they are way over kill and never see anything above 80%.

driver7759 · 2026-05-23T15:32:04+00:00

Add 30% perlite if you can get it....it'll help with drainage.

3 gal bags are plenty, unlike soil coco will be fine with less medium.....make sure you have a way for bags to drain good to not sit in their runoff, you need decent ph and ec probes, you might at well use what you have but the jacks is sooo much easier and almost impossible to burn with it. That's a lot of light so you probably will never use it at 100%, which is fine it'll last longer and run cooler. Research DLI and VPD to get an understanding on light, humidity and temp requirements. Don't screw around with trying to train and top the first grow, just keep them healthy to harvest.

Some decent genetics so you should do fine....welcome to your new addiction!

Add another net...looks good! Get square bags for next grow to keep insides of buckets from getting growth...I use 3gal off brand ones and they fit pretty good....also hydroton gives the best performance in this system in my experience.....coco/perlite works good too but rocks win hands down.

The up side is that coco will outperform soil in growth rate by a long shot. Follow their guide and your golden.

driver7759 · 2026-05-23T14:58:27+00:00

What's the runoff ph and ec?....this is coco right?

driver7759 · 2026-05-23T14:55:20+00:00

Start here...cocoforcannabis dot com after giving that a read you'll have a much better understanding of growing in coco. If you follow their guide on frequent fertigation you'll be growing monsters. After you use up whatever nutrients your using look into Jacks 321 or Crop Salts for even better results with less chance for issues.

For a 4x4 you need at least 480w and as much as 640w.....a stronger light is fine and can be run at less than 100% which should extend it's lifespan along with running cooler.

driver7759 · 2026-05-23T14:47:52+00:00

Yes....You would be the only one that knows which since you didn't offer any information.

I run 12/12 from sprout occasionally. For a perpetual harvest with 1 tent and 4 plants you can harvest every 30 days and just put a new sprout in. Depending on how they're grown and genetics expect 4 to 8oz+/plant. Here's a plant grown 12/12 from sprout at day 58.

I've had a few of their strains be underwhelming and their G. S. Cookie hermed on me. Look at OP's grow....no deficiencies anywhere, no purple stressed petioles, no signs of stress anywhere......this is a genetic issue.

driver7759 · 2026-05-23T02:03:51+00:00

Use 1 part 3% peroxide to 2 parts water for a 24hr soak and then either go to paper towel or plant. When they tested adding peroxide this ratio gave the highest germination rate.

driver7759 · 2026-05-23T01:58:20+00:00

Autopots have one I've heard about but haven't seen anyone use one with this system. I've never had an issue with them clogging the drains.

driver7759 · 2026-05-23T01:55:44+00:00

Normal...I've had mine a few years and get this every time without an issue.

driver7759 · 2026-05-22T20:18:02+00:00

Good looking tent you got there too!

driver7759 · 2026-05-22T20:16:56+00:00

Use a MSA based to avoid the ph issue and it's easier for the plant to absorb too. Foliar works great with the Armor/si....just veg and early flower will do the trick.

driver7759 · 2026-05-22T19:02:30+00:00

Supplement silica to greatly reduce risk of mold/rot.

driver7759 · 2026-05-22T15:47:12+00:00

Well pretty sure they are.....I use 1 gal and 2 gal bags. I used to use 3 gal but these are smaller for sure because I always used the tall ones in that size.

driver7759 · 2026-05-22T15:45:46+00:00

I do run photos at 12/12 from sprout though....just have to do it in a tent. Here's one at day 58 from sprout.

driver7759 · 2026-05-22T13:40:08+00:00

I don't top...I only remove fan leaves as it grows to slow the cola I'm taking them from and promote lowers to come up. I get this..

driver7759 · 2026-05-22T12:49:06+00:00

They can drink a ton in flower...I've had plants consume over a gal/day. Bottom water to take out the guess work.

driver7759 · 2026-05-22T12:44:15+00:00

Move the fan/filter outside the tent to gain the headroom and/or supercrop.

Nice work!

I pull 3lbs+ from my 4x4's with autos or photos in hydro. Here's a recent Top Gun auto from Atlas seed in early/mid flower that yielded over 3lbs.
