Prima volta coltivazione idroponica

Ziocannabis The only problem at the moment is the pH, which jumps up by 1 point every day... from 5.9/6.0... to 7, even 7.3... New problem: I need to add another porous stone to oxygenate the main bucket, so that the residues don't settle at the bottom of the pot... Okay, all done... I added a small air pump to the central pot... more oxygen besides stirring up the bottom with the bubbles...😉 It's gone up a bit E... now it's at 0.8... while the pH has stabilized around 5.9-6.0.

Ziocannabis Today, Monday 22/01, I changed about 40 liters of new and fresh solution... I noticed that towards the end, the water/solution was more "clear" compared to the first twenty liters... I believe that the porous stone with the addition of an oxygenator was helpful in the "System" bucket to avoid any deposits at the bottom. The biggest problem is the oxygenated temperature itself... it's impossible to keep it at 19/20° without using a chiller... it costs a fortune... about €300! Right now it's at 21.3 but it will definitely rise... usually it's around 22°... The dimmable LED light is at 80%... It's true that there will be leaves shading the pot... but I don't know if at 100%, when I put it at the beginning of flowering and lowered it to 40 cm from the top, what will happen to the temperature, in general. For now, let's move forward and try to solve one thing at a time 😉 I almost forgot EC at 0.8 on the 13th day in the pot... is that low in your opinion? The plants look great, in terms of color and trunk... Today (13th day) I put the two air pumps outside the tent (one was added for the control bucket). I will have to start "topping" the 3 Cookies, they are already at the 4th node and the stem is quite thick compared to previous normal soil grows.

For now, let's keep going and try to solve one thing at a time 😉 Today topping or FiMing, let's see what happens 😂 They're growing but... I think they've caught Tobacco Mosaic... a disease that deforms the leaves, the tips curl up and down, some leaves indeed show a kind of mosaic with yellowish spots. It looks good... today, February 2nd, defoliation and starting Monday we'll switch to 12 hours..... I think I'll do it this way... or I'll struggle to manage the heights and the area... I've noticed that the leaves and the trunk are much thicker compared to the soil with the same period of 3 full weeks...

Ziocannabis Everything seems fine.. I’ll wait two days and then I’ll switch to 12 hours. Later I’ll bring some roots, giving them the chance to spread out and strengthen... I’ll try to untangle them if I can. I need to prepare a support to hold my little girl well.. I’ll use an old chair, and I’ll place the lid with the plant in the center of the chair.. obviously without the seat cushion🤣 Let’s try to remove as many knots as possible between the roots and I’ll trim some of the uglier tips... anyway, not more than a couple of centimeters.. They are a bit low in EC and nitrogen... they tend to lighten the new leaves.

Ziocannabis The biggest one is already 85 cm... a real Gorilla 🦍 Tomorrow I'm changing a 50-liter one, let's say I don't want to risk burning the submerged pump by completely changing the water... it would be a problem to empty the system completely... I should have another pump to suck up all the 65/70 liters that are there now. One of the Gorilla Cookies has exceeded a meter in height by a couple of centimeters... the problem with hydroponics is that you have to do Scrog, at that point you can keep the height of the others too. I changed the base for flowering, much more suitable... Sensi Bloom A&B Advance Nutrients of course... I'm adding Big Bad... Now I'm trying to leave the roots exposed from the solution to induce water stress and accelerate the first phase of flowering... 5 to 8 cm out of the solution.

Ziocannabis I have to bend the branches of the tallest gorilla again, trying not to break them... last time, then I'll let them continue flowering... The other three are very behind, even though I planted them on the same day... I won't need to bend anything! In the bigger one in front, the roots have almost completely broken the mesh pot... I fixed it with a piece of wood and a shoelace to keep it upright..😉

Ziocannabis It's going great, even though one of the 4, the Tropicana, has grown little and poorly... mistakes that I will definitely avoid next time... all seeds of the same type should be planted and all 4 should be put under light on the same day... the only problem with hydroponics is keeping all the plants at the same height... for this reason, they recommend SCROG. Anyway, the biggest of the 3 Gorillas is incredible... I've never seen such a big trunk and such thick branches... Another thing I will avoid is exceeding 3 weeks of vegetative growth... 20 days at most... in this 150 x 150 tent, it's hard to move around, it's gotten so wide.

Ziocannabis Looks okay, but rinsing will be a problem... the one on the right already has milky trichomes, some of the sugary ones are amber... the others still have white pistils, I don't even look at the trichomes... it seems like there's a 15/20 day difference!

Ziocannabis There's not much time left, no more than ten days... The trichomes are all milky and already on the little leaves, amber. So I did the last solution change, with water at pH 5.6 of about 40 liters... from an EC of 1.4 to an EC of 0.5... I will continue only with pH-controlled water until I bring the last week to zero... let's say 😅

Ziocannabis It looks like a "decent" harvest... Used to plants over 100 grams, like autoflowering ones... let's see the final weight of these fast flowering photoperiods. As for the size of the buds, it's not bad, but I was surprised to have to harvest half of them so early.
